@Lennon Darren Thanks so much for your reply. I got to the site thru google and Im trying it out now. Seems to take quite some time so I will get back to you later with my results.
I want to point out that a broken flyback sometimes shows in an atypical way. I had a case where there was no noise and it was still building up some charge in the tube, but it was still dead. Also, when replacing the flyback, you should also replace the horizontal output transistor (HOT) and the snubber capacitor connected to it, because it's often a broken HOT that leads to a dead flyback, and on the other hand it's often a broken snubber capacitor that destroys the HOT (or broken solder joint on either of them). Otherwise, you might end up destroying your new flyback transformer.
I remember getting a shock off a crt a long time ago... it really f*cking hurt! It was a rented tv from radio rentals (there's one for the kids) To tune it the whole back had to be removed to access the small tuning knobs and of course this had to be done while turned on. So there I am standing in front of the tv giving it a reach-around to twiddle it's knob so I can tune in my Commodore C16 (we were poor, this reply is best with "in the ghetto" as it's soundtrack) and my forearm brushed something very live indeed. I really don't recommend it... I've had a few 240v shocks over the years but that was really nasty. Although finding out how awfully shit my new C16 was turned out fairly painful as well
Did much the same back when I used to have to repair CRTs as part of my job - familiarity breeds contempt and I got bitten. Naturally, in front of a paying customer. I _may_ have sworn, just a little. So, so much worse than when I gave myself a 240V belt in front of a (different) customer - although thinking about it, I think I swore that time, too. And then everyone laughed at me, the unsympathetic b.... :D
WARNING: The CRT tube is under vacuum. It will implode and shower glass everywhere if it cracks even a little. Arguably this is the most dangerous part of working on a CRT.
still crt can last years and years . i have toshiba crt tv working still age 30 years. though it has a flyback replacement few months ago. still good as first day.
Thank you Neil. Now, I've never been one for TV or CRT repair, but I have watched videos on CRTs, and nobody has explained the function of the flyback transformer as clearly and precisely as you in this video. Thank you!
I must have replaced hundreds of those Philips flybacks and power switches. A lot of their small TVs used the same items. The replacent switches never lined up, always had to remove the metal from the old one. I always wondered why Philips made the flybacks with the screen and focus on the wrong side. It made no sense. Both need adjusting live to get rid of the retrace lines properly and focus properly. You did a great job. On the neck board, I never had a tool for that. Always a screwdriver, plyers and patience to get the darn thing open 🙂
Brendan White I took a lot of CRT television sets apart when I was volunteering at a charity. I was recycling them, and now I wish I hadn’t, because they would be worth something today
@@infinitecanadian Sad thing is here in the states a lot of old CRTs were sent over to India for recycling due to the dangers of the CRT. Lately when I come across a CRT I snag it and rob the Flyback, Degauss Coil, and Yoke from it. If the Tube doesn't have any burn in and if I have room I keep the Tube if it's smaller then 21 inch.
Those Philips LOPTs in these and the 1084 monitors dropped like flies and were a good earner for repairers back in the day. And yes those crappy power switches. Philips also made VGA monitors for Osbourne computers here in Australia and they used to cook all sorts of inductors and were a good earner too.
OMG! Neil! Almost exact same story as yours, happened to me few yrs ago. I went to buy an extra Amiga to have one for extra parts. Checked local ads, found one for cheap, no picture. I sat in the car, drove uptown, I enter that living room and a total shock!!! It was the Limited Edition (Stefanie special edition) + mint CM88333 + a box full of floppies all included in that price. The lady had no idea what she had. Something like 20 quid. I completely restored that Amiga, installed a NOS keyboard (German edition to make it fully legit). Later i soldered in 512 kB of RAM from a spare motherboard, so now it is 1MB chip RAM. Now just to install a battery somehow to get that clock up and running. I wonder do i need to build some custom jumper so that Amiga "knows" it has a battery since the expansion slot is vacant.
I learned something. I always assumed that the high voltage from the flyback transformer was used for shooting the electrons at the screen but your explanation makes sense. The flyback doesn't connect to the electron guns but rather the CRT and even the word flyback describes what you said.
As I mentioned in a previous comment, I found a company in Europe called HR Diemen that seems to have all of the designs for pretty much every flyback ever made and can reproduce them. They are not cheap but it's nice to know that in future when new old stock is no longer available there is another option.
I wish I'd found your channel sooner! I spent the last couple of years learning to repair CRT's. It's great fun... after living a life of being terrified of everything inside one. They are actually pretty simple to work on! And it's a lost art! Took me a long time to find even a couple really good CRT repair books...
Mind at least sharing the name of those resources to learn how to repair CRTs? I'm on the same boat as you, learning how to repair them and I always welcome any new info.
they regulary turn up at Adswood dump in the TV section in Stockport. I have one spare fawn one ex some kind of PC going free but probable need of repair - lets assume it is a SVGA one.
Brilliant to see this monitor again! I had one back in the 90s for my Amiga, it went on to become the monitor for my PlayStation! Work your Magic Neil!!
PSA for anyone else: Please remember it's not just the CRT itself that holds a potentially lethal charge. Depending on your monitor, you may have a nice selection of caps on the board holding hundreds of volts
the input capacitor in the SMPS is probably more dangerous than the capacitive effect of the tube. The high kV from the tube will give you a hell of a belt and you will know about it, but there usually isnt enough energy to kill you. The 400V on the SMPS capacitor on the other hand, can kill you
Does anyone know of anyone around Carmarthen who could do this for me? Excact same model also assuming same problem going by the symptoms. I really don't fancy poking a screwdriver somewhere potentially dangerous. I tried Carmarthen Electonics Ltd, they gave up working with CRTs about 8 years ago :(
So I guess I should stop being a chicken and finally install the new power switch in my Commodore 1084S-P monitor... that didn't look that bad of a job to tackle. :P
I replaced the flyback in my 1084 monitor last Sunday. It was a bit easier, since there was no need to disassemble everything - it was easy to reach the flyback. The only thing was, the pins on a replacement had slightly different pin spacing - a fraction of mm difference, yet I had to fight with them a bit and add a new hole for one of the GND pins. But the monitor works again :-)
I have one of these with this exact issue. I just cannot find anyone local who will works on CRT repairs and I just don’t have the confidence to do it myself :(
Had this same screen for my Amiga 500. Great video and skills! Space Ace too! So awesome. PS - Great Christmas jumper! I have the same one. Time to get it out after seeing this.
Spent many a day in front of mine with an Atari, and I remember seeing them on TV. Mine came from Cash Converters for 70 quid, stank of cigarettes but worked fine for years until it was dumped in a chaotic house move. I did have to resolder the input socket once. They ran well in 60Hz! Alas I just can't look at a 50Hz CRT anymore, the flicker is painful!
This reminded me of when I took my PVM to a local repair-man to dissasemble it for me (I was too scared to discharge myself, even though it has a discharge circuit)... anyhow, when I got it back the image was so distorted and green, and it was making this huge high pitched noise... Called the repair shop and they said it probably got some water condensation inside from sitting in my trunk during the rain the previous night. Guess what - it wasn't that! I noticed some flashing from the side mesh of it and it turns out one of the high voltage leads that attaches to the flywheel was detached and it was shorting (like making this plasma arch) to the metal of one of the nearby capacitors. All fear aside I had to reattach it hahah. Good thing that that worked, but still not completely confident to dissasemble and clean a CRT on my own, there are high voltage capacitors there that are scary too - and even being careful it is not a feat anyone should underestimate. Thanks for the great content! ^_^
Brilliant to finally see someone do a video on these Philips monitors, cause over the years i've had 3 of them that have developed this same exact problem. I gave up on them thinking it was a major power supply issue, so it's a great to finally find out the actual issue, solution and where to get the parts. Ironically i'm yet to have a faulty power switch on any, but I know it's a very common thing to fail.
A tutorial on adjusting the red/green/blue alignment would be super. (so that white dots in the corner look like "white dots"; not an unfocused mess of red/green/blue). Thanx for the vid!
Good video - only about 9 months too late for me! I had exactly this monitor with exactly this problem (after a grand total of about 60 minutes use after acquiring it!) Researching it I was under the impression that it was not fixable. Wish I'd kept it now!
Hello Neil, great and informative video as usual. I was wondering if you, or anyone down in the comments-section, could tell me the name of the song used during the cave dweller shout-out? Would be much appreciated, as it sounds like a solid banger. Cheers from Denmark :)
I had the mk1 version of this monitor with my first 8088 pc connected to the RGBI socket. It was an awesome bit of kit, it doubled as a tv when I was at uni by connecting a video recorder to the scart (euro) socket. And could quickly switch between the two. Great to see one again.
@@RisingRevengeance I always was able to hear it till about 6 years or so ago and now I am 52. I would be able to hear the large screen tv running in the house if it was quiet. I can hear around 13 Khz or so, same cant be said about my eyesight,.
Always best to keep these things alive, not only are they much better for older content but keeping them going cuts back on the e waste. I used to have same monitor back in my old Amiga days, it's still well worth having as I believe I am correct in saying it's will accept a 15hz signal thus it's Ideal for those 240p games. I still have lots of CRT tv's and vga monitors but when it come down to the VGA's as nice as some are, I have a Mitsubishi's Diamond Pro 2070SB more than capable of doing 2k, none of them can do older resolutions and it's all 480p and above unless play around with super resolutions and run it at 120khz. This Phillips is a great companion not just for a C64 or Amiga but also all those old consoles that are pre dreamcast.
I happen to open up a Brionvega Agol 11 today to see how the fourhole propriarty powerplug works... I seems that most likely the brown and blue wires can be plugged with a C8 polarized plug, but there is a black wire and I'm not sure what it's needed for. Guess I'll have to test it with a multimeter.
I did a lot of Philips TV flyback transformers back when they were current. You normally don't have to dismantle the CRT base socket. Usually if you very quickly push then pull on the lead it will pop out. The new one just pushes back in and is gripped by the tang inside.
I miss CRTs! I enjoyed repairing them back in the day, I recently threw out my rejuvenator and all my Fluke Hi-V probes. Would have made for a good video - d'oh!
This is the same monitor I had for my Amiga 1200. We ended up throwing our amiga out due to the power switch breaking on the Phillips monitor (Had to hold the switch in), and also the Amigas HDD had failed and I was around 10 at the time and wasnt even allowed to attempt a repair. If only I was allowed to keep it I could have fixed both problems easily.
Whilst doing my school work experience for a week at a computer repair workshop I was taught how to repair Amstrad PCW screens, used to use two long screwdrivers to discharge to screen.
I had good luck with my very limited skills replacing the power switch. As to anything else, too timid. I feel I would light up like one of those x-ray men cartoons with bolts shooting out everywhere. Go big or go home. I went home.
I've been repairing a faulty dirt cheap GB for solid 3 hours now, and my hand hurts from holding the solder iron. Time to sip my co- i mean tea, and enjoy this show. :P
I managed to get one of these about 1 month ago for £40, came with manual and cables fir the amiga and the atari st The picture is fantastic and decent stereo sound too
This model of CRT is one of those monitors that I used to have and now regret having let it go. Along with my original Atari ST, Sega Game Gear and Ilyama 17" SVGA monitor.
Awesome video! Never though I would learn the cause of the beep noise was the flyback.. And thank you very much for the explanation of the flyback.. Now the name makes total sense for me.. Great content here.. Thank you very much and congratulations for the awesome channel..
If any of your other CRT's need adjustment in convergence or geometry, I am sure many who watched this video would be very interested in seeing how to fine tune an older set that has gone out of spec. I wish there were more videos of the information you shared back when I was getting into CRT refurbishments. It is a very scary project to tackle, if you know nothing about the subject.
Very cool. I have one of those, but It's been years since I've done anything to it. I didn't remember how easy it's to take apart. Many old CRTs are much trickier to disassemble.
thanks for your video. I've an ATARI SC1435 which has the same PCB mother board. And I trying to find the power on/off switch. But can't find it. And the TFT it's the same problem. Have you got any information where I can buy thoses parts ? Thanks for your help.
LOL, I actually made a discharge tool very similar to that for opening up an old imac. I honestly think it had long been discharged but hey, better safe than sorry.
I need one of those switches for my Olivetti PC, but there are a lot of similar ones and I can’t find the exact model, any suggestion on how to find a matching one?
That’s the first thing I did 😄 It’s a Preh ME5C. Nobody on Earth seems to have it. What’s funny is that it’s supposed to have some low voltages pins, but mine only has the mains ones. Apart from that, it’s identical. I need one of the same size to fit the lever that gies to the front of the PC. The switch itself is inside the PSU. Now I wonder if a regular AT PSU has the same switch, but on cable. I must check my pile of salvaged parts...
Awesome video and explanation. I have e Philips Brilliance 107P, that powers up and the degauss kicks in, but there's no dispaly. Could that be the flyback as well?
The title of the video made it sound to me like you failed to fix the monitor, reading it again I realised it meant the Flyback had failed. I remember playing Space Ace and Dragon's Lair in the arcade back in the day.
RETROMANCAVE, what circuits in the monitor does the flyback supply? the flyback outputs many voltages but to which circuits? what circuits does the B+ voltage supply in the monitor?
Fantastic, I have the first version of this monitor. It is still working (I hope for a long time to come), I don't particularly want to work on one of those. Great video, thanks!
I need to clean out my TV.. 40" beast. Pretty intimidating tube and charge, I haven't had the nerve to attempt a discharge. I opened it up a few months back to at least dust it with some canned air. Unbeknownst to me, removing the back kinda pulled the tray with the board out slightly and the right speaker unplugged as well as another that says CC. When I reassembled, I noticed the sound was out on the right side. Due to work, I hadn't fixed it until just yesterday when I opened it up again. The pins were bent slightly, so I had to bend'em back and then put the speaker and CC wires back into their slots. Then I took some up close photos of the board and looked at them on the PC. It's just layered in cat fur and dirt... Ugh, I dread discharging... I have the tools for it, screw driver, wire, alligator clip for the grounding braid.. but wonder.. can I stand on a wooden chair and attach the screw driver's handle to a PVC pipe and discharge from a distance?
obviously you must have troubleshooted the set before.. to determine it was the flyback?.... about 80% of the time it is a power supply problem causing no high voltage ...
I picked one of these up recently for £50, but sadly it's missing the front flap. Bit of a longshot, but does anyone happen to have a spare front flap for the Philips CM8833 that you might sell or trade?
I have a bad 1084s d monitor, its powers up but the screen is dead, no static. I thought it might be the flyback but can't find one anywhere, HR 46045 alternatives MSH-1FCT31/DCF1580 KFS60559/AM175714 ... Can anyone help please
always wondered what the hisss was the monitor wouldn't come on, I went through so many monitors back in the day, PS I can print you off a screwdriver if you need one to tackle those other monitors to focus and brightness.
Just had a new Flyback put in. The tech said the old one looked totally fine and made connection, but thought he would put the new one in anyway and it worked. 12 hours of use and I’ve got the same problem again. What could it be? I gave him a HOT to change but he said it was reading fine
Apart from the 1084s and MKII, which old CRT's (monitors or tv's) used the exact same component for flyback/LOPT ? How can I find out ? Buying a new flyback just seems too expensive relative to the cost of getting another monitor or removing an old flyback from another device.
One of my 12 Commodore CRTs, an 1084S that was working fine up until yesterday. I was working with no problems a week ago last time I used my A1200. Then yesterday nothing when I turned it on to play my newest Infocom game on my A1200. Well not nothing. 1. The red power light was not coming on at all. 2. I'm pretty sure I was getting high voltage because the 4 different times I tried I could hear the high pitch spin up when I turned it on and also could hear the wind down when I pressed the power switch to turn it off. I have many spare CRTs so I just swapped it out and played the game that I was looking forward to playing. I have watched a ton of CRT repair videos from you and many other Commodore & retro computer TH-camrs. This is not ringing any bells with the power light not coming on but the high voltage spinning up. Have you ever come across this?
Ohhh wow amazing My Trinatron Sony CRT stopped working 2 years ago, I turn it on it makes that sound, but no pictures. Do you think I have the same problem ? Its a 1980s TV (soon I'll get the model name)
Hi I am curious wondering if you could by chance help me fix my Philips crt tv? The model number that I have is 24PT6341/37. The problems I am having with the tv is the RF connector on the back has broken off. Secondly there is no sound on the tv either. The sound went out right after the RF connector broke off so I am unsure where the issue is as I am assuming that had something to do with the sound no longer working. Is there any way to fix the RF connector and the sound on the tv? Please let me know as soon as possible!
damn why every city has some CRT technicians except mine..I love CRT picture quality, unfortunally my most precious one died today and im kinda sad cause can´t find who can fix it..im actually starting to consider to learn electronic just to fix it and put a workshop exclusively for CRT repairings sorry my english sucks I know
Hey man I have a question I would be happy if you answer because i am having a problem with this myself, I'm looking to replace the flyback for a CRT monitor and the only spare I got is from a broken CRT Tv do you think they would be compatible if I put the Tv flyback in the monitor's place?
Spent a full day replacing the flyback on my 1084S today. I initially thought it was a failure because I got either black screen or a white screen with pattern depending on my flyback screen adjustment. After seeing th-cam.com/users/gibs2b (TinyLauncher is the greatest) run into the same problem, I finally figured out that I had to do the screen adjustment with the power on because it has to be exactly tuned before it works at all. Fortunately on the 1084S the pots face the rear and are much easier to get at without risk of shorting. Whew! Oh, and now that the flyback is fixed, the power switch failed permanantly a few minutes later. XD
one of my 1084s is starting to squeal. do u think it needs a flyback replacement or to be recapped? and do u think i should stop using it until i get it looked at?
That little animation is great for helping to understand this. What if it blips a little white dot, then shuts down immediately? This is a ~2000 zenith 25" I'm talking about. I hear some later CRT models shut down when something is wrong, but I don't know if that would obfuscate whether or not it's a transformer or if that little blip means it's working or what...
Excellent video, do you ever do Cub repairs? I have a working Cub for my beeb that I have had repaired a couple of times.... my concern for the future is that it is literally a dying art. A video on Cub maintenance would be very useful. Cheers Peter
Thankfully I dont need videos telling me not to mess around with Flybacks because I already learnt that lesson as kid when I opened up a TV to see if I could fix it and tried cutting through the big thick wire going to the tube with a pair of metal scissors shortly after having turned the broken TV off and unplugging it. Needless to day, getting zapped by 25,000 volts doesnt tickle (especially if you do it outside bare foot like an idiot)

Hi! what was the flyback model? the same used in the video?
@@pateixeira22123 Looked the same at the first glance. I have no idea, if the model was the same.
I have one of these with this exact issue. I just cannot find anyone local who will works on CRT repairs and I just don’t have the confidence to do it myself :(
Darren Ramsay if you’re in South Gloucestershire I may be able to help...
Had this same screen for my Amiga 500. Great video and skills! Space Ace too! So awesome.
PS - Great Christmas jumper! I have the same one. Time to get it out after seeing this.
Spent many a day in front of mine with an Atari, and I remember seeing them on TV. Mine came from Cash Converters for 70 quid, stank of cigarettes but worked fine for years until it was dumped in a chaotic house move. I did have to resolder the input socket once. They ran well in 60Hz! Alas I just can't look at a 50Hz CRT anymore, the flicker is painful!
This reminded me of when I took my PVM to a local repair-man to dissasemble it for me (I was too scared to discharge myself, even though it has a discharge circuit)... anyhow, when I got it back the image was so distorted and green, and it was making this huge high pitched noise... Called the repair shop and they said it probably got some water condensation inside from sitting in my trunk during the rain the previous night. Guess what - it wasn't that! I noticed some flashing from the side mesh of it and it turns out one of the high voltage leads that attaches to the flywheel was detached and it was shorting (like making this plasma arch) to the metal of one of the nearby capacitors. All fear aside I had to reattach it hahah. Good thing that that worked, but still not completely confident to dissasemble and clean a CRT on my own, there are high voltage capacitors there that are scary too - and even being careful it is not a feat anyone should underestimate. Thanks for the great content! ^_^
Excellent work Neil... my college days came flooding back...
"slide your tool under to discharge..." is a hell of a quote to be taken out of context.
I know tell me about it
It would be very unfortunate for the guy that put the wrong tool in there 😬
I've changed a few flybacks in my day with arcade monitors and always hated desoldering them. I can see the desoldering tool is really helpful.
Brilliant to finally see someone do a video on these Philips monitors, cause over the years i've had 3 of them that have developed this same exact problem. I gave up on them thinking it was a major power supply issue, so it's a great to finally find out the actual issue, solution and where to get the parts. Ironically i'm yet to have a faulty power switch on any, but I know it's a very common thing to fail.
A tutorial on adjusting the red/green/blue alignment would be super. (so that white dots in the corner look like "white dots"; not an unfocused mess of red/green/blue). Thanx for the vid!
Good video - only about 9 months too late for me! I had exactly this monitor with exactly this problem (after a grand total of about 60 minutes use after acquiring it!) Researching it I was under the impression that it was not fixable. Wish I'd kept it now!
Hello Neil, great and informative video as usual. I was wondering if you, or anyone down in the comments-section, could tell me the name of the song used during the cave dweller shout-out? Would be much appreciated, as it sounds like a solid banger. Cheers from Denmark :)
Sure that's the music from the Amiga demo "EON" by TBL - The music is by Hoffman who appeared in The Cave in a recent live DJ set
I had the mk1 version of this monitor with my first 8088 pc connected to the RGBI socket. It was an awesome bit of kit, it doubled as a tv when I was at uni by connecting a video recorder to the scart (euro) socket. And could quickly switch between the two. Great to see one again.
I couldn't hear that at all, and I'm only my late 30s. I have really damaged my hearing.
Only 26 here and I can never hear the crt sounds, I don't recall ever hearing it when I was a kid either tbh.
All I could hear is a washing machine, a cat meowing and arguing kids. Hope I get noise negating headphones from santa.
I'm 40 and I still heard it plain as day
I heard it, but I've got bad hearing. Maybe your device has something wrong with its sound
@@RisingRevengeance I always was able to hear it till about 6 years or so ago and now I am 52. I would be able to hear the large screen tv running in the house if it was quiet. I can hear around 13 Khz or so, same cant be said about my eyesight,.
I have 2 of those and my problem is that with white colors the top image becomes inclined/distorted to the left. Do you know if it's fixable?
You might have a loose yoke, if its just white.
Nice Video. One question though on this repair. Does Space Ace need a digital video cart for the CDI LOL.
No but it supports one. I don't have one but it looks fantastic
@@RMCRetro I'm impressed how good it looks for not having one. I might have to get that for my CDI.
And watch out for those CRT necks - they’re really easy to break!
Always best to keep these things alive, not only are they much better for older content but keeping them going cuts back on the e waste. I used to have same monitor back in my old Amiga days, it's still well worth having as I believe I am correct in saying it's will accept a 15hz signal thus it's Ideal for those 240p games. I still have lots of CRT tv's and vga monitors but when it come down to the VGA's as nice as some are, I have a Mitsubishi's Diamond Pro 2070SB more than capable of doing 2k, none of them can do older resolutions and it's all 480p and above unless play around with super resolutions and run it at 120khz. This Phillips is a great companion not just for a C64 or Amiga but also all those old consoles that are pre dreamcast.
Without me my tool is useless. Without my tool I'm useless.
Keep it up, Neil!
I happen to open up a Brionvega Agol 11 today to see how the fourhole propriarty powerplug works... I seems that most likely the brown and blue wires can be plugged with a C8 polarized plug, but there is a black wire and I'm not sure what it's needed for. Guess I'll have to test it with a multimeter.
A while back I powered up a monitor but forgot to reattach the anode cap. It took 5 seconds before the transformer blew up :(
I did a lot of Philips TV flyback transformers back when they were current. You normally don't have to dismantle the CRT base socket. Usually if you very quickly push then pull on the lead it will pop out. The new one just pushes back in and is gripped by the tang inside.
Rmc you need to get yourself a casio cmd-40.
It'll really look good on you
Best to discharge the tube twice as it can recharge.
Thanks for the wonderful presentation, cheers.
I have three of these. One working with broken cover in front, one have problems with audio, and one with broken on/off switch (wont stay on). :)
Just up my street thanks rmc
I miss CRTs! I enjoyed repairing them back in the day, I recently threw out my rejuvenator and all my Fluke Hi-V probes. Would have made for a good video - d'oh!
This is the same monitor I had for my Amiga 1200.
We ended up throwing our amiga out due to the power switch breaking on the Phillips monitor (Had to hold the switch in), and also the Amigas HDD had failed and I was around 10 at the time and wasnt even allowed to attempt a repair.
If only I was allowed to keep it I could have fixed both problems easily.
Whilst doing my school work experience for a week at a computer repair workshop I was taught how to repair Amstrad PCW screens, used to use two long screwdrivers to discharge to screen.
Cross the swords.
I had good luck with my very limited skills replacing the power switch. As to anything else, too timid. I feel I would light up like one of those x-ray men cartoons with bolts shooting out everywhere. Go big or go home. I went home.
That jumper has really K. O me 😂✌️
Great vid. Haven't had to change a flyback on any of my arcade monitors yet, but hopefully if/when I have to it goes as smoothly as your repair :)
I've been repairing a faulty dirt cheap GB for solid 3 hours now, and my hand hurts from holding the solder iron. Time to sip my co- i mean tea, and enjoy this show. :P
Just had this problem on my CM8833-II if i'm never heard from again you know who to blame :)
On the todo purchase list, nice CRT for the Amiga :) Thanks for doing such great videos.
I had this beautiful big CRT monitor that I regret having recycled. I was still living at my mother’s and I should have insisted on keeping it.
I managed to get one of these about 1 month ago for £40, came with manual and cables fir the amiga and the atari st
The picture is fantastic and decent stereo sound too
This model of CRT is one of those monitors that I used to have and now regret having let it go. Along with my original Atari ST, Sega Game Gear and Ilyama 17" SVGA monitor.
Awesome video! Never though I would learn the cause of the beep noise was the flyback.. And thank you very much for the explanation of the flyback.. Now the name makes total sense for me.. Great content here.. Thank you very much and congratulations for the awesome channel..
If any of your other CRT's need adjustment in convergence or geometry, I am sure many who watched this video would be very interested in seeing how to fine tune an older set that has gone out of spec. I wish there were more videos of the information you shared back when I was getting into CRT refurbishments. It is a very scary project to tackle, if you know nothing about the subject.
Very cool. I have one of those, but It's been years since I've done anything to it. I didn't remember how easy it's to take apart. Many old CRTs are much trickier to disassemble.
thanks for your video. I've an ATARI SC1435 which has the same PCB mother board. And I trying to find the power on/off switch. But can't find it. And the TFT it's the same problem. Have you got any information where I can buy thoses parts ? Thanks for your help.
LOL, I actually made a discharge tool very similar to that for opening up an old imac. I honestly think it had long been discharged but hey, better safe than sorry.
I need one of those switches for my Olivetti PC, but there are a lot of similar ones and I can’t find the exact model, any suggestion on how to find a matching one?
Google image search all the numbers printed on it.
That’s the first thing I did 😄
It’s a Preh ME5C. Nobody on Earth seems to have it. What’s funny is that it’s supposed to have some low voltages pins, but mine only has the mains ones. Apart from that, it’s identical.
I need one of the same size to fit the lever that gies to the front of the PC. The switch itself is inside the PSU.
Now I wonder if a regular AT PSU has the same switch, but on cable. I must check my pile of salvaged parts...
Awesome video and explanation. I have e Philips Brilliance 107P, that powers up and the degauss kicks in, but there's no dispaly. Could that be the flyback as well?
Did you ever get round to fixing the one I sent you or was it beyond repair ?
It's in the queue Chris, I really want to fix it up when I can mate
What a great video. ASMR for the eyeballs. Thank you!
Thank you Will
The title of the video made it sound to me like you failed to fix the monitor, reading it again I realised it meant the Flyback had failed. I remember playing Space Ace and Dragon's Lair in the arcade back in the day.
RETROMANCAVE, what circuits in the monitor does the flyback supply? the flyback outputs many voltages but to which circuits? what circuits does the B+ voltage supply in the monitor?
Fantastic, I have the first version of this monitor. It is still working (I hope for a long time to come), I don't particularly want to work on one of those. Great video, thanks!
Superb monitors these i had one abot 8 to 10 years ago i sold it on ebay and got £30 for it back then i wish i had kept it .
I need to clean out my TV.. 40" beast. Pretty intimidating tube and charge, I haven't had the nerve to attempt a discharge. I opened it up a few months back to at least dust it with some canned air. Unbeknownst to me, removing the back kinda pulled the tray with the board out slightly and the right speaker unplugged as well as another that says CC. When I reassembled, I noticed the sound was out on the right side. Due to work, I hadn't fixed it until just yesterday when I opened it up again. The pins were bent slightly, so I had to bend'em back and then put the speaker and CC wires back into their slots. Then I took some up close photos of the board and looked at them on the PC. It's just layered in cat fur and dirt... Ugh, I dread discharging... I have the tools for it, screw driver, wire, alligator clip for the grounding braid.. but wonder.. can I stand on a wooden chair and attach the screw driver's handle to a PVC pipe and discharge from a distance?
Nice work sliding in your big tool to discharge! 😂 Seriously though, great as always man 👍
obviously you must have troubleshooted the set before.. to determine it was the flyback?.... about 80% of the time it is a power supply problem causing no high voltage ...
I picked one of these up recently for £50, but sadly it's missing the front flap. Bit of a longshot, but does anyone happen to have a spare front flap for the Philips CM8833 that you might sell or trade?
I have a bad 1084s d monitor, its powers up but the screen is dead, no static. I thought it might be the flyback but can't find one anywhere,
HR 46045 alternatives MSH-1FCT31/DCF1580 KFS60559/AM175714 ...
Can anyone help please
always wondered what the hisss was the monitor wouldn't come on, I went through so many monitors back in the day, PS I can print you off a screwdriver if you need one to tackle those other monitors to focus and brightness.
Just had a new Flyback put in. The tech said the old one looked totally fine and made connection, but thought he would put the new one in anyway and it worked.
12 hours of use and I’ve got the same problem again. What could it be? I gave him a HOT to change but he said it was reading fine
Great video pal! Just learned another lesson about repairing! Thanks for that! Cheers
Apart from the 1084s and MKII, which old CRT's (monitors or tv's) used the exact same component for flyback/LOPT ? How can I find out ? Buying a new flyback just seems too expensive relative to the cost of getting another monitor or removing an old flyback from another device.
Loved the video but the Space Ace clip really sealed the deal! subscribed!
One of my 12 Commodore CRTs, an 1084S that was working fine up until yesterday. I was working with no problems a week ago last time I used my A1200. Then yesterday nothing when I turned it on to play my newest Infocom game on my A1200. Well not nothing. 1. The red power light was not coming on at all. 2. I'm pretty sure I was getting high voltage because the 4 different times I tried I could hear the high pitch spin up when I turned it on and also could hear the wind down when I pressed the power switch to turn it off. I have many spare CRTs so I just swapped it out and played the game that I was looking forward to playing. I have watched a ton of CRT repair videos from you and many other Commodore & retro computer TH-camrs. This is not ringing any bells with the power light not coming on but the high voltage spinning up. Have you ever come across this?
FYI it looks like you've got some sort of interlacing problem with your video render. Every 2nd line is missing.
Hello. very good video. i orderd the hr7533 from ebay but my flyback transformer have 9 pins are there differns betwen MK1 and MK"
Ohhh wow amazing
My Trinatron Sony CRT stopped working 2 years ago, I turn it on it makes that sound, but no pictures.
Do you think I have the same problem ?
Its a 1980s TV (soon I'll get the model name)
Hi I am curious wondering if you could by chance help me fix my Philips crt tv? The model number that I have is 24PT6341/37. The problems I am having with the tv is the RF connector on the back has broken off. Secondly there is no sound on the tv either. The sound went out right after the RF connector broke off so I am unsure where the issue is as I am assuming that had something to do with the sound no longer working. Is there any way to fix the RF connector and the sound on the tv? Please let me know as soon as possible!
damn why every city has some CRT technicians except mine..I love CRT picture quality, unfortunally my most precious one died today and im kinda sad cause can´t find who can fix it..im actually starting to consider to learn electronic just to fix it and put a workshop exclusively for CRT repairings
sorry my english sucks I know
Link for the de-soldering gun? Just brilliant, best explanation and video on flyback very very nice.. Thank You.
Great video, something very satisfying about repairs like this :)
Hey man I have a question I would be happy if you answer because i am having a problem with this myself, I'm looking to replace the flyback for a CRT monitor and the only spare I got is from a broken CRT Tv do you think they would be compatible if I put the Tv flyback in the monitor's place?
Spent a full day replacing the flyback on my 1084S today. I initially thought it was a failure because I got either black screen or a white screen with pattern depending on my flyback screen adjustment. After seeing th-cam.com/users/gibs2b (TinyLauncher is the greatest) run into the same problem, I finally figured out that I had to do the screen adjustment with the power on because it has to be exactly tuned before it works at all. Fortunately on the 1084S the pots face the rear and are much easier to get at without risk of shorting. Whew! Oh, and now that the flyback is fixed, the power switch failed permanantly a few minutes later. XD
I had an old tv that had this problem, my dad and I could hear a high pitched noise, but my mom and sister could not.
Hi Hope you are ok. Just started watching you again. Was wondering have you bought a Lazerdisc player yet? If not I can give you some advice. Thanks
one of my 1084s is starting to squeal. do u think it needs a flyback replacement or to be recapped? and do u think i should stop using it until i get it looked at?
That little animation is great for helping to understand this.
What if it blips a little white dot, then shuts down immediately? This is a ~2000 zenith 25" I'm talking about.
I hear some later CRT models shut down when something is wrong, but I don't know if that would obfuscate whether or not it's a transformer or if that little blip means it's working or what...
Excellent video, do you ever do Cub repairs?
I have a working Cub for my beeb that I have had repaired a couple of times.... my concern for the future is that it is literally a dying art. A video on Cub maintenance would be very useful.
Cheers Peter
Thankfully I dont need videos telling me not to mess around with Flybacks because I already learnt that lesson as kid when I opened up a TV to see if I could fix it and tried cutting through the big thick wire going to the tube with a pair of metal scissors shortly after having turned the broken TV off and unplugging it.
Needless to day, getting zapped by 25,000 volts doesnt tickle (especially if you do it outside bare foot like an idiot)
