There's nothing like a good rescue, especially of a CRT! If my field found C64 has taught me anything, it's that old electronic devices are more robust and resilient than we used to think!
You're not wrong. It's pretty amazing due to the build quality of these old electronics. I wonder who made the CRT that David bought. When were the last CRT's made Adrian???
Always glad to see restoration from people which have a good heart to save those good old electronics, I feel warm that people still spend time to rescue the electronics from the landfill, in my city they're sure going to trash bin and will tear down and scrape for copper, old computers and monitors much more memories from childhood.
Analog electronics which is what comprised alot of electronics back then are far more durable then micro electronics. its why a big hard wired radio is stupidly tough and resistant but heavy, big, and expensive. But a micro electronics small and light radio brakes if in the wrong condition. And its simply because all the electronics are all hard wired because its all analog operated and not digital. It just boils into they don't build em like they used to because people would prefer convenient cheaper electronic over durability because its far cheaper to replace them then repair them unfortunately.
Quite an unfortunate twist in irony, electronics back then were durable as hell but treated with excessive caution, modern electronics are way more delicate but not always treated the best.
Interestingly, with the Machintosh TV (the 90s one), they used a Sony Trinitron CRT. But, if you look at the others similar to it (the LC 500 series, for example), they don't mention that they use that. So, they could be using Samsung displays in these machines, actually. Not really too sure, though.
@@KorbenTheFireX Trinitron tubes are very easy to identify by their shape. They only curve side to side, while shadow masks curve both side to side and top to bottom. Also, if you look closely, Trinitrons have the 3 phosphorus cells side by side while shadow masks have them in a triangle. The problem with this method is that after 1997 when the original patents expired, there were many fake Trinitrons. Apple even has used many fakes in its products. Also, if its a later model and its flat, it could be either an FD Trinitron, a fake FD Trinitron, or a flat shadow mask. Either way, to get the best possible picture quality go for a Trinitron tube that's actually part of a Sony device: a TV, a generic monitor or a VAIO monitor. They may even have Digital Reality Creation or WEGA engine that way.
Lets all take some time to recognize that this monitor was sitting outside in minus 8 degrees F temps during the Texas mega storm we went through back in February, yet it still powers on.
step one figure out what the diode was step two get a modern replacement to repair the monitor's by putting the new replacement in it to get it working again

I agree, Nice find. Do you get to keep it or are you fixing it for someone else to eventually buy it? If you have a way to do so you should cast a copy of the front knob panel so that you can make a replacement, maybe with a better hinge.
dude you left your monitor out in the rain for 20 years and somebody found it and took it to computer reset where the 8-bit guy took it home to clean and restore it

Good heavens, now THERE's a throwback reference! Was equally more surprised to see the site's still online today. Would've thought they faded into obscurity.
That component behind T3 looks like it's a spark gap, which is designed to protect against overvoltage. Your high voltage regulation is defective, which is what is causing the HV to run away, blowing out the picture before arcing and then coming back. The pattern of dim, bright, arc, dim, bright, arc is a bit of a giveaway on that. If it was an actual diode then it must have been the damper diode since that's in the HV circuit.
some of the connection points on the underside of the board look if not corroded at least in need of clean I suspect voltage is jumping, leaking and at least another component gone u/s (or a trace). Buy at least 3x as many diodes as you might need, as one might blow before you have noted what is going on
It's the rectifier for one of the flyback secondaries, I believe. It's possible the rail it supplies is sampled and used to control the HV, but on the other hand the failing diode could just be causing the problems in other ways.
they had many more of the monitors in various conditions in the inside of the warehouse, none of them worked unfortunately but i spotted a few rarities that were a shame to see in such a state
@@RCAvhstape: I have been subscribed to his channel, but thank you. Don't forget that Tim himself encourages downloading of TSLOM episodes (sciencezero.4hv website).
Hi David. Tv technician here. Almost in any tv when it has retrace lines and white screen means a problem on 180V video line, and sure enough that diode is shot. You can use any fast recovery diode in this case 1A and 600v or more, like FR107, UF4007, BY227, RGP10J... those are mostly used in many tv chassis. You also need to change the electrolytic cap on that 180v line because the diode turns more like a resistor. Must be really good electrolitycs but always is better to change all caps in PSU and vertical deflection circuit wich are the most prone to fail. A similar failure with retrace lines but with image (instead of a white one) is generated by a faulty ceramic cap filtering screen voltage. Greetings from Argentina.
I thought you said, "If there were cat juice it would be sticky" and all I could think was, "Yeah and probably smell pretty horrible every time it got warm!"
8:21 Now I feel stupid. Every time someone said or wrote "A-Hole" i assumed it was an insult. They just meant "Anode-Hole" and were talking about CRT monitors. Now I get it!
The hot Texas climate surely has helped preserving this allowing the monitor to dry after it got wet. If it wouldent be able to dry it would rust away on the inside very quickly.
Yes. And what it was exposed to was only relatively clean rain water, dust and leaves. That's actually not even close to the conditions in a landfill, where it generally would be exposed to crushing force (proper landfills are usually compacted), juices from decomposing organic matter, a lot more salts and acids etc.
I hope someone writes a book about Computer Reset. Such a cool place that (seems to?) have fallen into the right hands. Hope more "Computer Resets" are out there waiting to be discovered and ro have their contents preserved.

There is a nonprofit company called free Geek and they basically take in used PCs and help refurbish them and donate them to needy people or sell them at very affordable prices to the public.

Back in the mid-eighties, my dad, bought a disk drive for the Apple /// computer from the fellow that ran Computer Reset at the Infomart computer flea market in Dallas, Texas. It was strange, because it came in a Disk II housing, but it was for the ///. Anyway, they had a BBS back then that I signed into once or twice, but when the video surfaced of the place, and especially the logo, my memories of them came back.
Just a minor heads up: for pots, you’re probably better off using deoxit fader lube instead of straight cleaner. That way you can add back whatever lube was lost in the cleaning process. Helpful tip I learned from servicing guitar amps.
That's a great idea. I ordered the D5 for motherboards, ports, and a few items along with the F5 FaderLube for the potentiometers since my Kawasho Color TV/Radio/Alarm Clock/Auto-outlet set is jumpy.
Wait, I missed some kind of context here. What was this building where people were just throwing computer parts in an alley? They weren't even putting them in the trash, what is going on?

And finally the creators that stretch out their content in episodes to increase revenue that way.
7:30 It's probably already discharged since its been a couple days... NO!!! A CRT can remain charged for years and even one that has been discharged can spontaneously build an impressive charge under the right circumstances. ALWAYS discharge the tube before handling unless you really like pain.
Normally, that would be a protection diode. It saves the circuit in a reverse current condition. In this case though, it’s more likely acting as a rectifier. Same basic function but different use case. Rectifier failure would cause the current to flip + to - at 60hz. That looks about right for what that screen was doing.
Usually your posts show up at the top of my browse screen, but nothing this time. Glad I randomly checked your channel! Awesome work as always. Love these rescue projects.
Just a suggestion for future cleaning projects, a set of car detail brushes would really help getting into the small places where dirt likes to go! Keep up the great work and great content! I hope things are improving in Texas!
"if I can make this work and look like new again, then that means that there is hope for the millions of other computers..." Now, the only thing we need is just several thousands of 8-bit guys
That diode seems to me like a regular high frequency SMPS diode. Most likely an general purpose replacement will be sufficient as long as it can handle the frequency (15khz) and the voltage (most likely 180V).
You have an issue with flyback blanking too. Try not to leave it on for very long after changing the High voltage diode, or you’ll have the lines forever on that crt. Lookup the fly back blanking circuit in the service manual for it and you should easily find the cap that causes your fly back issue.
Lovely video! First time using headphones while watching your videos. Noticed a small shift in stereo/“mono“ when there was audio from your studio(2:31). Just wanted to let you know. Thanks for another awesome video👌
Apple IIs were a huge part of my childhood computing days (though I think I was more used to the monochrome green ones) so this repair attempt was neat to see!
I’ve dumped most of the Apple ][ stuff you have discussed in your videos. Like the special breakout cable for the Apple II card for the Mac. I have a Macintosh XL but not a compatible keyboard. So hard to keep all the tech straight after so many generations. It’s always great to see how well you get these old generations to work. Your videos along with another TH-camr who built a working 6502 computer on a breadboard has really made me want to go back to my 8 bit roots! Thank you.
Wow, you are incredible. I know it is simply the training you have vs what I was educated as, but this was really impressive. Particularly the did problem. Hope your home has recovered from the disaster. Glad to see you back.
8-bit Guy: "After removing all the screws it still didn't want to come apart" me: (imagining a giant spider with half its legs holding the top, half the legs holding the bottom, and pulling the monitor back closed when it starts coming apart)
Can we please have a few moments of silence in gratitude for the many generations of spiders whose tireless efforts over the years have prevented this monitor from turning into a roach farm. Thank you.
Wow, that's an ultra-rare monitor! The RGB model (plus the required RGB 80 column card) added so much cost to the Apple //e that very few owners bothered...I used the RF modulator I bought at RadioShack for the times that I wanted color. Never did the need for color + 80 columns ever pop up 😉 Judging by the quantity and apparent inventory stickers, I'm guessing school district or private school. The El Paso Independent school district made use of monochrome monitors on their Apple //e's . Nice to see you back on YT, David!
yeah that brush he took your tooth brush and used it to clean that monitor sorry buddy your going to need a new tooth brush now but it was in the name of saving and old classic monitor
Small, relatively soft nylon scrubbing brushes in round and angled configurations are absolutely ideal to have when scrubbing really filthy electronics, among other things. You want them to be just stiff enough that they will offer some motivation for the dirt and grime but not so stiff that they actually scratch the plastic. Some of the cheap nylon brushes that come with packs of wire brushes can actually still be hard enough to scratch the aged plastic on old electronics. Best to start with brushes for cleaning dishes. I'm always amazed at the persistence of old electronics. Some of them will just keep working even when they've been so thoroughly neglected that you couldn't imagine them possibly ever working again.
There's nothing like a good rescue, especially of a CRT! If my field found C64 has taught me anything, it's that old electronic devices are more robust and resilient than we used to think!

Better yet: Always discharge EVERYTHING. I've been bitten twice by a digital camera. Not fun. Don't mess with that. Don't be stupid like me
@@chiaraj1003 Yes! Electronics with large capacitors can stay charged for quite a while. Got bitten by a disposable camera once.
I just can't wrap my brain around the fact that they sat outside in texas for years and they still work. I'm in complete awe.
A new video, you just made my day!
Correction:you just made everyone's day.
Wow didn't expect to see you here, thanks again for all the 5.4 3v help !
More like a new Windex(tm) commercial....
Not only that but it's a restauration video.
Yes
Normally, that would be a protection diode. It saves the circuit in a reverse current condition. In this case though, it’s more likely acting as a rectifier. Same basic function but different use case. Rectifier failure would cause the current to flip + to - at 60hz. That looks about right for what that screen was doing.
W8 but correct me if i am wrong doesn't this work on dc? Dc has no frequency though?
Its a zener clamping diode in an ancient style casing.
This should be required reading for anyone starting in electronics restoration. Thank you for the information and entertainment. Cheers from Austin.
Usually your posts show up at the top of my browse screen, but nothing this time. Glad I randomly checked your channel! Awesome work as always. Love these rescue projects.
Oh a cliffhanger episode! I'm looking forward to Part 2.
The fact the monitors still working after decades on the outside buries me. I mean i just 18 years old and already broken
@@araigumakiruno lol it gets worse. Source 28 year old
Just a suggestion for future cleaning projects, a set of car detail brushes would really help getting into the small places where dirt likes to go!
Keep up the great work and great content! I hope things are improving in Texas!
Strapping in a CRT. This guy is so unintentionally funny that it always makes my day a little better.
"if I can make this work and look like new again, then that means that there is hope for the millions of other computers..."
Now, the only thing we need is just several thousands of 8-bit guys
That diode seems to me like a regular high frequency SMPS diode. Most likely an general purpose replacement will be sufficient as long as it can handle the frequency (15khz) and the voltage (most likely 180V).
Ultrafast rectifier
I love these types of episodes, they even end on a cliff-hanger.
Little bit of extra electronic-forensics in this one
Awesome find cant wait for part 2. Would love to see more of these, like dumpster finds that you restore.
Another awesome video David! Can’t wait for episode 2!!! 😃
Watching you clean old electronics to upbeat synth music is very comforting to me.
The best part about The 8-Bit Guy series is that we get another video(s), the bad part is that we have to wait for it.
I love how you do these repair videos. Excellent work.
man, I missed you so much and your videos, I'll wait for that second part! Love Ángel.
How come that I just ate 15 mins of this and I’m craving for part 2. You’re a master in creating intrigue😄
Gotta admit I laughed when the diode fell off and just pulverized itself.
Me too!
13:10 Let see if he gets lucky with those electrolytics
Love how thorough you are.
Grrrr! Got me all excited about the repair and now I have to wait for part 2. Great vid by the way! :)
You have an issue with flyback blanking too. Try not to leave it on for very long after changing the High voltage diode, or you’ll have the lines forever on that crt. Lookup the fly back blanking circuit in the service manual for it and you should easily find the cap that causes your fly back issue.
good video but the diode is a fast switching high voltage diode.
I suspect the diode you referenced as a replacement probably wont work
Lovely video!
First time using headphones while watching your videos. Noticed a small shift in stereo/“mono“ when there was audio from your studio(2:31). Just wanted to let you know. Thanks for another awesome video👌
Good job as always! Wish the video was longer! Keep up the great work!
Thank you. I was craving for another one of your restorations, of course with Anders Enger Jensen music in the background. That is sooo satisfying.
“And since it’s mostly clean, I’m not going to worry about it.”
*hundreds of jaws drop*
I really expected a trip to the car wash and a pressure wand there.
IKR?!
It'll probably get a more detailed cleaning when he goes to retr0bright it.
i can hear AMMO NYC screaming even if i live in Europe....
@@flounder31 He should really invest in one of those (pressure washer), when you mention it. It'd be useful and satisfying to watch.
Thanks 8 bit, this channel is fantastic!
Watching this kind of videos is like watching electronic history uncovered
Welcome back! You are by far my favorite TH-camr, I’m so glad your family seems to have survived the strange weather this year.
You and LGR releasing monitor videos on the same day? Perfection.
...running to see LGR's. Too good to be true.
@@RodrigoVivanco Me too! Why didn't LGR show up in my feed? *need to see*
@@andreasklindt7144 It's on LGR Blerbs, the second channel not main one
It's a double feature: *LGR* covers IBM, *The iBook Guy* covers Apple.
@@Christopher-N LGR covers pre-Doom stuff and former iBook Guy deals with early Apple, so not quite in their supposed comfort timezone, right?
Im loving the video. The vibe. And the jean shorts. You just unlocked memories
I love that you strapped in the CRT with a seatbelt lol I do that with fast food bags, and when transporting desktop towers.
I love these types of videos. My favourite is the one where you mod an old CRT TV to accept RGB input.
Hart warming and environmentally sound!
How they turned the place from last chance to a salvage project is amazing! :)
Woo! Can't wait for part 2. Awesome video as always! Thank you for all your hard work.
Good to see your show is back. I hope your home is on the mend.
So happy you are putting out new content. Hope you are getting back into a regular weekly routine for videos
Audio in the studio sounds great! Btw do you have a new camera? (I know you use over head device for the audio)
03:20 this was a Hitchcock level of tension I was fully expecting the monitor to catch fire
Hey David! I love your restoration videos!!
Apple IIs were a huge part of my childhood computing days (though I think I was more used to the monochrome green ones) so this repair attempt was neat to see!
"And over here we have the wild Monitor, resting with the rest of its pack."
*its (not "it's")
@@JohnDlugosz I’m actually quite the grammar nitpick myself, kind of strange how I didn’t pick up on this earlier. Thanks.
I’ve dumped most of the Apple ][ stuff you have discussed in your videos. Like the special breakout cable for the Apple II card for the Mac. I have a Macintosh XL but not a compatible keyboard. So hard to keep all the tech straight after so many generations. It’s always great to see how well you get these old generations to work. Your videos along with another TH-camr who built a working 6502 computer on a breadboard has really made me want to go back to my 8 bit roots! Thank you.
Wow, you are incredible. I know it is simply the training you have vs what I was educated as, but this was really impressive. Particularly the did problem.
Hope your home has recovered from the disaster. Glad to see you back.
So pro tip: store your monitors facing down if you put them in a landfill?
You typically wouldn't do that as it can cause problems with certain ones (I think, don't quote me on it).
Probably up would be better.
@@bertsimpsan Whoops, sorry. That's why I said "I think, Don't quote me on it" too.
@@bertsimpsan Relax dude. He already apologised and you're still flipping your shit over something that wasn't a big deal in the first place.
8-bit Guy: "After removing all the screws it still didn't want to come apart"
me: (imagining a giant spider with half its legs holding the top, half the legs holding the bottom, and pulling the monitor back closed when it starts coming apart)
Basically 99% of tech in Australia has spiders in it when you open it. I opened 6 old school computers, they all had spiders in them.
I didn't think of spiders, per say, but I did think that he was going to find some kind of an animal in there.
That thought is genuinely terrifying. 😱
The original web crawler. :P
So basically, always inject bug spray into an old device and wait about ten minutes before opening lest you suffer the horror.
I like your cleaning and restoring videos a lot. Soo satisfying! Good work!
Very glad your back my friend
Always refreshing to see a legitimate restoration
Can we please have a few moments of silence in gratitude for the many generations of spiders whose tireless efforts over the years have prevented this monitor from turning into a roach farm. Thank you.
First series since being subscribed so I'm excited to see this
YAY! A new 8-bit guy repair video :D. Long time coming baby :)
Love the Apple ][ content!! Can't wait for part 2!!!
I can just imagine you looking around for the diode: "here diode diode... here diode"
And it not being an smd...
Wow, that's an ultra-rare monitor! The RGB model (plus the required RGB 80 column card) added so much cost to the Apple //e that very few owners bothered...I used the RF modulator I bought at RadioShack for the times that I wanted color. Never did the need for color + 80 columns ever pop up 😉 Judging by the quantity and apparent inventory stickers, I'm guessing school district or private school. The El Paso Independent school district made use of monochrome monitors on their Apple //e's . Nice to see you back on YT, David!
Loved this video. right up my street! Also the Musac througout was very good / appropriate.
"I'm not even sure what that is supposed to be"
Me: "Oh, that's a diode"
a few seconds later in the video "I discovered that it was a diode"
: D
Fun fact: apples begin their life cycle as junk.
This is the old school type 8bg I've been waiting for. Thank you
I love that you asked Adrian for help with this. The best of retro-YT getting together LUL
I think whenever the 8-Bit Guy finds tech in a landfill he has to restore it. This is quality content.
yeah that brush he took your tooth brush and used it to clean that monitor sorry buddy your going to need a new tooth brush now but it was in the name of saving and old classic monitor
that music totally captures the era even though it’s not OF the era. great job.
Its been over a year since the last video completely dedicated to a restoration thank you i love the restorations
Small, relatively soft nylon scrubbing brushes in round and angled configurations are absolutely ideal to have when scrubbing really filthy electronics, among other things. You want them to be just stiff enough that they will offer some motivation for the dirt and grime but not so stiff that they actually scratch the plastic. Some of the cheap nylon brushes that come with packs of wire brushes can actually still be hard enough to scratch the aged plastic on old electronics. Best to start with brushes for cleaning dishes.
I'm always amazed at the persistence of old electronics. Some of them will just keep working even when they've been so thoroughly neglected that you couldn't imagine them possibly ever working again.
