- Scrubbing down and starting up a 1980s EGA monitor from IBM! Just a relaxing, laid-back restoration video. Well, not a complete restore, it'll absolutely still need work but y'know. Blerbs.
TH-cam whyyyyy. I uploaded this as a 4K 60Mbps video, same as everything else I make.
Yet it seems to have been _mangled_ by compression, ugh. Here's a better quality version: archive.org/details/lgr-blerbs-cleaning-and-testing-an-ibm-5154-crt-monitor
Wow. Thanks for this. Really neat seeing the pre-upload quality.
watched in 360p :)
TH-cam is to busy kicking people off and demonetizing people they hate… why run the future of broadcasting.. it’s all about politics and payola for garbage that is on normal tv.
Play centurion from ea its ega and fun to play
The flybacks on these have a focus and brightness adjustment on them. Clean all the dust and check for leaks in caps but most of all de-oxit the adjustment POTs. Also mark the flyback adjustments and while off rotate the adjustments back and forth a few times. It will scrape off the corrosion and should fix the issue.
Wow Clint can really move his hands fast
The ladies love him.
Years of training.
haha brush go brrr
Nah, that's just "cinematic FPS"

@@BlueCollarBachelor well it's not contaminated with living bacteria, but that doesn't mean it's not contaminated with things that aren't alcohol or water. I stopped dipping things in the bottle once I noticed it was apparently dissolving something in qtips that left a white residue after use.
Well today is apparently the national CRT plastic cleaning day over at the States.
Doesn't look like there is one. Should be.
Yeah, the 8 bit guy fixed up one from outside of that old computer shop, I'm amazed any CRT would survive being rained on and buried for several years on end.
when Clint says "what do you know dude!" I feel like he is talking directly to me.
Lol I read this comment and was wondering when he said this. Then he flipped the monitor over. Lol crazy timing.
When you get home from work and Clint uploads within 15 minutes, you put your chores on hold.
you must be in the UK

@@cydragon2.099 I'd do anything to get off of night shift right now. Unfortunately not possible in my current financial situation, but as soon as it is, I'll gladly take the pay cut and go back to days.
@@geoffreyreuther5260 well for me since I do enjoy the Night-Time I've been wondering to take it on
Both you and The 8-Bit Guy uploaded a video about old and disgusting CRT's today! It's like I ordered a slice of cake and got 2.
Yea that made me laugh, that LGR and 8-Bit both were on monitor cleaning, though sadly no joy with 8-bits monitor restore have to wait for pt2
Caps seem like the biggest target to go after considering the dimming occurred right before your eyes. So see if there's a cap replacement kit online to do it (kinda like you can get for gaming cabinets).
Or he could just order the caps if there is no kit. It just takes a bit more time
@SteelRodent The only thing there is that the contrast would make white text glow really friggin bright, so the phosphors seem fine as does the electron gun, also and this is just speculation, it would seem like the phosphors would dim at different levels, like we saw it going dim on pharaohs tomb which had a lot of black space, but when he opened edit it was uniformly dim, which doesn't seem like it would be the phosphors, it seems like it would be capacitor related or something in the circuit for total brightness< i had a gateway 2000 monitor that would do that after 10 minutes it would end up really dim, but letting it cool down and turning it back on again it would be fine for another 10, i just scatter shot a load of new caps, and some other components that looked dodgy and it fixed itself and has be perfect since
@@compzac Holy crap, I have a Gateway 2000 monitor right now on my 486 that's doing the exact same thing (Vivitron). I'll have to give that a try on it because besides the dimming, it's a great monitor.
@@shamrice yea couldn't hurt to try, I've had a few electronics that would last and work fine for a short time then go off or act odd, but just letting them cool would get them back up, usually it was capacitors or circuit chips, but with my monitor it was just caps
Fly back Voltage cap is where I would start
Almost certainly needs a recap.

You could also just retouch the chips and dings. At least in 2018 there was a guy on fleaBay that sold re-touch paint pens with the IBM paint code.
Watching a video of Clint cleaning a monitor is weirdly relaxing.
I don't even watch these videos i just treat it like background music while I work.
Maybe there should be an LGR Cleans channel! It is relaxing.
Don’t you mean the mon-it-or?
"The longer its turned on, the dimmer it gets." True for monitors and men
Why is hearing you scrub at a million miles per hour so satisfying?
`This was my first PC monitor, My dad took it and a 286 from a skip outside his offices in the early 90s, He took home 4. I was 12 and it took me weeks, but I got one working... that was my machine until I lept to a 486.
Those were the days
These restoration videos you do are pure comfort food
(19:06) You also turned me on to those Scotch brand felt dots, too! I got a coupled of variety packs and they've come in very handy! :) I have so many pieces of stereo equipment (mostly) that have been marred by screws and whatnot from the thing sitting on top of them. Wish I had found them sooner! :/
Adrian's Digital Basement collaboration??
Hopefully, it just needs some new caps and a tune-up.
my thoughts exactly.
Dr. Adrian will consult with you on this patient.
That boot-up sound with the slowly accelerating hard drive and the floppy drive seeking instantly brought me 30 years back in time! Thank you, Clint! My past self would like to remind you: Earlier DOS versions use less RAM and may get you your 590 KBytes. DOS 5.0 is a little new for this machine. :)
I agree Clint we need to save as many of these old monitors and crt TV 📺 as possible
24" Sony CRT TV stored next to my bed supposedly for a retro set-up I will be running some time in the future, or who knows, even later in the future??? :)
@@Jamal_Tyrone as long as you don't throw the crt away its all good. It took me 5 years to get my first retro console setup
I had a neat monochrome "color" monitor in the 80s. It was only color in that you could press a button and select white, green, or amber monochrome modes.
It was the same monitor I have started to learn about PCs back in 1994... So nice to see one restored.
You wouldn't have seen it brighter if the CRT itself was worn out. Most likely some caps warmed up from your use and their ESR went way out of spec. Definitely just get in there and look for bad caps visually and find which caps are related to the issues you're seeing in the schematic.
God I love getting old electronics from the thrit store and cleaning them up like this thanks to you!
Definitely caps. As the machine warms up the caps will change values. This causes all sorts of strange issues like brightness.
I kept thinking you missed a spot and the realized I need to clean my own monitor.
(15:51) Those little plastic razor blades are awesome for getting stuff off without marring the surface! I actually got one after you showed it before and use it a LOT! :) For those not in the know, it's a Titan Plastic Razor Scraper. You can get one plus a pack of 25 replacement blades for a little over 8 bucks on Amazon. :)
Goal in life: find somebody who cares about you with the same passion Clint takes care of his retro stuff. Weird things come to one's mind after watching 10+ minutes of high speed scrubs.
Nothing more relaxing than drinking a mate and watching you clean a CRT.
I'm assuming you meant "latte"? Not trying to be that guy, maybe I just don't know what a mate is other than a linux flavor :p

Must be monitor restoration day! 8bitguy just uploaded pt1 of an apple ii monitor resto!
If you plan on repainting it I think you should sand all the surfaces before painting and don't forget to apply some sort of grease removing stuff so the paint sticks better.
8:10 - I think you can replace that connector, there are still metal D-SUB shells out there, or at least you can replace the missing screw in that original connector shell from a new shell.
Too free up some memory, prevent the machine from loading the CDROM driver :)
I like clean white restored plastic, not long ago I built a UV LED strip "chamber" that runs on 12V, sprayed the inside of a box with chrome paint to reflect more light and stuck 2 mirrors on the bottom and lid too. I can retrobrite stuff in 24 hours and since it's closed it doesn't damage anything in my room and don't need good weather for retrobriting. I did some old PC speakers and a couple of front bezels of floppy and CDROM drives. It just feels better to look at them :) I'm planning to do my Amiga 500 soon too.
Watching two videos of guys cleaning monitors is mentally relaxing.
Bask in the irradiating glory of this screen! 🤘
Always in for a good time when the rubber gloves come out.
If you want to disable an item in autoexec.bat, you could always REM out the line instead of deleting the line. :)
Best video of a guy cleaning a monitor, ever
Wow that groove was dirty. Glad you got deep in there.
I have one huge IBM CRT left, had it since the 90's, it's the size of a TV, in perfect working order. One day I will make use of it again!
Watching this made me actually clean my own laptop screen....for a change!
This would be on LGR of like 10 years ago, and now we get this half an hour goodness as a bonus on your second channel ! So awesome !
Very cool 👍
I recently cleaned/restored our old SNES controllers the insides were sooo gross!
They look great like new condition and more importantly the buttons feel good
I would guess the capacitors for the PSU are probably dryer than a carcass in the desert. Probably worth replacing those first if you are comfortable working inside a CRT with high voltages. You can get a cheap ESR tester off eBay if you want to check the individual capacitors ESR reading against an ESR chart just to see how knackered each one is🖥️🖥️🖥️
Given deflection is steady I doubt capacitors in the main PSU are causing this problem. AFAIK failing electrolytics tend to improve in ESR when they warm up. I'd bet something else is causing a misbias in some of the analog signal circuitry.
@@eDoc2020 True but I've also witnessed knackered old electrolytic capacitors with high ESR reading get that hot after they are left powered on for the first time in decades that they spew the remaining electrolyte out onto the PCB which is what I'm wandering has happened here.
No doubt we'll all find out what the root cause is in due course👍🏻
I agree with sabretooth, sorta i doubt the PSU is the main issue the monitor seems relatively fine aside from the brightness, i would guess that its the caps, plus from my experience with 80s electronics a lot of times they get wonky from caps, i had a Sony Television that would work fine for 10 minutes then the picture would just disappear, the Tv would still be on youd hear it through the speakers and it would be tuned into a channel or running an input source, but no picture, turns out it was aged capacitors, also fixed my quiet audio and same issue this monitor had where the sub brightness was kinda dark.
Speaking of nasty grooves, when are you going to start the LGR Synth channel?
I had this monitor back in 1991. Was a hand-me-down, but my first computer monitor as a kid.
I *loved* Pharaoh's Tomb on my Tandy 1000 TL/2. Definitely a trip down memory lane to see it again!
Finally another cleaning video!
This was nice and chill somewhat in the background :)
Reminds me of when I worked at Kmart in the late 2000s and we were still using a similar monitor for our inventory system and it was obvious nobody ever cleaned it, sat in a hot warehouse for 20 something years getting poked at with filthy hands.
This is a TREMENDOUS day for crt restoration vids, with 8-Bit Guy's and Clint's videos. And I'm a crt nerd soooo...
I am so glad CRT nerds exist, because I genuinely believed they would be the one piece of retro tech nobody would have nostalgia for. Not sure what I was thinking, when clearly that is actually "IRQ conflicts"
Reminds me of what happened to a similar IBM monitor Tech Tangents was working on. One of the color channels just kept getting dimmer and dimmer until a cap blew.
Big white chunky monitor from the early 80's? YEEEEEEEEEEEESSSSSSS!!!!!!
What better way to spend time monitor shopping than to watch a video about a fixing a monitor.
Love the sped up sounds.
PRPRPRPPRPRPRPRPPR
nice and clean
I had a nice ibm crt back in 1999 that I got from a local small computer store. I traded an ast pc for it and the monitor was awesome. It was used by Ford.
It seems it CRT month on retro tech channels, David has his landfill Apple CRT, Adrian was working on a trashy CRT last week and now you are dealing with a CRT :)
Every month is CRT month 👍
If it's CRT month maybe I should try and get my Dell 21" CRT monitor working again...only issue is it weighs 70lbs and I have to carry it up two flights of stairs

@@Dukefazon cheers
I used to have one of these at home, got it for free from my old job back then. I loved it! Great to see this model again.
There is something very satisfying watching the monitor becoming clean.
If you want to avoid painting the whole thing, there are paint kits you can get for colour matching. There is definitely a bit of a learning curve, but with practise you can touch things up and even match textures to an extent. Definitely a skill worth developing if you care about restoring stuff.
This is like old computer ASMR
I just got my CRT monitor and Model M keyboard Today for my windows 98 build and, thank you for showing me Model M keyboards because it is the best typing experience I have EVER HAD! I'm typing this comment on my Model M right now, probably not the best video to post this comment because the video has nothing to do with Model M keyboards but whatever I love my Model M keyboard! Oh ya and the CRT Monitor Was fine as well.
that woodgrain table has been through a lot lol. Poor thing.
A work table being used for work every day.
I'd say it's living its best life 👍
Very cool! i just got a IBM P200 20 inch crt monitor my self from 1995. It takes a while to turn on but once it warms up it works pretty good! gotta make a video of it still. lol
A 5154 - nice! Would love one of these for my 5150 so I can take advantage of all of those EGA modes. Although to be fair the 5153 paired with an IBM EGA card covers pretty much everything I need. 😄
I want one of these too for my AT ive got an amdek for it which i love, but its a slightly different aesthetic and i like IBM stuff, plus i have a Compaq that the amdek goes much better with
I legit remember when you uploaded this type of video to the main channel. Those were the days *daydreams*
Wow, it's incredible how easy it is to tell that those knobs are far more practised than the ones on that other monitor
"Replacing caps on an IBM 5154" video next? :)
The fast forward is just so satisfying! ☺️
Open that bad boy up Clint!!! Just cleaning the outside aint nothing!
Instant trip to the past! The 5154 was the monitor on the first computer I saved up for and bought myself (at 13). It was a scrounged-together system. IBM monitor. Generic case labeled by a local PC shop (I don't even remember which one at this point). 286 SX chip. MFM hard drives... ohh, yeah! Manually park them heads, baby!
Sounds like the voltage regulator for the crt heater is going out of spec after warming up. If it's unable to maintain the tube temp, it will cause the monitor to dim. That isn't something a hobbyist would be poking around in there to fix, though.
CRT troubleshooting & rejuvenation collab with Adrian?
Can't beat a good monitor restoration, bringing CRTs back to life is fun... :)
A true unicorn in retro land.
I have an old IBM VGA monitor just a few years newer than that thing and a lot of the adjustments are potentiometers that are mostly a paint to get to. That means adjusting them while the thing is running. Not for the faint of heart! LOL
Beautiful monitor, Clint! The items you buy/receive never cease to amaze me.
Everything leads back to capacitors. I've noticed that at times too. I had a Zenith Supersport SX (Crap machine, despite the 386 and VGA capabilities), and everything seemed to come back to full brightness when I changed the capacitors.
When you speed up the cleaning for the video that is sooooo satisfying lol awesome blerb!
yeah that definitely seems like something that could be capacitors going bad, but I'm not super sure. High-voltage AC is dark magic.
Blerps turned into my favorite "watch while cooking or cleaning dishes" videos.
i love these cleaning and restoration videos of yours so much
"Who's jamming to my nasty groove?"
Somehow it’s “restoring old monitors day” on my vintage computing people TH-cam stream. Between this, and Adrian and Dave’s Apple screens.
I think I've reached the point where I'll just watch anything you upload, Clint.
One of the things from the 80s and 90s I don´t miss are CRTs. Need lots of space, have a bad picture and consuming way too much energy.
Only advance was, that my cats loved to sleep on top of them, because it was warm up there. Try that with a flatscreen. ^^
you need to replace the transistor. When transistor ages it looses gain when it gets warm. Same thing happened to me once before most likely this is the power portion of the circuit (not signal transistors). So check transistors with high current the ones with more than 100mA. It will be easy to find because they usually have a slight burn around the PCB,
Hey Clint! It‘s defenitly the caps failing there.
Look at minuszerodegrees- there‘s dome information about that monitor. ;)
Pretty sure it's the phosphorous layer. The tube may suffer from some oxidization from bad vacuum during production but those are very rare, and if there were a leak it wouldn't work at all by now.
I love cleaning! Oh yeah!
It's a shame that the monitor gets dim, but nevertheless it's better than if it didn't work at all!
Thanks! =)
Gotta love 80s aesthetics.
LGR and 8 Bit Guy hitting me with monitor restorations on the same day gave me heart palpitations.
Amazing 20min. Of cleaning 😆
It's plastic so you could probably fill the gouges with putty like people use in plastic models. Then sand the spots down a bit and paint over them.
Late to the comment party. But, based on experience this is either a cap issue or the flyback itself. I've seen both do this to arcade cabs. Do a re-cap first, if that doesn't have an impact on it, then the flyback is likely toast. Starts out fine when cool, but as it warms up the brightness and focus controls start drifting. Good luck!
"decades old finger juice"
...I really need to stop watching these vids while I'm eating
Looks like you'll be replacing capacitors soon! I managed to repair mine after it let off the magical smoke, but it only reliably works in CGA mode until it warms up, then EGA works fine (I have it connected to my 5155 with a modified IBM EGA card that allows the internal monitor to still work when in CGA mode - a small program changes the mode). I have a few more capacitors to replace to fix that issue. I created 3D printed feet for this monitor (because of course I did), but the replacements you have look like a really good fit!
Magic Eraser gets the grime and crap out of those old CRT monitors pretty quickly.
It's my birthday, I melt the candles in the B'cake waiting for both Clint and Dave....
Oh no, alcohol-soluble paint!
That's actually why my Nintendo doesn't have the 1 and 2 labels on the controller ports anymore. I was cleaning the poor little thing up, making it a bit less grungy and scuffed. Cleanin' dirt off with alcohol. Take a paper towel, swipe across the controller port section, and the paper towel comes away with two bright red streaks on it.
"no puffs of smoke yet, that's a good sign".....lmao
Clint, you should really get someone who makes cleaning kits to sponsor videos like this.
Considering how much I avoid sponsorships and generally find them off-putting, I find it strange whenever folks actively ask for them. Perhaps I'm the weird one though :P
@@LGRBlerbs I think there's a massive difference between sponsors that are unrelated to the show and the ones that are actually relevant to the topic.
