Thanks Adrian! I guess I need to thank your many CRT repair videos if I decided to work on one myself! Sad indeed that I couldn’t get a fully working one. Thanks for watching!
@@tony359 LG was originally actually branded as Lucky Goldstar. I think its similar to Sony, which I beleived was meant to be Sunny and of course the infamous Donkey Kong, which was meant to be Monkey Kong. Literally lost in translation. By the 90s, Luck Goldstar probably felt their name was maybe a little twee, so retired the Lucky part, as I recall, using Goldstar for a while. But then reduced that down to LG...
Going back to your native language when things go wrong is pretty normal😁 The tube might have been the reason for the RMA in the first place and the other issues secondary but who knows. Thanks for another interesting and entertaining video.
ahah - yes, that was an interesting moment LOL! I have a feeling those monitors were made of "bad parts" and returned to the factory for refurbishment. So LG would open up a monitor where nothing works, basically boxes full of broken parts. Who knows. I haven't collected the rest of the monitors yet - I want to play with something low voltage now LOL! Thanks for watching!
Great video - you show the process you go through while diagnosing it and the mistakes you make along the way. You keep saying that you don't know much about CRTs, but it looks like you're doing a good job diagnosing the faults anyway. So your knowledge may not be specific to CRTs but having a good general knowledge of electronics obviously goes a long way. 🙂 I like when people show their mistakes as hopefully it will enable us viewers to learn from them (those of us who also work with CRTs on an amateur capacity). I know I have made my fair share of mistakes but in the end they are inevitable and that is how you build experience, and I feel that I also learn something from watching this. So keep up the good work and I hope you keep working on those CRTs - they are an endagered species. 🙂
Thank for your kind words - well I am still alive so that's a good starting point! I am working on a small CRT right now, watch this space. Actually, it's going to be on the second channel, @Tony359_2 - aka "Tony259"
Be extremely careful with monitors high voltages but continue repairing monitors because it is different to usual computers. I support you and I am confident you will do all OK, go ahead!
Oh, I know that very well but thanks! I was always standing well far away when powering up and being extra-careful with High Voltage stuff. Thanks for supporting me and for watching!
Just picked one of these up, works perfectly! The only problem, as you said, is that the monitor doesn't get very bright. Blacks are crushed pretty bad on mine, going to try and open it up and fiddle with the contrast knobs in the back. Wish me luck!
Be extra careful :) One trick is to keep one of your hands in your back pocket at all times. And - disclaimer - you do that at your own risk :) The brightness control should be able to do the adjustment you need: display a black picture in a darkened room, now turn the brightness control to maximum: do you see the raster glowing? If so, the adjustment on the flyback transformer won't help you. If not, then set the brightness control to mid-position and adjust the screen adjustment. Again, please be extra careful and don't do that if you don't know what you're doing! :) Good luck!
The line output transistor (and power supply transistors on older designs) are often driven by transformers which make it look like a base emitter short when you check the transistor in circuit. Also watch out as some line output transistors can have internal resistors base to emitter, and also diodes emitter to collector. These can also make for confusing readings. And some very similar part numbers , for example a BU208 doesn't have the internal diode but a BU208D does
haha, love the Italian bleeping :D Great video as usual Tony :) I actually have two Apple IIc CRTs that needs attention too! Maybe it's time for some Apple IIc goodness
@@tony359 It had me laughing for a good minute at least lol. It felt very genuine. I guess it's part of the fun when we explore these things :) I think my IIc CRTs only need something as simple as a recap. Not sure how to make that into an interesting video
@@Epictronics1 ahah amazing! It came from the heart as I was not too comfortable working with high voltages and things were not going well so it was a mixture of anger and frustration!! :) At least the //c monitors have (or should have) schematics?
I'm just started to watch. So far is a great Video, and yes you're right Tony! LG is the fusion of two companies "Lucky" and "Goldstar" -> LG Let's see the rest :D
@@tony359 ah yeah Sorry, I went instantly to bed after I finished the video. It was great, the little fireworks was interesting, yeah you forgot to solder the jumper after you finished using it, it happened, lesson learned you payed the price, thankfully nothing too bad happened, and you'll be more careful next time. Once I did something similar, I bring a CRT monitor from a colder place to a warm room, forgot about the moisture. Big crackling, smoke, coil whine like sound. It was like this for 2-3 seconds. Thankfully I turned off in time. Fun fact the monitor Survived, without any problems. So anyway it was interesting to see a tube from technically the same brand, I wonder what the production date difference is in both of them. I need to cheat here: they fused in 1995 according to Wiki. Interesting the monitor manufactured in '96, and the tube doesn't get relabelled maybe some manufacturing rule. Oh well, keep up the good work sir, and try not to blow yourself up next time :)
@@bongey1 I'll do my best to remain in one piece! :) I'm not surprised about the Goldstar label. I guess it takes a while to re-name everything when you merge two companies. I guess they prioritised the brands which could be seen (monitor case), they probably did not care about a sticker on the CRT itself and exhausted the stock first. Interesting about that monitor of yours, good it's working! Thanks for watching! :)
Another good video by you. I also like someone who constantly says, I have no idea and nevertheless is working on a CRT. 😄 For the burned traces on the pcb, you must remove every black spot or you get immediately or sometime in the future so called carbon tracking, which in case can then destroy your board again. Even if this means you have to cut out a piece of the pcb. 😉
You know, I watched a video after making mine which mentioned that burnt PCB can be conductive. I guess I'll have to scrape it away indeed. I've got some solder mask coming, I guess I could cover up the hole with that. Thanks for watching and for your nice words!
@@tony359 Yes, you need to get rid of all the carbonised pcb. You can repair the hole with Epoxy Resin. I wonder if after you replaced the transistor the first time there was some conductivity across the burnt pcb affecting the 70 volts and when you replaced it the second time you cleaned out a bit more burnt pcb which removed the conductivity.
@@jameshearne891 Been wondering the same indeed. In fairness I was "lucky" to burn that transistor or I would have never discovered that there was an issue with the line. I'll fix that patch before powering up next time - if and when I get a replacement CRT! Thank you!
LG = Lucky Goldstar the FCC ID BEJ is for LG. I searched through my schematics and the closest I can find is the Studioworks LG56M Diodes and transformer numbers tally also the transistor Q953 which is a KTA1275
I've never had any luck trying to read axial resistors. I'm not color blind but the colors are hard to distinguish. Even when I can clearly make them out, the system still doesn't work. I can enter the colors into a web site that promises to decode it for you, and I will still get a completely different result when I check it with my meter. I tested myself on this with several resistors that should have been healthy and working fine. Maybe color codes were the only way they could mark things in 1873, but surely they could print numbers on them now.
Same here! I spend time decoding the codes, trying to figure the value out. Then I ask for some forum's help and it's always "oh no, that stripe is a custom one, ignore it" :D How am I supposed to know! :) Anyways, that's also part of the fun I guess! Thanks for watching!
@@tony359 bene! Io nel frattempo sto impazzendo con un monitor 9" comelit di videosorveglianza che ha l' immagine molto ristretta ho cambiato condesatori, qualche resistenza e rifatte le saldature ma ancora niente da fare domani provo cambiando un chip e un quarzo speriamo bene! 😮💨😵💫
yo! I’m having a strange issue with my 1998 iMac G3. It works without any problems initially, but when it’s left on for a long time, a weird bug occurs that’s difficult to pinpoint. After being on for an extended period, my iMac G3 simply goes into a black screen mode if there’s any change in video resolution. Additionally, when I turn it off and try to turn it back on, the power LED stays green, never turning off, and the machine doesn’t power back on. The same happens during a reboot; instead of the LED turning yellow and then green, it doesn’t return from the reboot. Even with the startup chime playing, the screen remains black. The only solution is to unplug it and plug it back in. After being unplugged for a while, it returns to normal, but the bug reappears if it’s left on for several hours, typically two or more. I’m not sure if this is an issue with the mainboard, power supply, or analog board. I’ve already recapped 100% of the capacitors, and while the bug used to be permanent, it’s now intermittent. At first, I thought the recap had solved the problem since I only used the iMac for a short time, but when I use it for longer periods, the bug always comes back. It only stabilizes if it’s unplugged for at least 10 hours. Any attempt to turn it back on after the bug appears is futile. Do you recommend checking any specific chip or shutdown signal? Thanks for the help. Oh, I forgot to mention, only the electrolytic capacitors were replaced during the recap.
Thank you! It’s a seek thermal compact but the pro version. It’s ok. The software could probably be better. Can be used with third party software on a PC. Its good good resolution but It’s not cheap though, there might be alternatives now from China.
Unfortunately it looks like a shadow mask damage. At 40:58 you can see that even a magnet is not moving those blotches, confirming it's not a magnetic field on the picture tube. Thanks for watching!
At least these don't have horribly brittle plastics. Apple at one point told all of their suppliers to use ABS-FR plastics which aged horribly. I just tore down a JVC-manufactured Apple Multiple Scan display for parts because I couldn't trust the thing to not fall apart on me.
@@tony359 They were looking for fire resistance above all else I believe. ABS-FR is usually a blend of ABS with PC or PVC. I believe they used the latter.
Goldstar os the Older Name for the now known brand LG. They renamed it in the 90s And that are a typical Monitor from the late 90s they are bad Constructed. I had some of these, and the most have the same fault, Even the discoloration on the CTR in the Corners. In my case that was a bad shadow mask. Like this Monitor. I Gave up to repair them. But i never had Fire in my Monitors.. :D Thank you fot that Video.
Very interesting about the discoloration in the corners, sounds like it might have been a manufacturing issue then. About the fire... well, it made things interesting (and scary!) Thanks for watching!
A user on Badcaps said it's something non-standard such as reliability or something else. The confusing thing is that you can also interpret that value assuming it's a 5-band resistor...
@Mr Guru Now that many viewers mentioned "Goldstar", I do remember the brand. As you say, it was a cheapo brand. A friend of mine explained me that major manufacturers have people and software trying to predict the failure of the product. They design them to just go over warranty time, then it's not their problem. You really don't want something to last 20 years, do you? :) It hurts when you see some boards with components running at 80C as you say - they won't last forever for sure and a small heatsink is all they need - Check out the ARCAM repair video I have on my channel if you're interested! ruclips.net/video/SrR5L15Rau0/видео.html
Those blotches look like there are dents in the shadow mask. Given that it's a thin metal sheet with holes in it, it's very easy to damage or deform it.

Thank you! Yes, disappointing a bit but I hope I can find ONE working tube from the pile of those monitors :) Thanks for watching!
Great fix! And yes, sad that the tube is junk. 100% that is a damaged shadow mask.

Also, the power macintosh 5XXX machines should have the same CRT so if you have one of those machines all crumbled and falling apart, Swap the tube.
I don't have any unfortunately but thanks!
I believe the color impurity issue on the tube is a result of the degauss coil not doing its job.
