Monitor Samsung T200 (T220 & T240) blinking light and doesn't start

- My Samsung T200 Syncmaster (works as well for T220, T240 etc) broke. It only had the main light in the corner blinking. I googled and got basically "Power supply is kaputt ..." as an answer.
So here is how to open an Samsung Syncmaster T200 and how to replace the broken condensators.
Costs you around 1-2 bucks (euros or dollars) and an hour of your time.
I just did everything as you instructed. You saved me a monitor! Thank you!
Thaths why I did it, you are welcome
Once upon a time I could have done that too. Bravo. Good to see that there are still electrical engineers around.
And stuff like this is thrown away. It works perfectly fine. But getting it to a shop to repair is more expensive than getting a new one.
I just repaired my monitor using your guide. Thank you for sharing this information.
Thank you Dear Sir! I put two new Capacitors in and my old Monitor is working again. In the beginning it had a slight flicker, but after a few minutes it stopped.
THANK YOU!
Excellent video, well done. I am English and I can understand you perfectly.
I only got my current job because of my english skills. And thank you, I appreciate it very much! :)
I'm facing exactly the same problem, exactly the same capacitors :D but I will replace all of them. Actually very good video, it has shown how to disassemble this sucker
Thanks Mr Delicious! Your vid gave me courage and tips how to open the case. T220. Removed both circuit boards - nothing obviously wrong to see. Put it back together. Still Kaput - no sign of life, as before. Time to retire this beautiful old lady . . .
Yeah, mine broke again as well but after 14 months of continued service. It's a great machine :D
@@Commandelicious Some people have said that there's a chance that rather than popped capacitors, it might be the backlight that's problematic as the wire connectors can get burnt off the backlight. Might be worth investigating! Thank you for the video!
Thank you, friend! Just fixed my monitor that previously was lying half dead for several years. You've made an incredibly helpful guide!
Happy to help!
2:28 - _"They do that because it's easy to assemble, it's annoying to repair this thing from the case..."_
And that when I knew, this was gonna be a fun project...
Replaced two bulging 16V 1000uF caps (c113, c116 I think) with some large 50V 1200uF caps I had lying around from another electronics project... Wasn't easy to squeeze those larger caps inside of it, but it's working again. The new caps I put in are also rated up to 125°C, instead of 105°C for those older caps. Hope it extends their life a bit longer.
People that are in a cold room can potentially identify the issue without even opening up the display. Blow a hot hairdryer on the back of the monitor for 5 to 15 minutes, if it turns on the caps are most likely the issue. The caps optimal working temperature are typically around 25°C, colder or higher temperatures are an disadvantage and could worsen the problem. I heated the monitor almost every morning for the past 3 to 4 months, before replacing those caps :-/ . However, this trick doesn't work every time, so keep that in mind.
Thanks for guiding me trough the madness of today's plastic case frustration. I'm 30 and am jealous of my dad's old equipment that's put together using bolds and screws, instead of clips and glue.
thank you. i just fix the t220. i replaced two capacitors. i always keeping a old broken psu and motherboard for donor and i found the same capacitors. i have a issue with the side panel that goes crazy and i have disconnected it.
i have this monitor from when first released and still have good specs even for today
You just saved my monitor! Thank you very much!
The reason I made this for, my friend!
had the same issue and fixed it with this vid, thank you so much!!!!
Happy to help!
To get the stand off easily, screw the base back on, then pull on it on the left and right sides repeatedly, it will come out a bit at a time, each time.
Thanks, I have an old one with the same problem and now it is fixed and ready for a third life...
Mine SyncMaster T220 is blinking for an hour or two without any on-screen graphics and then suddenly turns on and works OK. I reseted, pushed and hold all the buttons, etc.. Is it the condensators and would it help if I leave monitor on permanently (and just keep turning computer on and off)?
Why haven't you changed all the electrolytic capacitors ?
Any chance you cna help me bud I have stripped mine down and all capacitors seem fine no bulges on them at all, can't see any other faults on the board either
HI thx for a vid. I have a one question are this capacitors should be LOW ESR models or normal ?
Thanks I'm repaired my Samsung, good job!
Hi, i'm currently following your video since i have T220 (normal, not HD version) that was flickering a lot, and then one of the capacitors (or more than one) died and cannot hold the backlight on. I'll post the procedure here since i can't record it.
To remove the stand, you don't need to press it, just put your monitor on a flat soft surface (for example bed), then turn it upside down (be careful, first put your monitor on the bed in a normal position since the stand might slide out because nothing is holding it) , then unscrew the stand, remove it, and after that the vertical part should slide out (mine didn't but you can hold the frame and pull the vertical part out while holding the frame, it went out easily that way).
Conclusion: 1 bad capacitor. Electrolytic capacitors inside T220 are more or less really cheap.
To replace all of them you'll need:
4x 820uF 25V 105*C
2x 1000uF 16V 105*C
1x 330uF 10V 105*C
1x 100uF 16V 105*C
1x 47uF 50V 105*C
1x 3,3uF 50V 105*C
uF - micro Farad.
It shouldn't cost more than 5 euros, at least in Serbia it costs around 3.5 euros + shipping/delivery (postal expenses).
Almost forgot, the big capacitator is 450V/100uF as i've seen from the internet since it doesn't say on mine, it costs around 8 euros but i doubt that one is/was the issue anyway.
I was pulling like a mad man, that's why I thought there were screms at the start :D
Me too and i was wondering if it got stuck since i doubt it was ever removed during all those years :P Also managed not to break anything so far so i guess it's a success, now i need to wait for the parts since it's weekend :)
I had to buy another one since that is my secondary screen that i need for work, bought a Full HD Benq for like 20 euros, it has thin green line that dissapears, probable flex cable issue, i'll fix that after i fix this T220 :D

It woked fine for me. Thank you very much!
Happy to help!
Dicas valiosas! Muito bom!
Can you tell me what is the degree of his polarized film?
I wanted to change the one on mine, but I don't know the degree of the film...
Nice vid! You didn't record the blinking issue? (am wondering if I have the same issue...)
I didn't. Its a slow pulsing of the red LED
Some time have passed - is it still working? Did you have to replace other caps as well, by any chance?
It usually works for all errors that include a switching power supply. And yes, other capaciators could be broken as well. It's easy to identify those if you seen it once.
@@Commandelicious Sure, thank you.
Do you have their values as well? T220 is on the way to me, and I'd love to be able to order them in advance.
@@cthulpiss Oh sorry, I missed this reply.
My Monitor finally gave up again and I haven't checked on it because I am just using a bigger one and don't have the time. The values should be on them and no I don't have them in my head (and I guess it's too late now anyway)
Hey, I have t220 it started blinking at low brightness, then top half of the screen became dimmer and after a while whole sceen went black completely. Do you think changing caps could save it?
Maybe?
To check for broken capaciators is really the easiest if you know how to. If it's not that there will be trouble shooting and thats a whole other story. My tip always is: Doesn't hurt to look :)
is my brother missing from the parts exchange demonstration?
Hi !! My screen blink like you said and I hear a little noise in the back but after 5 mins the screen turn on by itself and the noise gone after blinking randomly for 5 minutes but after the screen turn into black and white and the settings is messed up and sometimes the brightness become too high the white color so shiny and still blinking tho when I turn off and back on again you think what you did on this video will solve it ?
I have an other problem with this monitor.It turns on the menu and cant stop it.then the pic goes thub.
I just opened my T220 - all of the condensators look just fine, none of them are bulging, all are flat. What else could be the issue? I have that issue where I have no image at all and my power button is blinking rapidly.
Then I am not sure. :/
It.s still somewhere in the power supply 99% chance but you have to look >
@@Commandelicious any tips or links on what should I look for? I am a complete newbie to all of this.
Well, my problem is this. I have dual monitor set up, but I use T220 occasionally (it is not on all the time). So, when I turn on the T220, I just see power light blinking and some sound like whistling (stop and start) and maybe after 5 - 10 minutes, the whistling is gone, the power button is solid red (no more blinking) and there is picture. It happens every time. Do you think it is related to condensators? So, essentially I need to replace 4 condensators (2 of one kind and 2 of another kind that you mentioned)?
Yes it is. Like, most probably it is. It happens to many many power supplies in all kinds of electronics.
So it can be that it works when it's a bit heated up :)
All right, it worked. I only replaced 2 capacitors that were bubbling up. The other were ok. I didn't want to touch them and maybe create another problem. We'll see how long it lasts. Thanks.
standard problem power supply 470 micro 25 v , or 680 25 v , or bad organization heat out , this monitors or tv this series only this problem ,
Hallo,
ich habe auch die schnell blinkende LED beim 2493hm. Aber kann kein Elko finden der gewölbt ist.
Hab auch nen Knall gegeben bevor der Bildschirm ausging.
Eine Idee was es sein könnte?
Danke
Lg
Tatsächlich nicht, aber knallen sollte der nicht wenn das Netzteil aufgibt.
Wenn du da nicht sehen kannst wo er geplatzt ist rate ich dazu einen Fachmann aufzusuchen.
Knallen tun aber eigentlich nur Transistoren. Da kannst du mal schauen ob bei den größere etwas abgeplatzt ist.
@@Commandelicious Danke - dann werd ich die mal anschauen
How to check this inverter 6 + 3 pins
Hi, i have samsung T200 monitor with some other trouble, monitor powers on but dimming white screen is presented and after maybe 10 power on power offs monitor starts and works. Do you maybe have an idea what is worong wit it?
Thanx
That could be the capaciators as well.
I am not entirely sure what you mean by dimming white screen.
In my experience the only thing that actually breaks in modern flatscreen tech is the power source.
So it could be the switching power supply as well.
@@Commandelicious Thank you for answer,
The simptoms are exectly as this :

The white color is starting to apear untill all screen turns white.( just without the white line as in this video)
I can't open that black LCD panel which has Samsung written on its back. Plz help me
Have you pulled really hard on the stand? There is no screw there, you have to pull. other than that, it's in the video. ^^
@@Commandelicious no not that I pulled the stand I removed that "thing" which requires a lot of pulling...
.
Then there is that thing which I have to pry...
😫😫😫 which I cant
