Samsung 226BW flickers for a few minutes when powering on - Page 3

post #21 of 114
Can I add my thanks to Dricks for his wonderful guide. I ordered the same caps off eBay that Dricks did and although 2 of them were much bigger than the originals - I kind of worked them in... I only hope the cap I placed on it's side is gonna be OK (although it's not actually touching anything else) ...but as I write this post, I'm looking at a beautifully "fixed" Samsung 226BW that flickers NO MORE!!

Thanks again Dricks, my soldering skills are OK but I had to be a bit inventive with fitting the second bigger cap in as I had to make certain it's legs and top weren't touching "anything"... you can see the original cap outline underneath.. but hey it works fine!

Order capacitors from here: http://www.mouser.com/

I had the same problem a year back, initially the screen would flicker, as it got worse, it would keep blinking every time I turned it on until it stopped blinking after awhile and then one day it would just keep blinking non-stop.

The capacitor on the PSU blew, ordered some quality capacitors from Mouser and wha-la! Works like new.

Glad to see you've been able to repair your monitor wink.gif
Regarding the size of those capacitors, i managed to set them more closer than you did, having both with the same pin length, then the top one going top-left, and the bottom one going right-bottom.
Those capacitors are a lot bigger, but the LCD panel himself will die before they do, for sure wink.gif

I made this repair some days before this post, 8 month ago, and my 226bw is still working great since then.
Worth the time and the 5$ investment thumb.gif

Man I'm glad this thread popped up. My 226bw has been flickering at startup for a couple weeks now, and I figured it was on its way out. Thank you for the awesome guide dricks. thumb.gif

Hi Cibelle,

I have the exact same problem as you on my Syncmaster 226BW: Started acting weird a month ago (will not turn on, stays in standby mode)
Then it stopped working completely. No power, no blue led.

I have replaced the power supply completely, thinking that this would solve my problem, and still nothing.

I am worried that I have spent 40$ on a useless power supply frown.gif

Have you found a solution to your problem? Anybody out there that can help me?

Thank you,

It is possible that the new power board that you have has the same problem as the old one. I suggest reviewing the sticky in the Monitors and Displays section on monitor repair. I use this monitor in the tutorial and it is more in depth than the one posted in this thread.

If you can post pictures of the old/new board and we can help you troubleshoot.

I'm so glad I found this thread. My monitor has been doing this for the past month, I don't have the money to go out and buy a new one, so when I give this a shot hopefully it'll work.
Thanks dricks thumb.gif

I have the same problem since September this year. My PCB seems to be a different version then the one the topic starter has. Anyway, I replaced them with the same value's but the flickering is still there.... Does anyone have a clue what it could be? Maybe the other capacitors should be replaced also?

Please refer to my sticky in the Monitors and Displays section. There is more to capacitors than just the values on the side and if they are leaking or not.

edit: I'm guessing that either the caps you've replaced are incorrect or there are more on the board out of spec. There could be other issues, but they require tools that are more expensive than just replacing more of the capacitors

I followed your instructions and replaced all of those crappy capXon capasitors, and the monitor is working like brand new! Thank you very much! €10 on electronics and I saved myself €190 on a decent monitor!! thumb.gif
