Title: Samsung SyncMaster T240 LCD screen problem
Post by: stdcall on October 16, 2015, 11:40:09 am

Hey guys,
I'm been troubleshooting quiet a while with my LCD screen.
First, there were these 2-3 seconds blackouts where the screen got black.
I replaced all the bad caps, and the issue was stable for about a year.
Then, it happened again, but the caps were OK.
So I replaced the backlight inverter.
The issue was solved, no blackouts. but now, I have these weird green and pink pixel spreaded on the screen. (I attached an image)
I'm quiet positive that it's related to the power supply board.
What could be the issue now ?
