Having problems with your Samsung 931C LCD Monitor ?

I have a samsung 19 inch syncmaster 931 c monitor.backlight issue

\015 I have a samsung 19 inch syncmaster 931 c monitor. It was failing on me an would flicker the video on and of when you turned it on and you would have to turn it on and off several times up to a half hour to get it to stay on. Finally it just stopped and would only flicker the backlight on and off continuously. I took it apart and found that 3 of the capacitors were bulged so ireplace them. they were 25 v but I replaced with 35v as I was told you could go higher just not lower. I reasembled it and powered it up and now it just turns on and the screen stays lit but no image and does not even ask for a video input it is basically a lamp now. any ideas where i might need to go next. thanks Rob\015

Answers :

1. Check that you did not accidently bridge any printed circuit tracks when you replaced the caps.
\015\0122. Make sure you put the caps in the correct way round. (they can only go one way).
\015\0123.It may be that another fault cuased the caps to go - if so you will need to find this fault - it may be difficult if you have no test equipment.
\015\0124. The 35v caps are OK as long as the values are the same.
