Hey guys!
I have LCD monitor which was working just 5 minutes after you plug it in.After 5 min it turns off.I have opened my LCD and i found one bad cap.I have replaced it with brand new(its 400v 100uF).After that I put all things together and now my screen is white.Sometimes it happens to show picture for 1-2sec after I turn it on.I turned my LCD once and it was showing picture for about more than 7 minutes.I turned it off to put all things back and after it is showin white screen again!! please help

Fractionally better but still not in the right section!
Check again the lvds cable that goes from ?????? board to the panel.
I cant say which board as you have posted no pictures and not even told us
the make or model of the monitor.
Pictures please - one of the back showing the general layout and one of each board.

well,I know about what cable are you talking about.I have spent almost 2 hours of trying cable positions.Its not about cable...Well there is connection on the power board which says +5v output.I took my voltmeter and I saw that voltage is chaninging from 4.9 to 5.13 very fast.It has to be constant or?
