Re: Hanns-G HG281D, LCD Monitor no power
I got my screen working now. After replacing the three small caps on the power supply as others did (C603,606 and 707) and replacing that mosfet I burnt. But I think that I need to recap the control board (logic board) and for sure the power supply. The image on the screen when I turn on the computer is shimmering. then it heats up and it look good.
I think that it's because some of the caps might be a little out of spec. so when they are cold they have hi ESR.
Any comments on this thinkingLast edited by Mark369; 03-03-2014, 09:39 PM.Leave a comment:
