Hi all,

I have this Acer AL1717 F working lcd monitor, but yesterday the blue led light on the front switch does not turn on and thus no display on screen. Upon opening the outer casing, and looking at overall board (image 112637), i do not see any burned parts or bulge caps. Fuse T2A measured with continuity.
The main caps has around 340vdc. Tha main board(image 113242) has vcc 5vdc on pin 1&2 on the red wire. I would like to understand what is going bad and to request for any guide and kind help to replace or repair the bad faulty part instead of throwing this monitor to dump. Any generous assistance in the right direction is highly appreciated.
