Question about BenQ FP767 17" LCD Monitor
I am having this problem with one of my BenQ FP676. The Power LED blinks / no image (backlight off) although I can see something being displayed when using a flashlight (image also blinks in the same frequency of the power LED).
The fuse is OK, of course (I have checked)
I have tried to find the schematics online but was unsuccessful. I wanna test the transistors, but (to be sincere) I am lost on this board. Do you have any hints to find the schematics online?
I'd really appreciate your help.
Look for small power transistors 2SC5707 near yellow invertor transformers which go to backlight connectors.
But if problem is blinking power LED powersupply capacitors maybe an issue,check visualy and/or replacement.
Also fuse that maybe blown is not glass fuse near mains socket,It is semiconductor black or yellow colour labeled PFxxx near heatsinks of power supply secondary.
Please rate the solution and provide feedback.
