Hello,
I have a Benq 19" that does not start neither the Led lights.
I checked the Power Board, and not seen swollen capacitors. Apparently voltages are OK. I have 5V (4.9 V) and 3.3 V (3.28 V) to enter the video card.
I measured the PW_SW signal entering the pin 2 of IC Flash MTV312MV64 which is 3.3 V and when I press the power switch it goes to 0v. I also measured the reset signal that is 0v, it's correct? The LCD shows no sign of life and not try to start....
I do not have much experience in repairing LCD however it seems to me that this IC MTV312MV64 works as bios/rom lcd ...
can someone give a hint where to start measuring and what should I measure?
I have the service manual with schematics for those who need it. How can I upload?
Thanks
