Hi,
Got this used AOC monitor from a cybernet cafe complain of it displaying just white screen.
I checked the power board Changhong 715G2510 -1-4 Ver:B and detected 5vdc (both red wires) at output pin CN902. In addition, i also detected 5vdc (both red wires) at the input pin CN201 of the smaller card.(controller card?)
Next i checked the t con board but found only about 0.02vdc at the 5V test point. There is no other voltage detected on the t con board.
The only fault suspect is the controller card. My suspect could be wrong and hope someone experience can point me in the right way.
Can someone kindly assist and guide me in solving this mystery of the missing voltage. I am looking forward to learn and diagnose from the basic step if time permits.
