(the board number is A1302708A) After replacing the IC I am still experiencing the same problem as the standby light is still blinking four times. I am asking if you can assist me with the problem and a service manual will be greatly appreciated. thanks in advance." I have a KDP-51ws655 and the standby light blinks 4 times I just replaced the g board with a new one cause it wouldnt power up at all, and now when I hit the power button it acts like its going to turn on for a sec then shuts off the light blinks 4 times, Also when I push power the sound of the of it trying to fire up or the ping of the power supply is pretty loud I dont know what that means, Please If anyone has any idea on what I need to do please tell me I would like to fix it myself......
