Check to be sure that there is no voltage on the input line. You don't indicate what input you are using. Since the set appears to work without an input connected, try looking at the input cable. Also, if the problem is internal to the set, shorting the input jack would cause the same behavior. Please update this with what you find.

Black Screen come from three areas. 1- Power Supply Board 2- Inverter Board 3- Processing Board on the LCD. Since the Power Supply Board was replace, it easy to troubleshoot where the problem. lies If you cannot get the backlight, then its the inverter board. If you can use a flash light on the TV screen and can barely see the images, then the problem is indeed the inverter board. If you cannot see any images when using a flash light, then the problem comes from the LCD processing board. Let me know if you have any success. Mike
