Customer Question

The symptoms of my Sharp Aqous LCD TV is at first there is a back light and sound but no picture, so I decided to order a new T - con board. The replacement is identical with # ***** RUNTK 4242TP ZA and install it. When I plug in the TV the result is no
screen or black screen ,no back light,no sound and the power and OPC led is flashing. I downloaded a Sharp firmware then install it, still the OPC and power led is flashing. What went wrong?

Hello, how many times power and OPC light blink?

Do they blink in specific pattern like power blinks 2 times then OPC blinks 5 times?

Also, where did you buy the replacement t-con board and can you put old t-con board to get previous symptoms in TV?

These info will help to troubleshoot the problem.
