Customer Question

I have a Sharp LC-46SB57U liquid Crystal Tv. It al of a sudden will not power up black screen and power light blinks 2 times and then a third time along with OPC light. It was suggested to me that it could be the power supply board, ordered and replaced still same senerio. Does the lights flashing indicate anything some online blogs say there also may be a reset or software update may need to be done.

Hi , I`m Jack
Perhaps I can help you with this problem but first I need to make sure about that blink code

Are you saying the power flash twice and then a 3rd time along with the OPC ?

In other words power 3 blinks and opc 1 ?
