My Sharp LC-46LE700UN will not power up. Power led flashes twice and OPC LED flashes once. I downloaded the Service Manual. The fault description is: DET_15V (34pin) error (L). UR13V is not applied. I assumed the Power Supply Board was bad so I changed it. This did not solve the problem. What else could it be?
