Hi, TV is 3.5 years old. Worked OK till yesterday. Completely dead. I opened it and identified fault to be on power supply board. Nothing comes from it at all, apart from some like 15v dc at one terminal instead of 33V, nothing at all comes to little board with switch batton and infrared sensor. tested main components on PS board (semiconds, diodes), nothing found. As well fises, and on line cracks and cold solder - all fine both sides. So angry it's happend 4 month after 3 years guarantie expired. Pazzle, can't solve it by myself. Please help! Kind regards Andrew
