Question about Sony KV-36XBR400 36" TV
My TV is about 10 years old. When you first turn the TV on it stays on for about 15 minutes, then it turns off. Then you turn it on again it stays on for less than aminute before turning itself off again. Is the power supply going bad? What else could be causing this?
Problem is in the secondary power supply which provides power to high-voltage and scanning sections of main board. This is called BOARD D, and has the high-voltage section, flyback transformer, and control IC on it.
Can't be fixed by user, needs service tech and new part, around $300
