Without the make and model I can not give you details. However, the TV is detecting a problem and shutting down to prevent further damage. The most common failure is of hte horizontal output transistor. This is a 3-legged part attached to a heat sink close to the flyback transformer (part with large red wire coming out the top). Try replacing the transistor first.

Won't turn on


those tvs will try 3 times before completely shutting down. you can try and take the back off and check CP150 it is a large capactior located near the middle of the board on the left hand side(looking from back) if it looks and feels like the top is vented or puffed out then that could be the problem. if not i suggest having a qualified service tech take a look because there are too many things that could be the root cause.
