Philips TV 14GX8510--tda3653b keeps blowing and led blinking

[[email protected]]

When i plug for the first time it was dead tv and led blinking. So, i
replaced vert ic TDA3653B (ic7400). Then i turn on and it was ok.After
threee days TDA3653b blows again. Then i replaced again. Now it lasted
just one day. What's going on? I checked diodes and caps around vert
ic and they were ok.
Any ideas? Thanks.

Replace the diode and caps associated with the vertical circuit
and make sure the TDA has clean heat compound on it.

Have you checked the esr in the electrolityc capacitors near the TDA or
measured the capacity.

An electrolityc can have enough capacity, but an bad esr (internal
resistance) can damage the circuit.
