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

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.
