I have a strange problem with my tv.

It keep on blowing H-out transistor (IC522? - 2SD1876) after power up.
I have tried to change T522 (Flyback) and still have same problem.

I have resoldered all "cold" points as I can see, and can't get my tv to work again. Where can I continue searching?


Thanks for quick reply.
