Toshiba h65hx81 projection tv

[bay44]

I have a projection TV Toshiba 65hx81 which no longer produces a picture when powered. The power indicator flashes. Toshiba online support said a flashing power light indicates internal failure? I've tried plugging the tv into other sockets with no luck. What do you think the most likely problem is and how much should it cost to fix? I've called a few repair places and they charge 100 for a service call and said typical charges are 300 to 500 for repair. Is this about right? Any suggestions? Thanks in advance.

Convergence IC's. $350 is the average. $40 if you do it your self.

this model has a problem with jumper under plastic molding covering hyper board.when this goes bad it blows 1,2 or 3 pico fuses in secondary of power supply.this jumper is right under plastic to the right of flyback, but on the other board.
