Hello,
Tv was working normally then went out with a pop. Now I have no sound or picture. Power light is working normaly. I replaced the convergence amps about 4 years ago. I've downloaded a service manual but have little experence fixing TV's but I'm guessing a power supply issue.

Thanks for any help,
Rick

Power supply or horizontal output or even convergence again. Cool

Check the pico fuses in the power supply to see which one blew.

Of the 11 fuses 6 were ok 3 were bad and 2 I can't get to without removing the board. What caused the fuses to blow?

Here's a clue, 2 of the fuses feed the convergence IC's.... Replace the 3 5 amp pico fuses and convergence ic's.

Man, I dunno... 3 fuses blown?? Did somebody drop a screwdriver in there?
Even with shorted convergence IC's , I've only seen one of the 24V lines blow a fuse. Most of the time the fuses are OK .
There must be more to this story...stay tuned!

Maybe there was some chaff mixed in with those party favors. Very Happy
