Sanyo DP42740 keeps blowing fuses

[JunkmanJimbo]

Sanyo DP42740 keeps blowing the two fuses at the main power cord connection. I have replaced both and they continue to blow when I plug in the power cord. With everything disconnected from the power supply board, I connected each cable one at a time to try to determine when they blow. When I connected the analog board the fuses blew. Don't know if this has anything do with it or not. Any ideas? Thanks in advance.

With just power board connected does it blow fuse?

No, it does not blow the fuses when just the power cord is connected.

If you look at this TV as a Panasonic Hybrid it makes sense. The Analog board would be sending the command to latch the 2 relays which applies mains, sounds like the power board FETs will be shorted out and who knows what else. That's where I'd start. shopjimmy does a kit for common failures.

Amaybe that's also a clue where to look.
