Failing power supply

Well, this is the kicker, Fuses don't go bad, a fuse is a piece of thin wire that either allows current through or it blows and stops the current. Fuses DO NOT give intermittent faults.

It was $2,500 new!

However, it is a good deal, even if you need a new sound board, or possibly a new switch. Visio are a cheap brand, and it is plasma.

Offer him a $100, settle at $125, not sure if I would go to the full $150 on a Visio Plasma.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Be sure that your signal is strong enough coming through the HDMI or coax. If your signal is strong enough, it may actually be your TV's power supply needing to warm up.

Fuse is located on the power supply board inside the TV.

Your input cable is in wrong slot...switch around and it should work.

sounds like you have a bad capacitor(s). my TV did the same thing, so I removed the back of the TV and looked at them and noticed (9) of them were bulged at the top ( should look flat). I am no electrician by any means but was able to replace them with a slightly higher voltage myself for around $45 instead of someone servicing it for $400
