I turned it on, had picture, changed channels still had picture then it went black. sound is just find. using the remote volumn by ear and channels by memory. the programming or channels do not show up on screen. The has not been any warning issues either. I live in Florida and recently we have had severe thunder/lighting storms, but nothing with a direct hit. That was a day or so ago. Any Idea if I can reset it or not? help, please
Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

I had the same problem and Sanyo does not make parts for this model anymore. Luckily I had the extended warrantee so they reimbursed the full purchase price.
Weird that the poster above mine was able to get a part; I was told the part is no longer available.

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

If your Tv is in warranty or you have a cover plan, you need to return the Tv for repair or replacement.Your Tv sounds like it has a power supply fault.
