Tru using your remote to access the factory reset mode to default. It might be hard to find, but it should be listed in your tools or settings options somewhere. Also, you can unplug the set for 5 minutes and then plug it in again. This resets the computer in several models. It's like a hard reboot.

I have the exact same problem. It's a volume control issue. For me, when I turn my TV on and have it on low volume, it works fine (but sounds somewhat distorted). But once I turn the volume up to normal levels, the speakers crackle and then go out. I opened my tv and checked my speakers, and they were perfectly fine; not blown or anything. As well, the audio processor and circuitry didn't appear burned at all.
This used happened every few months for 30min or and hour at a time. Then, about 2 months ago, it happened again, and ever since then it still hasn't worked properly. The only way I got around this was by buying a cheap 2.1 speaker system, and connecting it to the audio output on the TV. Or you could buy a speaker bar or home theater system. I believe this issue has to do with problems with the circuitry in the audio amplifier, and there's not much you can do except add external speakers, or contact Sanyo if you still have an active warranty.
Depending on where you bought your TV (such as from walmart), its possible that the LCD panel was produced by Sanyo, but the electronics were done in China. Walmart does this with nearly every TV they sell.

Hello; I am John at J. D. Electronics, Poland Maine. This problem is caused by a defective LCD panel. This part is very expensive! Aprox $ 1000.00 from Sanyo and less than $400.00 from Encompass Parts Inc.
