Sounds like the green tube shorting intermittantly. Have a qualified tech use a tube restorer to check for shorts, or the loss of the 300v line to the green tube.

If the sound is distorted, then you need to replace Sound board. If you do not have picture and sound, it has nothing to do with sound board.
There might be millions of reason and depends on the make and model of the TV.
On most of the samsung TV's, such problem might be due to defective Circuit Board. It can be replaced or repaired.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

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.
