My home theater system has begun to turn the audio off after awhile. Sometimes a few minutes and sometimes an hour. The video continues fine. Does this on every DVD. You can hear a click when the audio dies. I suspect a component temperature failure. Any help on which component is the culpret would be greatly appreciated.
Had the same problem and eventually the sub won't power up at all. 120VAC Input voltage to unit is present but when power transformer is connected it drags it down to about a volt or so. No opens or shorts on the primary of the tranformer but I suspect it's faulty. They run about $80-$90 new but I have more checking to confirm it's pooched.

Re: Audio switches off after time.
HI.... I was wondering where you keep the unit... Is it vented OK? Is there dust about? And , like the jan 25th comment, it could be just a bad solder joint or loose electrical connection. It's not the transformer cause the video keeps working. I would check all the speaker wires to make SURE theyre all connected solid at BOTH ends. I have a Harman Kardon AVR in the shop and the customer said it shuts right down after you tunr it on,,,,,,well it'll do that if the speakers arent ALL connected.

When viewing on Digital TV:- Sometimes Audio and Video signal can not be transmitted simultaneously due to additional process time for the video signal compared to that of the audio signal. Often video signal takes more time than the audio signal to convert from analogue signal to digital signal in the Digital TV. It may result in mismatch of the picture and sound. In the TH-G30/40's HD AV Sync menu, you can adjust the audio signal delay for simultaneous AV signal transmission
1. Delay time can be varied in 10msec steps.(0 to 300ms) 2. Delay time is different between TV Brands.
So you need to adjust the delay time for correct lip-sync. The adjustment is listed in the instruction book page12
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.
I have a Samsung 55 inch plasma that has experienced intermitent garbled audio, sometimes very frequent (a couple of minutes between episodes) and long in duration (several minutes). Switching to another channel and back would correct the audio.
I ran the auto program channel function a couple of times and it eliminated the gabled audio problem, except for infrequent (once every hour or two) and very short (a second or two in duration) episodes of gabled audio.
I found a thread on a CNET forum on this subject and it seems that the garbled audio problem affects a number of Samsung flat panel models.
Protect mode will kick in whenever a fault is detected.
You get the unit not powering up, and sometimes you hear a clicking
noise, that is the protection switch that keeps shutting down the unit.
Causes that can start protect mode are:
Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.
Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.
fault is the natural cause for protect mode. If all the above did not
work, then the problem is a blown component or an internal fault. In
this case the unit must be taken apart , tested and repaired by an
If the unit is less than one year old, or if you
want to get service, call Sony at the phone number listed on the
