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.

You can run the sound to the home theater system in many cases. It depends on the home theater system and the TV. If the home theater system has a digital audio input, it is easy to connect most 4K TVs. Connect the 4K source to the HDMI or Displayport connector on the TV. Check whether the digital audio uses an optical cable or a coaxial cable. Make sure that the TV has the matching output and get the correct cable. Set the TV to use external speakers (under the Audio part of the setup on most TVs) and turn off the internal speakers.
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
Check your different settings either in your t.v. or your amp. In your menu settings you can change your audio. Bass trebile etc. and even sometimes switching it from stereo,mono, dolby digital will increase your volume. Dolby digital is very quiet if your not running and exteranal amp system. so try changing it to stereo and your volume should increase.
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
