Hi,

If cases like this occur, then the mechanism of the home theater is damage.

The mechanism is an IC which control the home theater is connected to the panel with a cord.

If the mechanism is replace with another one of the same model number, the home theater will work fine.

Thanks for contacting Fixya

Chances are the unit's trying to power up, but experiencing a current protection overload and shutting itself down before further damage is incurred. You might try the remote control to turn it on, as someone had luck doing that with a simliar problem. You can disconnect speakers and components, one at a time, to ensure nothing outside of the main unit is the problem. Once you isolate the unit as the problem, it will have to be troubleshot and serviced. Usually part of the power supply or amplifier circuit is faulty in these types of units, but that requires troubleshooting the circuit to isolate the bad component. Take it to a reputable shop, and get an estimate so you know what to expect for a charge.

My subwoofer shuts off when I turn it up too loud. How do I fix it?


Don't turn it up so loud.
Or get a bigger subwoofer.

It's got a junk 6.5 inch speaker and the amp barely does 50 clean watts.
Claims 167 Watts at 10% distortion - impossible when it is drawing 160.
TOTAL BS.
Drive it too hard and protection circuit will cut in and shut it down.

How do I get the sound from tv to play through when just watching tv?


If you don't have audio RCA output jacks on your TV then you will either have to open up your TV and add a "ground isolator" type device to the speakers and create an RCA output or else you could use a VCR tuned to the same channel as your TV and use it's RCA audio outputs to go to your stereo. If you don't know what you are doing, I wouldn't recomend you open up your TV and start changing anything though. Good Luck.
