Question about Panasonic SC-HT740 System
I checked speaker cable connections like manual said but did not work
Hi, when you say it doesn't work, will it just not play/read the disc? Mine has to be "initialized" every time or it shows "No Disc". To initialize I turn the unit on then press and hold "Stop" on the unit and the "10-" button on the remote, then it works fine.

I have a very similar problem with the same exact Panasonic sub. I went to Best Buy and Radio Shack looking for an adapter, and they basically told me that one does not exisit. Apparently, Panasonic designed the home theater system specifcally so that it could not work if any part of the entire system was ever seperated.

Generally speaking, an amp protects itself from heat, shorts and overloads.
Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
