Question about Panasonic Home Theater System System
The digital in port on the back of the receiver does not work. There is no light coming out of the port. The cord and digital out on the TV work (hooked up to other receiver, no problems). The HDMI and iPod play, so the speakers are fine. There is not a coaxial connection, so I don't have any other way to hook up the surround to the TV.
Select to suit the type of audio from the OPTICAL IN terminal on the main unit.

I just bought a sc-pt660, I have a philips tv too, the TV only available output is digital coax but the home theater only has digital optical input, you may buy a digital coax to optical converter like this one:
Alternativelly you can also use the headphone output that is near the side input in the TV and buy an RCA adapter like this one from radioshack: http://www.radioshack.com/product/index.jsp?productId=2103225

SOURCE: blu ray connect to my sc-pt660
Why not leave the audio into the TV via HDMI from the Bluray and then optical audio out from TV to the home theater audio system? Same as the hook up for the cable box. The SC-
PT660 only has one optical audio connector so your solution may not be feasible assuming he's also got a cable box connected to the TV.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; 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. Eure 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 and competent hands-on tech.
