Sound fades/ intermittent sound

Sounds like possibly it could be connection related between any AV/Cable ports. Worst case would be the capacitors of the motherboard leaking. It's possible to fix anything. Just make sure you have the knowledge and the right equipment.

Returned to repair depot for over the counter exchange. Paid 300.00+ for the service.

This chassis model line had issues with the vertical output IC shorting causing shut down.
It also had issues with intermittent solder connections in the Horizontal Circuit. I would not try to fix it your self unless you are very familiar with Projection circuitry and electronics background.
Hope this helps,

I have a brand new Panasonic 42" tv, once in a while the sound fades out and then fades back in right away. I have it hooked up to a high def cable box with high def cable.

it appears u have connected it to the epabx extension. when u try nos first & then press call, the unit dials the nos so fast that it does not understand ur access number (0 or 9) for dialling out.for this u need to give a pause between the access number ( 0 or 9 to get the dial tone for diallin an external no)this is available on the keypad as pause / redial & then out the number & press call.the prob should get fixed!

confirm that you select aux input in your soundstation2.-if your problem excit change audio cord between receiver output and the aux.

It needs to be plugged into a properly configured Avaya Definity digital port / wall jack. (NOT a regular telephone line as this can damage the polycom!!!) Does another Avaya digital phone work in that jack? If it does then call polycom for a RMA and eturn the phone under warrenty. If another Avaya digital phone does also does not work you need to check the PBX configuration or there is a wiring error at the jack or the PBX.

Sounds to me like a bad solder connection. I would suspect the crt filiments first, since you said it fades out. Could be bad solder connections any number of places.
