Do the self check.

If you unplugged the set, plug it back, turn it on and allow to fail.

Press both the Menu and Input (input may be labeled device) buttons on the front of the set and Hold both for at least 5 seconds and release both.

Power light will begin to blink a two digit error code like 2 blinks, 2 blinks, pause and repeat it for a total of 5 times.

Let me know what error you find and I tell you the meaning and a possible answer.

Won't stay on


You're best bet would be to buy compressed air and blow out all dust and dirt that has made its way inside the receiver. If dust is clogging the fans it will overhead and shut itself off.

Philips 32" tv won't stay on


Quite possibly one of the heat sinks has come loose or a power supply cooling fan has failed.
Have you tried blowing it out using canned air?

My AVR 2700 standby light is on and will not switch over to digital. I have no sound!


If it won't turn on it won't do anything at a higher level of function.

Perhap it's self-protecting.

Generally speaking, an amp attempts to protect 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. 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 and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for
intermittent shutdown.
