Pioneer vsx 920 has recently began displaying amp overheat, switched off and unplugged at least ten times before connecting a usb fan to keep it cool but it continued to display the message. After around 10 hours it began working again, tested it by repeatedly by putting it in and out of standby mode and the amp seemed to be fine. Turned it off for the night and tried turning it back on in the morning and again it began displaying the amp overheat message along with the blue flashing light. please help
The real answer, sorry this is old -- is that a temp sensor, called a thermistor has probably gone bad in your amp. A thermistor is a resistance thermometer, or a resistor whose resistance is dependent on temperature. When these go bad in the VSX pioneer amps, the amp wont even power on with NO speakers connected to it. Just instantly goes into "im overheating, turn myself off" self protection mode. On some amps this part is easy to locate and swap out. Unfortunately, some are harder to find the physical location of this thermistor .

Hello,
Unfortunatelly your receiver has failed. The front panel is telling you one of the power modules is probably bad. Not an DIY type of repair. These parts are near $40.00, plus cost of replacing.
Look at options to replace your trusted receiver with a new one.
Good luck

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. 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.

Time for a repair shop to look, clearly the amp is down, it has failed. Have a qualified tech look at and get a repair estimate.
