Why does the receiver turn off after pushing the power button on?

So when I turn on my Receiver from Standby mode it briefly powers on then makes a signal noise error like you are watching static television then the Receiver turns off and a Red Ring flashes around the Power button. I have tried opening the tv hutch door where the Receiver is at to give it more ventilation because I think that could be a possible culprit. Does anyone know anything specific to this brand or model?

It can be a speaker wire connection, pull one wire at a time while switching the unit on and off.

Sounds like the unit is going into protect mode. There are a few causes for this. First unhook all the speaker connections. If it stops doing it then, there must have been a short in your speaker cables or speakers. If it continues to go into protect mode you either have a blown power amp or blown power supply(maybe a bad digital boards, but thats highly unlikely). That will have to be serviced by a professional. If the unit was not receiving proper ventilation to begin with chances are it overheated and it caused the current failure. Sorry to hear about your issues, I hope you fix them.
