Question about Onkyo Audio Players & Recorders
I have a onkyo tx-ds747 and the cooling fan is not coming on. but its works fine
maybe you have defective power transistor output and this is shorted, or the problem is in the power section like shorted diode shorted capacitors or open circuit may cause this, and the STK IC if shorted you got protect warning..

What it sounds like you are describing is the protection relay turning on then imediately turning off for the time period mentioned. That would indicate a possible short in the circuitry. Probably a capacitor that is intermittant or even a transistor about ready to fail. This is probably not something you can look for if you are not an electronic tech. Find a reputable shop and get it fixed before it quits and does more damage. Let me know how you make out.

you may want to try a factory reset by pressing and holding vcr1 button while pressing the power button. do this with the unit on. It will reset back to factory default. so any saved setting will be lost and you will have to set again to your settings.
