My Pioneer Receiver Shuts Power OFF within 10 seconds I put it on.

Hi Sharad! Do this maybe of help. Turn the power off. Wait about 10 seconds, then power up again. Get close to the reciever and listen for a click-not from the speakers,from the recievers itself.If you hear a click, you can assume that the power supply is ok for that circuit.This does'nt eliminate the power supply problem but it will do for now.You would have to check both the positive and negative voltages from the power supply to see if both are present or if one or both are missing. This would be dc voltages and the positive voltage must be equal to the negative voltage ,if one is higher than the other, the regulator transistors in the power supply maybe defective. The transformer can be checked for AC voltage before the power supply.You know that the secondary is good because the dial lights. For this kind of problems you better change the regulator transistors with desame number.
