Question
stand by flashes.then  the receiver stops.what can be the cause?thanks

Answer
Could mean that the receiver has an internal problem or that there is a short and it's going into protection.
Carefully check the speaker output cables on both the amplifier and speaker end to make sure that the + and - cables are not touching.
If the receiver is older that 2 years and less that $500 it may not pay to fix.
