When I switch on the amplifier, all the source input LED in-put source indicators lights up. No sound comes out, as I cannot select the input source as all the LED lights are on.

This happened when I used my amplifier after 2 months.

Please advise me how to get over this problem and what should be the reason.

This is one of the common problems of this AMP. The selector switch is controlled by a micro processor controller IC TMP47C200BN which goes faulty. Unfortunately this IC is hard to come by. Best of luck
