Chony,
Sometimes one of the amplifiers just 'dies'(one channel) or in case the L & R amps have a fuse of 'their own' one of fuses can be blown.

Perhaps I missed it, but does your headphone sound OK on both sides ? This is important to know.
If the headphone sounds OK : Please try to switch speakers first before starting other actions !
