Amplifier Repair

[MikeKrz]

Hi All

My Onkyo amp TR-838 has lost the left channel. Replaced cable and switched speakers so it’s definitely the amp.

After leaving it on the test signal for a long time the channel came alive again. But after I switched on and off, nothing again.

Is there a good repair shop for AV equipment that the forum would recommend?

Or any ideas how I could fix this?
