Onkyo AV receiver repair- TX-NR838

[@r.v.l6051]

I have same model, sometimes shuts off, when it’s on no sound! Any idea?

[@avproservices4708]

You try to check the speaker channel. The amplifier works hot making the circuit to burn

[@avproservices4708]

And no sound maybe firmware error

What was the issue with this?

[@avproservices4708]

Firmware fail

I have one....great Receiver.....but I have a problem now, the front left speaker and the Right Surrond keeps poping (weird sound, like crakles) but only when voulme is at 70....and after 1 hour it turns off and goes into Protection Mode. Only if I reset the Protection Mode it turns on again....any sugeation of the cause? Thanks

This cause may be come from Pre-power amp (class a) board, check the trace of the pre-power amp(class a) board
