Good morning
I'm having a problem with my receiver Onkyo TX-NR636.
For those who know the usual "click" noise from the relays when changing a music track, changing input or simply pause/play a track on these Onkyo receivers, this is precisely the moment when my receiver goes to protected mode and shuts off. The diag function on restart tells a voltage error. Also note that when this happens I can hear a fairly loud cracking sound in the front left and center speakers (not on all other speakers).
This started to happen after nearly two months without using the receiver, stored in the house so no extreme weather condition.
What I have done so far to isolate the problem: inverted my front speakers (noise still appears on the front left output), inverted the front outputs (speaker and cabling inverted, noise still appears on the front left output), disconnected front left and center output (no noise of course, and somehow the receiver doesn't shut off, works normally).
Please note that I can watch a complete movie without any problem, no matter the volume level, for as long as I don't pause/play the track...
I suspect a problem on the center and front left channels. I have opened the receiver today and re-soldered all the soldering points on the outputs board. This did not make any improvement.
Do you have any idea of what component I should look at or test?
Thanks a lot for your help,
Guillaume
