Onkyo TX-1500mkii no right channel
I'm troubleshooting my parents Receiver and the right channel is not working. I've swapped speakers/cables and problem is right channel. Balance is in middle. I've checked the fuse and it's blown, replaced, and still no right channel. I've cleaned the Pots on the front, volume, channel switch, and all others. Scratchiness gone from volume control, but no right channel. The unit is pretty clean, blew the light dust off but overall it's been in a cabinet and not used all that much.
I do get a click when switching the speaker off-A-B selector when passing by A which is the channel the speakers are connected to. I've checked over the board and no leaky caps or burned parts. I read that RL101 Relay can go bad but I cannot find that relay on this board. I'm not even sure what it looks like but know most relays have a housing and contacts inside but cannot find anything resembling a relay or labeled RL101 on the PCBAs.
I'd like to check out this relay. I'm also going to get a signal generator or a pre amp signal I can feed to the power amp to see if it's working and not the pre. Not a tech but can get help at work (electronics contract mfg)
Any help locating this relay? Any other things to check?
Thanks for any guidance.
