After a recent move, noticed my right, front speaker channel doesn't seem to be working anymore. tested it with a couple sets of speakers, but no luck. also, i tried hooking the speakers to the 5.1 channels. all the channels work, except for the right one. Any suggestions?

I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.
Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.
So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?
It seems that the main sound processor comes into an error and so seems a fault on the board. Since checking for a component level solution is very tricky as the access is not friendly, what could be done initially is to remove and reset the boards, check for faulty connectors that seems to vibrate and bring in these faults. Check the solde joints of the connector pins on the board. Check and solder the processor IC and the allied circuits. If the fault seems to disappear when the set heats up then you must check using a magnifier.Check the solder on the audio driver outputs of the center, main , front and rear are clean. If not refer and proceed with consensus as a false move can cripple the set.
How you power off the amp won't hurt it generally. I used to fix ONKYO amps under warranty, and I can tell you now, it will be full of dry solder joints. Take you unit to your local repairer, and they will resolder all the offending PCB's inside. This type of repair will fix 99% of strange audio noises and cutting in and out etc. for ONKYO recievers. Otherwise this is quite a good product.
Swap speakers over...check the balance isn't fully to the other channel...swap left/right phono cables over (if thats how your using it) other than that i would say is broke.
Easy way to check speaker cable/speaker... touch a small battery (like used in a remote) across speaker wires, you will hear and see the speaker cone move.
very basically try swapping over the speaker cables, if this doesnt work i suspect you are in need of a new ouput i.c. these can go if the speaker wires are touched together, unless there is a protection circuit.
if you are using RCAs as inputs to your amp.Swap the R to L @ RCAs to see if its comming in okay from radio.If both RCAs have audio then amp is bad ,If amp has any type of switches , move swithces to see if it comes back .Also if both RCAs inputs have audio .Move the RCAs when connected on amp to see if amp has bad connection in board to RCA jacks..If audio comes back on bad side when jack is moves .Then you have bad solder joints on board..If not then you must have bad outputs on amp..
