Rogue Pioneer SX-828

Hello good people -

Once again my SX-828 has me foxed, and although I know that weak LH channel issues have been previously posted at length, I cannot find one that replicates my own.
Yes, the LH channel is weak on both speakers and headphones, and I have used Deoxit on all switches, pots and anything else that would accept it, to no avail.
So, before I began a dreaded major stripdown, I listened one last time on headphones and heard the familiar strong RH channel with negligible left. However, as I removed the phones the whole situation reversed - strong left, weak right. More Deoxit and frantic to-ing and fro-ing on the headphone jack didn't help, and the problem, and the same symptoms, persist.
As I have mentioned previously, I have limited skills and even less knowledge of electronics, but I would be delighted to receive any suggestions as to the possible cause and remedy.

Did you clean the protection relay contacts? Most of them have to be removed from the board for proper cleaning. Then remove the plastic cover; use a stiff piece of paper to clean the contacts (the contacts to clean are the ones that aren't touching each other; normally open). I usually force the contacts closed with a piece of paper wedged between them, and move the paper back and forth.
Could also be poor solder connections. Does the problem change when pushing on the circuit boards?
