Ultimate stereo nightmare


I have a complex stereo system, having accumulated many various components through the years. I also have an impenetrable jumble of wires.  Until now I’ve been able to deal with problems that arose. Now that I am elderly I can’t easily get down on the floor to assess things. I bought and installed new very expensive speaker cables (Audioquest Robin Hood), and subsequently found that my right channel was not working. After switching cables, the right channel was still not working. So the problem is somewhere in the system.  I don’t know if it’s a loose cable or something else and have no way of tackling the jungle of wires to check it out. 
I hired a company that claims they deal with these things, but there’s such complexity I don’t know whether they can deal with it.

Same boat here. Harder everyday.

But it is worth it to "refigure" everything out. 

And make better notes to self.

If or when you figure it out, write it down, at least on the phone.

Totally recommend putting all the complex crap up for sale and going with simplifi, an active speaker setup with everything needed built in:

I agree with @kota1 . At some point, it’s better to simplify (and SimpliFi is a good resource). Do you really use all those components, or is it just "nice" to have them? When (if not now) does "can’t deal with all this" outweigh "nice"?

Well, whatever you decide, I wish you the best of luck!

With a complex system it's always best to have full access to the back of your gear. Best you can do now is try to hook up a minimum system configuration and see if you can get the lost channel back. Most likely a wonky RCA connector or cable. 

Best eliminate one by one, only way to do it, may take time but would be good for a fresh start. +1 @russ69 as having full access to back of gear.
