Intermittent dropping of right channel. Sony STR V6

[MrBill—1]

I wanted to get a stereo for the basement and wound up with a Sony STR-V6.
It seemed to be in great condition and it worked without a hitch for a couple of months. It has just recently started to intermittently drop the right channel. This is certainly unacceptable. Where to start?

Hello there. and welcome to AK.
Not knowing your technical skills, I'd say start by re-seating your RCA and speaker connections. While you're at it, wiggle the RCA jacks just a little while music is playing. That's a very basic first step.

Checked the connections. I have 2 sets of speakers. Can run “A”, “B”, and “A+B”.
The issue is the same on both A and B.
Checked continuity of all wires. Hooked right channel speakers up to the left channel, they work.
Opened the cabinet. Turned on the power and everything worked then the right channel dropped again.
If I move the balance to the right channel only and turn up the volume sound can faintly be heard from the right channel speakers.
Guess I can start checking continuity from the speaker wire inputs back.
Would anyone happen to know where a service manual for this may be found.
I am not afraid to dive in. I have some mechanical and electrical aptitude.
Thanks!

I'd try working all the switched and controls to see if they are causing intermittent problems. Hopefully cleaning the controls will help

I need to drop this thread. I posted in the solid state section about the same issue.
I need to work with that one instead.
Sorry about that.
