question about jvc receiver
 

Hi
First time post, long time lurker.
I have a jvcRX950v stereo receiver that I have been troubleshooting.
the left channel is distorted but comes back in and plays both sides great
for 2 hours, then it starts distorting again and basically, it is in and out
from there.
I have fiddled with a few wires but no go as I suspected to be a short or
something.
there does not appear to be any burnt parts or anything, and I have tried it
with 3 different speaker setups, and now have it on the bench with just
headphones.
I am getting the same results every time I power it on and still no luck in
tracing the problem.
any help would be definatly appreciated.
Thank you for your time.

Bad solder or other connection, dirty controls, output transistor failing -
no way to know without actually doing the troubleshooting.

Thanks so much for the tips.

I dont think fiddling w/ the wires is gonna get you anywhere...you
probable got bad solder or peanut transistor in that channel...freeze
spray could help isolate....the biggest advantage you have is that the
other channel is fine. Swap suspect parts w/ other channel until
problem follows.

Ok thank you I will try that also.
