I picked up an Onkyo TX-844 receiver from someone on Craigslist for $25 on Saturday.
The receiver is giving me some issues now, and I would like to try and see if I can crowdsource an answer.
When I set it up and on Sunday morning, the left channel was weaker than the right, was cutting out and producing a lot of static.
So, I pulled out the deoxit and cleaned the speaker terminals and that helped give me a stronger left channel, but it still got static. I next cleaned the Volume knob and the balance knob with Deoxit. This also seemed to help, but wasn't 100%.
Next, I cleaned out the RCA jacks on the back and that seemed to help a LOT. The thing sounded great.
But that did't last all that long. If I power it off and back on or turn off speaker A and turn it back on (from the speaker selector switch), the static will come back, and the left switch will cut out.
The only way I have been able to fix it, is to crank the volume to about 50 percent and lower it back down to an acceptable level. That has always fixed it and brought the left channel back to normal.
I think a good first step would be to give it the full deoxit treatment and see if that fixes anything.
But I am curious if these symptoms are indicative of any kind of major problem that a Deoxit treatment may not fix?
EDIT: Yes, I did test the receiver. But I tested in his living room with the volume cranked up much louder. Which is when it works flawlessly. Also, I am sure the owner would probably refund my money, but it was only $25 and I drove 40 minutes to get it. An hour and twenty minutes of time is worth more than $25 to me right now.
