Sony STR-DE935 Receiver

I was given a Sony STR-DE receiver from a coworker who was upgrading his system. One problem with the receiver is the left rear channel cuts out sometimes and the only way to get it to come back on is to crank the volume up loud for just a second, then it works ok. Any ideas on what could be the problem?

Also, it is out in my shop/cave, replacing a old MCS receiver. The sony has surround, the old MCS was just a 4 channel stereo which sounded great. The sony sounds great watching something with surround sound, but when I plug in my mp3 player, I don't get good sound out of all 4 speakers like I did with the MCS. Just out of the 2 fronts and the sub woofer. Am I missing a setting or something?

Thanks for any help with either problem.

There should be a sound field adjustment.

This is the link for your manual. Page 32 explains how to setup the sound field which is the adjustments for the delay and audio processor sections for each input.

As far as the problem with the speaker......try swapping the speaker on that channel with the other speaker. Just swap wires at the receiver to test.

The problem is not the speaker, it is the receiver, it is the same problem the previous owner was having with his speaker.

Then there is a problem in the output amplifier for that channel. Might not be a do-it-yourself fix.

A cold solder joint could cause the output to behave that way. Take the unit apart and (with the power off) touch up solder joints working backwards from the terminals. You may get lucky.
