No sound from speakers

SOURCE: KLH R3100

Try pushing the speaker button under the power button on the front.

The only way your surround sound will work is if you have either the coaxial or fiber optic digital hookups attached to a PS3/Blueray/DVD/Cable box/Satellite box that have digital sound outputs. If you are just using the 1970's version of the red/white audio cables that is stero only.

HI pull down the flap on your amp and you will see buttons for zone 2 settings,press zone2 then level up this should work.

Like I wrote, I had a similar problem with popping and then no audio for an extended period of time. I found the solution on another site, http://dexsoft.com/blog/?p=15

Apparently the solder joints are weak, and just as the blog described when I opened up the receiver I saw the same scorch marks from overheating. Just as the blog described, I added solder to each of the joints in the photo and have had no problem ever since.

I am no solder expert, this is my 2nd time, but all I did is build up each of the joints and I have been listening to music, playing movies in surround sound with no problems, no popping for the last 2 weeks.

SOURCE: Can get either 1 or 2 speakers working at the same time.

JimRod80,
You say you change theaters which is different than what I propose. Have you tried the "SURR MODE" button on the front or on the remote? the only mode I use is prologic. it has all speakers in surround and doesn't sound like you are in a cave.
