I just purchased my KLH R3100 and shortly after 5 days the left channel became scratchy and really annoying and the volume coming from it would go soft then high and then would continually go in and out of the scratchiness. It did it once before so i replaced the speaker wire and it worked fine but now its doing it again. What should i consider doing next?

Its sound like you have dirt, dust, some kind of containments in the volume controls of the unit are their separate vol controls for left and right id say if you could try some electronic spray contact spray and as you spray have maybe another person help you by working all the volume knobs full right full left or full up and or full down, If this help but doesn't solve you may need to remove and expose the circuit board inspect for loose or cold solder joints..Im not sure your make model year etc, But dollars to doughnuts most likely that would be my next plan off attacking the problem. Well im so sorry I hope this helps or at least leads you down the right path.
Replace center channel speaker with known good one. If no longer scratchy then the voice coil of removed unit is rubbing against the magnet pole and the speaker needs to be replaced. If the replacement speaker also sounds bad, then the amp for the center channel needs repair.
If the device in question works OK without being shook etc, then all the problem is a bad soldering joint somewhere. You can trace it by following the speaker wiring of the left speaker inside the amp. You might need a magnifying glass to spot it. If in doubt just apply the soldering iron to a suspect joint. You might not need even to add more solder. Check around anywhere where screws fix PC Boards as the board can crack at these stress points. Sometimes breaks occur if the device has been transported somewhere.
If you are on cable, first run the cable wire from the wall directly to the TV, eliminating any cable box and/or VCR. If channel 2 is snowy but the rest (especially 3-6) are clear, it is most certainly a cable problem and not a TV problem. The TV uses the exact same circuits for channel 2 to 6 (VHF-LOW) so if the tuner was bad and 2 was snowy, 3, 4, 5 and 6 would be snowy too. Bring a second TV into that room, disconnect the cable wire from the RCA and connect it to the second TV. Is channel 2 on the second TV as snowy as it was on the RCA?
Sorry to inform you, The driver transistors or IC is going bad, or there might be a poor solder connection on the center channel Amp. If you know how to solder, you may be able to poke around at the center channel amp circuit, with a wooden or plastic tool, and maybe see where the bad connection(s) are. To get a shop to looki at this unit, may not pay, but that is all up to you, on how much you paid for the unit, and how much your willing to pay to get it fixed. Read this great article and see if it helps you to decide. http://www.techlore.com/article/10602/How-to-Determine-if-you-Should-Repair-a-Broken-Device/
