I have my stereo receiver hooked up to the TV, DVD and CD players. The sound for all has been great, and still is for the TV and DVD...but when I play the CD player the sound is somewhat distorted. It's worse in one speaker, but it is distorted in both. I can play the TV and/or DVD very loud with no distortion at all? What could be wrong with the CD player? Does it just need a cleaning? Or is there another possible problem? I don't want to spend a ton of $ in repairs...I would rather just replace it. Please help?!?!
