Can a CD player being close to a receiver or power amplifier affect its performance?

Sounds mechanical. Either too close to the speakers or you rattled it during the move.

It could be power related, but honestly not my first bet.

Thanks. Has glitches with speakers off. Tech checked out mechanical functions, lens , sled, etc. No issues there.

Move it back to where it was and see if it still has problems.

Thanks. We sold that house and only have room to place it where it is.

Thank you. I thought that might be a reason.Just wondered if anyone else experienced this phenomenon.

No. Your tech is obviously wrong. Disc errors? Impossible to be caused by anything but either the disc or the drive mechanism or lens.

Thanks. Yep, he could very well be wrong. Researching my symptoms.So far I have seen that EMF interference could be a possibility also.

Thank you all for your kind and informative suggestions. I moved the CDP and the problems have been resolved. I suppose the EMF was interfering with the CDP's functions.That or maybe heat?  Just curious. Would removing the CDP from the system and plugging it in- would the display indicate if it was skipping? IE- what would that look like.                                                                                                                                     Thank you so much again.                  

If the CD player has a current/remaining track time display you would see that changing erratically if skipping.

Wrap the digital player in copper mesh sheets to make a faraday cage around it. Will stop any digital hash from affecting your other gear. Cheap too. Fold and solder the seams. Crimp or folded seams don’t really work that well. 
I’m make a habit of doing this with all my digital stuff that isn’t already shielded, and with any shielded cables carrying digital signals; along with outbound switching power supplies, their power cords and output cables.

It’s really surprising how it will quiet down your system. 

EMF interference follows the inverse square law -- doubling the distance of empty space between two pieces of equipment reduces the interference to one-fourth of what it was before. Therefore, if that was the problem, often a small increase in separation fixes things.

Heat can also be an issue, but you'd likely notice the increased warmth if that was the issue.
