I think this is probably a big coincidence...

I recently ran into an issue with a light line showing up on lighter/white backgrounds on my plasma TV. This seemed to happen after re-connecting another APC - UPS (1500 V), other than the one that I had been using. Both were "used", but the last one connected was "newer" than the previous.

Is there any way in hell that this (using a UPS) could cause "burn-in"? I would have to think not, but would rather be positive before using another one on a new plasma display.

Thanks!
