I got a Commodore 64 for Christmas and I am quite pleased with it.
However, I do have a problem which I wish I could correct. The screen
image has a wavy appearance. A wave of horizontal displacement, with
an amplitude of about 1/2 a character width, traverses the screen from
top to bottom with a period of about 2 seconds. This gives the appearance
of looking down through water. I checked the grounding, and found good
continuity between the ground leads and the wall socket ground. I checked
it too and found that it is really grounded to the plumbing.

My suspicion is that this wave is being generated internally and being
fed to the RF output. Can anybody help me on this?
