Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00
I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes.
The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.
