Sounds like the AVC circuit isn't working right. When you do a re-cap, there is a can under the chassis for the AVC (both RF and IF). Inside, there are some paper caps that do need to be replaced. Removing the units to replace the caps is a bit tricky. I would certainly make sure all the caps int eh circuit are replaced and then check the alignment including the AVC settings.
