Sounds like a convergence problem. I had the same issue. I got a repair kit from the folks at TvRepairKits.com. Worked great for me and saved a ton of money.
The zenith part number for the convergence out PWB is 6870VS1531A thats a small skinny, is that the board he took or did he take the large board on the left side of the chassis looking in the rear?
Your convergence amp ICs are bad. You will need to replace both of them. Its an easy fix if you can solder. Check the resistors right next to the ICs also often 1 or 2 of them burn open when the ICs go out. Let me now if I can assist you further.
