You either have a cold solder connection on the vertical output IC401 or a failure of the Vertical output IC altogether. The part number should be labeled clearly on the front of the chip and is likely LA7836 or LA7837. It's difficult to reference parts on a set this old. Remove the chassis and visibly inspect the solder connections. If they look good, replace the chip. Good luck
