You may also consider redoing the potentiometers on the main PCB in the deflection area. If one of the legs has broken free you can get the results shown on your monitor. The Real Bob Roberts arcade parts web site is a good place to get replacement parts for your Tempest. Only work on your pcb if you have good soldering skills. Ive seen a lot of hacked boardsets.

Bad capacitors most likely, buy a Wells-Gardner 19K6100 cap kit and replace them.
