Wells Gardner D9200 with a vertical deflection problem

Looking at the picture the bottom inch and half is black, the vertical deflection is not filling the whole monitor.

The best thing to do first when you have a problem like this is to start with a cap kit. Caps are normally the first components to die, they over heat in the cabinet and dry out. Replace those fans on your cabinets people when they brake, monitors will last a lot longer if the machine stays cool on the inside! Cap C388 next to the vertical IC was bad.

Cap C466 was also bad, next to the flyback.

I put the chassis back on the monitor tube and the vertical deflection problem was fixed!
