polo 1 or 2?what frequency is the game board 15k or 25k
if the game board is standard 15k then check the following
if its polo 1 then you vertical hold is wrongly set,check it again
if its polo 2 then maybe its set to 25khz instead of 15khz on the jumper plugs

Still no luck  Any other ideas? Its a polo 1 monitor, and standard 15k game board.

whats the history with this,did the game just go like this or have you swapped a board or anything else?

It was working fine, and then all of a sudden just went like that. It was repaired about 2-3 weeks ago, supposedly two caps on the horizontal output were changed. Thats all I know.

there are a couple of caps, transistors and an ic that can cause this sort of problem but its very rare,look at t110,t112,c149,c150 and ic 104 and the only other possibility could be a faulty vert hold pot
