Crt problem

[Pharo]

Hi all I'm wondering if anyone can help switched on my leisure 2000 jamma cab to have a wee game of bombjack playing the game of my life when I noticed the top right corner started to drop down a wee bit then more of the top area started droop down over the space of ten mins till it eventually turned to garbage like in the pic.
Any ideas would be appreciated.
Cheers Brian

Looks like you've lost sync. Try tweaking your horizontal and/or vertical sync pots on the monitor chassis. You need to ideally find out if it's a gameboard fault or monitor fault though.

Cheers thanks for the reply will play it again and see how long it takes till it happens again then swap it out for another board and see if it does the same 👍
