Hi;
I am troubleshooting my Space Duel and have an issue with the display.
The game plays blind 100%, coin up, sounds, controls etc but the
display is limited to the upper left quadrant of the CRT and instead
of the normal items that should be displayed, I have what looks like
an oscilloscope output:

I swapped a working boardset and the game plays perfect so the problem
is with the PCB.
Any hints on how to proceed - what to look for??
Thank you
