Graphics issues are typically either a problem with the custom chip on the A board (not fixable) or the mask roms.

Check the mask roms against the MAME set. Check the sockets for any damage or cold solder joints.

Test the A board with a known good B/C set (from any game).

In some levels I have this kind of problem , in others works 100%. I check the mask rom.

Considering how graphic faults are so specific to certain areas of the game I'd say one of the graphic mask roms are bad. I would test the game without one of them, checking each time which make the faulty graphics fully disappear when removed.
