Pioneer Laseractive troubles...

[Vectrex28 | 366]

First off, IDK where to put this since there doesn't seem like there is a category dedicated to repairing video game systems, so I'll just put this here.

Anyway, my Laseractive seems to be resetting quite a bit. It seems to happen more often if there's a PAC inserted.

I'm suspecting something in the PSU might be at fault (I checked for 5v coming out of the PSU and it does seem to go down every so often when a reset happens), despite it having been recapped. Does anyone know what we're dealing with? Here's a video of the issue

Any help will be greatly appreciated
