Picked up a new cab last night Dynamo H-5 not sure what model chassis it is yet but the picture looks great except for these horizontal grey lines that scroll vertically pretty randomly. the lines are straight and roll fast and some times very slowly.
my first thought after trying to adjust it was it might be a grounding issue, so I ran a wire from the Earth ground off the power supply to the chassis, but that didn't do anything. the power supply I'm using is old and came out of my TMNT cab when I first got it so I'm not too confident in that power supply.
the other obvious thing would be to re-cap the chassis, and look for bad solder joints but the chassis looks brand new. there's a tag on it that Playdium (arcade and dealer in toronto) had it serviced just in July 09. so I'm thinking I should try replacing the power supply? anything else I should look at?
