I purchased a 2-slot MVS cab about three weeks ago, and recently discovered it had a badly frayed power cord. So, I asked the seller (E.C. Amusements outside of Philly) to drop by and replace both the cord and the power supply (just to do both while he was visiting). He came over today and did just that... brand new China-made PSU, along with a newer, non-frayed cable. But then, things started to get weird.
In only have a few games... Bust-A-Move and Neo Turf came with the cab, and I recently got Sam Sho II and a new-old-stock copy of KOF 2002. And while all of the games seemed to play just fine before, now, I'm getting screens that look like this:
And also this:
Sometimes the 1 and 2 player lights flicker, sometimes the screen displays nonsense blocks of color and light. All very weird.
The tech said it was a case of dirty contacts. He told me to lightly sand (using a very, very fine sandpaper) each of the contacts on the games, which I did and then used ispropyl alcohol to clean and remove any loose dust. The tech is long gone, but none of my games play now... even though they all played fine before.
Is this a case of contacts on the mobo suddenly getting dirty and causing things not to work? Is the Chinese PSU causing weird issues? Any thoughts or advice would be appreciated.
