Where do you find those boards?  I've googled them and I can't find any for sale.

Figured I'd put an update here so that when people google this 10 years from now they might find an answer Tongue

The shifted video is caused by a corruption in the game board (B board in CPS2), and the striping is caused by a defective A board.  When I replaced both A/B boards everything worked in its entirety, then when I took the old game into the new board I had shifted graphics, but no striping, and vice versa resulted in striping, no bad graphics.  Getting the board phoenix'd might fix the game since I think it's probably an issue with the game data being corrupt.  But a lot of this is just speculation, I don't know enough about how to remove the parts inside the board itself.

anyway, hope that helps anyone who encounters striping or graphic shifts on their CPS2 games.  That way you don't waste hundreds of dollars buying stuff to troubleshoot with.

Hi everyone,

Losing my mind a bit over here.  I've had this game sitting around my house four a couple of years now.  I bought it in around 2012/2013 and it worked for a couple of weeks then crapped the bed and started having these issues with vertical stripes down the screen and random graphics being messed up like the right side is shifted over onto itself.  Currently I have replaced the power supply, added an extra video adapter to test whether it was a monitor or game issue, replaced the wiring harness, and still am facing the same issue.  I've checked both A/B boards for damaged pins and everything seems straight and fine.  Currently I have the original board in, and I also have another blue version of the same game but that one won't even load and gets stuck at a blue screen with boarders.  Possibly a dead battery that needs to get phoenix'd, but that's semi unrelated.

So after a few days/weeks/years of pulling my hair out, I come seeking help, any and all appreciated.  on the bottom is a youtube video showing the issue I am currently experiencing so you can see for yourself.
