Can someone please tell me whats wrong with my police trainer board?

The picture looks like this but it still plays and has sound. Please tell me someone had this same problem and how to fix it.

Looks out of sync.  Have you tried adjusting the monitor?

[berlincam86]

yes ive tried that.

Also check to make sure all the chips are seated well on the PCB.

Could very well be a monitor issue as well.

Did it just stop working or did you pick it up this way?

[berlincam86]

I picked it up like this. Ive tried 2 sets of chips. Differant monitors and differant power supplies. All made the same picture.

Have you swaped Processors yet? (If you can)

[berlincam86]

no i havent tried that but why would that make it play like it is. The game plays fine its just the video is screwy. I have changed everything that i can unplug and plug back in. I havent tried to solder or unsolder anything. Mostly everything is surface mount.

thats a strange screen,its like none of the colours are syncing at all.
what monitor are you using and what are the connections pinouts you are using?
have you tried the cab with a different game board?

[berlincam86]

Well so far im using a test station i built with a rgb to rca converter to play it on my tv.. But where i got it from it played the same on a differant monitor. Im using standard jamma pinouts.

KLOV says Police Trainer is standard resolution.... can anyone verify if that is correct?
(I thought it was a medium res game)

Definitly a sync issue.
Whether it's due to wrong resolution settings etc or a bad video output on the boardset I'm not sure.

Definitely standard res.  Most of the ones the company I worked for had were in Mortal Kombat cabs with K7000s.

there is a polarity switch on the board  for sync but it does nothing.

[berlincam86]

Ok I fixed it. It was a combination of the sync switch and the voltage. I switched the sync switch and played with the 5 volt adjust on the power supply and after a couple of minuites its working great. Thanks for your guys help.

Ok nevermind i have a break somewhere because when i touch or move the board it goes all fuzzy. I can see nothing but when i move it again or push in the right spot on the board it goes back clear. So i have to find the break or loose joint.
