Pin2000 uses a standard res (cga) monitor. If your LCD is a standard PC monitor it won't sync down to CGA.
You've got a few choices these days, first would be to get the original repaired. Next, you can swap it out with virtually any standard res tube type arcade monitor. Changing monitors usually requires swapping the monitor frame over to the new monitor as Pin2K used a very compact and oddly shaped monitor frame. You'll also probably have to mod the video cable for the connector on the new monitor. Lastly, there are now multiple options for open frame cga (multi-mode actually) lcd monitors. Virtually all of the big distrib's carry them now, they can also be found on ebay. You'll pay a premium though, they aren't cheap. With this option you will also have to fabricate your own mounting, no big deal really.
