I have been looking for a Mortal Kombat one PCB and found one this weekend. Actually a friend of mine gave me a MK1 pcb (no audio board). He said he didn't think it worked, but I might get lucky if I pull and seat the chips. So I pulled, cleaned, and set the chips. Plugged it in to my Great 1000 Mile Rally cab and the screen is blank. I pulled the pcb and plugged my Time Killers in and got a blank screen. I know my Time Killers worked a couple of weeks ago, but I sold the cab that it was in and the MK1 cab I have is currently empty waiting for me to paint. Did I miss something? Shouldn't my Time Killers at least show a picture? Thanks in advance for any help.

Jamma is interchangable. so if it isn't working then there is something else wrong.
Rule 1: Check power supplies.

It does on the solder side, but not on the component side. No sound either Ian.
