I have a hard yardage PCB that I got from a fellow klov member, a while ago. I try it today , all i get is a black screen. I try tmmt and it works fine. Any ideas what it could be wrong with it ?
 
Check and make sure your cabinet has +5,+12, and -5. I don't know specifically for THAT board the power requirements, but I have seen a lot of games where it functions perfectly fine with one boardset and not another and it is usually the -5V rail has died in the switcher.
