I had to replace mine and went with a Rottendog.. It has worked perfect since installation. I think it cost me about $70. Not sure if this helps.. but it's a good alternative to a hard to find in good condition part.

The machine i used the rottendog in is a DE Star Wars.. like i said it has been nothing but perfect.. I have been very satisfied.. However, I am not a electronic expert and i appreciate all the information here.. I'm new to this stuff and at the time the reviews were nothing but favorable about the boards. I will be looking into pinscore as well!

Could the previously named PS be responsible for my problem being discussed here?

sorry to bring back an old topic... but i had to share my advice..
I just replaced my aftermarket board named above with a rebuilt original. What a difference! The table plays so much better, the flippers hit harder, the pop-bumpers slam hard! and everything is WAY brighter. Even my DMD problem is fixed. I take back any recommendation i had made.. It ended up being a waste of hours and money.
