I am helping put back together a Twlight Zone pin that someone took apart over 2 years ago. The playfield was cracked from beening droped in shipping. The one that took it apart fixed the playfield and did a good job at it. But he left and the rest of the playfield was left in boxes. 2 years later I was asked to put it back together. So with having no pics I started. B(1) 0 15 and now in game play it will show a snap shoot of your score and will stay like that for about 10 min then might change and do anouther snap shoot. Soon as I change to menue it works just fine.

Ive done all the volt checks and there just fine, reset all the chips, checked for cold solder on the back of all the boards, repluged all the plugs. Im at a lost on this one. Oh and I did swap out the display from anouthe pin and same.

Please help this is the olny place I can think of that has a place for all the smart pinners out there.

Sorry about the first post I did it on my phone and somthing got lost, so I'll try again.

Ok... The help I need is with the display. The dot matrix only works in the menu mode and not in game play. I replaced the driver bord with a Rotton Dog board and I swaped out the dot matrix with a known good one and still the same problem. The snap shot I was talking was about the display. Durning game play about 10 min or so it might show your score and if your lucky it might show it again. I have heard of a slow display but this is not that.

I did a burn in and at the end I got a Page Error B(1) 0 15 but no other errors on any of the tests. I can't find what the page error is.

I guess I'm lucky in some ways though, all the normal issues that people have with this pin are working, optos have been fixed, clock works, gumball working, min. play field working, lights good to go, and sound works. I have fought my way through thoughs but the dot matrix problem is got me stumped.

I have reset all the chips and cables and checked all the pins. Wondering if an updated ROM chip will help. It still has the ones from the factory in her.
When I first started this project I found some of the plugs had wires in the wrong spots like one wire moved a pin over to a spot where there was no pin on the board.
Is there a ROM chip on the main board that controls the display driver board that might need to be changed?

The only place I've seen the ROMS have been for 25 bucks a pice. I don't have a way to reprogram them? Communication issue? Are you talking about the ribbin cable from board to board? I might be able to swap from a know good pin I have.

I hope the driver bord is OK it new from Rotton Dog. It test at all the testing ports with in specs, the old board all the high volts side of the board died.

Yeah every time in the menue I can be in the middle of a game and nothing on the dot matrix and a soon as hit the menue the dot matrix works.

Changed all the ribbon cables and problem went away thank you for the help!!!
