HELP: Data East Score Display

[dbpbandit]

I've got a strange issue on my Simpsons pin and could use some help. I purchased a LED score display from Rottendog a few months back and everything works with the exception of the lower half of the bottom row on the display (see pic) I worked with Jim from R.D. and he had me send it to him, however it works fine on his end so the problems on my end. Any ideas of where I should start looking to fix this issue? I've already ruled out the ribbon cable and other connectors but any suggestions are greatly appreciated, thanks.

my guess is one of youe ribbon cables is backwards .

I'd guess you have a problem with the display controller board. Pinrepair had a pretty extensive write up on troubleshooting such things but it is of course now gone.

what makes me guess about the ribbon cables being backwards. I had the same kind of thing with my Pinled Display when i installed it into my Fire machine.

There is a Red Line in ribbon cables you need too match that with the other one .

one would think if the ribbon cable is bass ackwards, the whole display would be funk-a-doodled, maybe not

PM me your email address and ill send you the pinrepair section on troubleshooting the display

with my fire machine that was'nt the case . Display was messed up only in certain spots.

Yea, I went through the whole ribbon cable checklist, no change except when I actually DID hook it up backwards - then it was really messed up.

UPDATE - I ended-up sending my MPU and LED score unit to Huck's for repair. He was able to fix it and now it works great. Huck was great to work with and a fast turn around time.
