Hi all,
I have a Black Rose pin that is having a DMD problem and I am at a loss on how to proceed. The issue is that some dots on the display don't light up however, it isn't always the same dots. The missing dots are different for each screen and sometimes different for the same image during different cycles.
Also, it only starts after the pin has been on for about 30 minutes.
I've read through everything at pinrepair.com and I have done the following:
-Swapped out the high voltage dot matrix display controller board for one that is verified working
-Swapped out the DMD display with another that is verified working
-Reseated and cleaned the pins of the ASIC chip on the CPU
-Reseated the ribbon cables
The problem is STILL there.
The only other things I can think of is to replace the ribbon cables. Is there something I'm missing? Any and all suggestions are appreciated.
Thanks!
