I have a shaq attaq pin and the display went out. These are the thing I know and have checked.
-I am missing -112 vdc at pin 1, -110 vdc pin 2 and the +62 at pin 8 on A4J1
-Fuse F3 and F4 are good.
-I have continuity between pin 4 of A4J1 and ground
-I have tried a different DMD, no change.
-The display controller board flashes at even rate, so +5 is good???
-I replaced R16 when I bought it and it looks good but did not check it.
Is there anything else I need to check? Do I need to rebuild the high voltage on the controller board?
Thanks for the help.
