RS had a Display issue with Vertical Lines appearing at some points and disappearing at other points.
IN DMD test 2 pages had errors.
Replaced all ribbon cables no change.
All voltages good
Aftermarket Pinled DMD controller board is what is in the machine. Maybe Bad?
Replaced the Ram Chip with a Ramtron
Now the machine will not boot with DMD Ribbons connected to Pinled board.
Machine will boot with Frozen static on DMD board with J601 only disconnected to Pinled Board.
Machine will boot but with Dead Black DMD with only J602 connected.
Any ideas? Is it the wrong Nvram? Bad WPCS chip or Pinled chip?
If bad WPCS chip or chips which would they be ?
I do not have another WPCS machine to swap boards.
