The dotmatrix display on my T2 has on and off scrolling. I assume the problem is somewhere on the dotmatrix controller board. I tried reflowing the solder on j604 and now it seems to be scrolling all the time. Any suggestions?

To be more clear the whole screen is not scrolling there is lines going through it.

Replace the two large electrolytic capacitors on DMD controller board.

I replaced those two large caps and I still have the same problem. It’s not fully scrolling there’s just wavy lines scrolling through the display. Any other ideas?

That really sounds like a capacitor problem. Are the DMD voltages correct? Take care when measuring at the connector and do not short anything with the meter probes.

Visit Pinwiki and read the WPC DMD section

The first thing I do when there is strange behavior on the DMD, is to reseat all the ribbon cables in the backbox, and most of the time that actually solves the problem.
