Hi Guys,

The DMD in my CFTB has suddenly stopped working. No dots or signs of dots at all.

Machine seems to be functioning fine otherwise, flippers work, etc.

I took the DMD itself out and tested it in my TZ and the display does seem to work fine.

After reading here, I checked the fuses and don't see any that look bad. I do know how to test continuity and tested the fuses on the dmd driver board and also F116 on the driver board and seem to have continuity there (I also checked other fuses but not all of them).

I also looked at the purple connector in the lower cabinet (another possibility mentioned here) and it is not loose.

Hopeful that someone here can offer advice.

I know that folks often suggest testing for voltages when offering advice but I am ashamed to say that I don't know how. I have a multi meter (see photo) and would be happy to test if some kind person could tell me how to set the dial and where to plug what.

Many thanks in advance!

Hi Guys, Thanks for the advice!

Because I have a TZ, I thought it might be more prudent to just check and see if the DMD controller board from it worked in my CFTBL and vice versra.

CFTBL DMD board in TZ: No DMD
TZ DMD board in CFTBL: DMD Works fine.

So bad board, right?

I took out the fuses in the bad board and tested for continuity and they both seem to be working.

So I am fine with buying a new board-- there is a Rotten dog one, I see, unless anyone has any better advice.

Best,

Lance

Thanks very much, everyone. I ended up getting a Rotten Dog version of the board and all is working fine now. I may someday learn how to repair the old board but didn't feel like it was gonna be too soon.
