HI Guys, my run of awesome luck is continuing, playing my last functioning game tonight and 15 mins in the dmd display just faded away and has not returned, before that it was perfect nice and bright with nothing missing, I looked up and saw columns of pixels fading and now nothing, do I need a new dmd or is this symptomatic of a driver board failure?
Thanks again for all your help and consideration.

Try the easy stuff first,Any blown fuses?Try reseating the ribbon cable going from the Dot matrix board to the display.What game are we talking about?

Hi pinmike,
it's a bally whodunnit?
will try and look at the backbox tomorrow, have missplaced the key and will need to get a security bit from work to open it up, just wondering if this is a common fault with dmd?

Thanks

Yes, It could be a number of things that can go wrong with DMDS.

Hi guys, looked at the boards tonight and it looks like the only visual damage I can see is to r12 and r13 resistors on the display controller, so does anyone think that the resistor blowing would cause the display to fade and die?
Thanks
