Quoted from Sonic:
Been reading the issues as of late and will simply attach this link from another thread....https://pinside.com/pinball/forum/topic/dmdmk64-new-dmd-multicolor-by-pinballsp-is-on-the-way/page/10#post-3980443
Maybe you should also mention that this product has the last row display uncorrectly which is really a simple problem and has´t been fixed for weeks now. Not to mention that it does not provide even the simplest way of colorization like scene based palette switching.
Quoted from crunchysue:
So ... now that I've got my PIN2DMD-XL installed, Frank has an intermittent issue where the DMD stops at its second screen, which is shown below. I can start and play a whole game, and the display just stays stuck here. It was happening intermittently, and now it happens every time. Any ideas what this problem could be? I've tried reseating all the connectors, and I've made triple sure that all the ribbon cables have their red stripes on pin #1.
That is really strange. It seems to be missing a signal line. Try to play with the ribbon cable and the connectors when the game is on to see if it comes to live then. We first need to find out wether it is a display or a sega controller issue. Do you have the chance to put it into another sega machine for testing ? We could also test with another dmd. It does´t need to be a large display. 128x32 also works. I used a stern LED DMD for testing when I repaired my Sega dmd controller. Trying another ribbon cable or turning it 180 degrees on both sides could also help.
I´m sure Rappelbox will take care about your problems.
