I found some interesting infos here https://www.flippermarkt.de/community/forum/threads/dmd-display-funktioniert-nicht-mehr.120990/. Mike3h said« Using a 1N4004 at D10 on a -00 power supply will allow way too much voltage through and run the small DMD display much too bright. This was done on displays that are outgassed, to use them beyond their normal life, delaying the cost of replacing the display. »
Maybe your D10 is a wrong model?
More infos here at « 4.5.7.3 Missing -110V or -98V for DMD Display Power »
