Probleme avec DMD display

Post by Vectakk »

Bonjour,

je me suis procuré une pinball Data East avec DMD dernierement,

je l'ai joué et testé avant de partir avec, tout allait bien.

Arrivé chez moi ( on a été précautionneux durant tout le transport ),
je l'ai rebranché, fais quelques games avec, encore tout sous controle.

Mai p-etre 1 heure plus tard,
le display a soudainement arreté de fonctionner,
plus rien n'affichait...

J'ai ouvert le cab a la grandeur ainsi que ouvert le top ou sont les boards,
checkez toute les connections qui partent du display aux différents boards ( fils, ribbons ),
tout retiré et rebranché pour etre sur que tout est connecté serré,
et rien encore sur le display.
Pourtant, la game joue tres bien ( lumiere, son, etc... ) !

Des idées et/ou suggestions pour me sortir de ce pétrin ?

PS: Je suis débutant depuis à peine 1 an dans le magnifique monde du pinball.
Je reste a Québec. Si ya du monde du coin qui peuvent venir jeter un coup d'oeil ou me référer un réparateur, ce serait le bienvenu.

Merci d'avance !

Vérifie le fusible du haut-voltage/display en premier.
Sois-sûr que les cables ribbons sont biens branchés.

Bonne chance!

Based on your signature, I'm assuming the game is Star Wars.
As Sylvain mentioned, reseating ribbon and power cables to the dot matrix controller would be the first thing I do.
Do you know how to use a digital multimeter? If so, check that you are getting correct voltages at the dot matrix board. I took a screen capture of page 45 of the manual. Refer to these voltages. If they are off, you will at least having a starting point.
I know on WPC games, for the two negative voltages, they must be 12 volts apart. Based on these schematics, I would assume the same for this game.

Like others have said, make sure to re-seat all connectors BOTH at the DMD and on the boards.

Also, with the power off, check the connectors on the power board. Many Data Easts get seem to get cold solder joints on those boards. Wiggle the largest connector on the board (with wider pins), jiggle it a bit and then turn the machine on. If you get your dmd back, that might be the problem.

Nice taste in machines! I started with a BK2K and SWDE too.
