I absolutely HATE DE pins and Rottendog boards!!! It seems to me that every time I have that combination, there's gonna be trouble. Latest episode:
Finished up a DE Star War. Really nice, full LED's, excellent condition. I noticed that the original DMD took about 10 seconds to come on when the game was first turned on, but it was rock solid after the initial 10 seconds. Had the game for at least 6 months and played it regularly throughout that time with no problems.
Delivered it to a guy's house and the display would not come on at all. WTF?? Checked for loose connections, checked voltages, etc. Only thing I saw was the Rottendog power supply was putting out -150v for both the -100 and -110v test points. Reseated ribbon connectors as well as all ps connectors. At one point got a partial display with lots of background garbage, but that went out and then nothing again.
Took it back home, put a new DMD in it and still nothing. Borrowed a DMD av board and Rottendog ps from a friend and started out by putting in the new Rottendog ps. Game gave out an instant loud hum, several solenoids pulled in, and I turned off the game quickly. I did measure the voltages though before turning it off and the -100 and -110 were right on.
Put in the original Rottendog ps that was in the game and now no hum but the MPU isn't powering up. No controlled lighting or game music. Tried the new DMD av board and it displayed the garbage screen for a second and then nothing. At this point, I have no idea what happened, but I know one thing - I HATE DE games with Rottendog boards in them!! Anyone with any idea what happened?
