Quoted from JBK:I'm going to go through the DMD controller board to check the previous work. My JP has a new rottendog MPU & PPB and a new Xpin power supply board. The only original boards are the DMD driver, sound board and flipper board. What are the dip switch configuration on the DMD controller.
Still have the original boards?
Watch as the game boots up. Normally you would see it before the display version that you show in your picture, if I recall correctly.
Quoted from newmanoconnor:I did, Everything is normal. I can't figure it out.
What game is this?
Quoted from newmanoconnor:I've tried new ribbon cables, and new ROM and new Controller board. Same issue.
If is the DMD in your Jurassic Park, try the DMD in Getaway.
Quoted from newmanoconnor:Fuse F7 on the supply(.5a SB) was blown.
that is for the high voltage, which the ColorDMD does not use.
Quoted from newmanoconnor:Whenever I hookup the 7pin connector with the high voltage to the power supply,the far left pop bumper flashes continuously and it ejects two balls, everytime.
Are you doing this with power on? If so, that is not a good idea.
Post a picture of everything in the backbox and the back of the speaker panel.
Quoted from Daditude:Im having the same exact issue.
Does anyone have suggestions? Has anyone fixed this issue?
Best to start your own repair thread. Measure the voltages at the DMD and post those results
