    Hello,

    I own a Jackbot pinball machine. When I bought it used, all was working fine. Over time the dot matrix score board would work on power up for less than a minute and the black out. It is now to the point of not working at all. Another side issue that needs fixed after the screen is that it is the french language. Im hoping there is a way to reset the system since I dont speak french.

    I have no experience in electronics aside from taking them apart "haha" I did check the connections from the screen to the circuit board and looks good. I'm not sure if fuses play any part in the screen but none of them looked burned out.

    I'd appreciate any help. It's hard to find anyone in my area to come and diagnose the problem...

    I'm glad there is a place online to get help though. I'm thankful there is a community out there that love pinball as much as I.

    Check the pins on the DMD the big connector goes to for broken or cold solder joints. Then check voltages to the pins on that connector, see if any are low or missing.

    Set your CPU to English.
