buffalo mav500 bv door open??
« on: August 20, 2018, 05:43:35 AM »
Maybe someone has an idea because i am stumped.


on friday i installed led panels behind the belly and top glass, when i turned the game back on, i had a bill door open lockup.


 tried unplugging the leds, no change
tried manually depressing the switch, no change
tried jumping the switch connection, no change
swapped out I/O boards, no change
reseated all connections on the backplane, no change


might this error be something stuck in memory and keychipping might clear? 


any ideas to try would be great.

Did you try pulling and reinstalling the mpu and I/O boards?

The I/o was swapped out. Haven't tried resetting the mpu yet, will try that in about an hour when I am at the machine again

Reseating the mpu didn't change the status.  Gonna try a ram clear a little later

i'm a dummy  :banghead: .


when i put the LED panel in the belly door the new bracket did not have a spot for the cherry switch to push against to get a closed door signal(why a belly door is related to a BV door i'll never know)

Glad you got it figured out.
