Hi Folks
Barcrest MPU4 Club vegas. Has been running fine, now prior to boot I get MPU4 Mux selects alarm.
I know this relates to a short on the lamp selects (blue plug)
There are various sub circuits and a lamp extender board on this machine.
By a process of elimination, If I unplug the top blue plug on the board shown on the picture, the machine boots.
This connector feeds the top glass feature lamps.
Could a blown bulb cause a short? otherwise what else?
Thanks
Phil.
