Title: Help With A Bally Alpha Pending Status LMVSB
Post by: erbs on February 11, 2021, 06:22:39 PM

Machine is a Bally Alpha Sapphire Sky with Progressive. Sold it 5 years ago. Machine had been working fine shut down and stored for over a year. Changed both batteries. One on the Mpu other on the backplane. Got most of the settings done then got the Pending status error LMVSB. The mpu switches have been bypassed. Any help would be appreciated.

Well I checked everything I could. I'm thinking the MPU may have gone bad. Will try that next.

Changed the MPU today. Same error. Anyone have any other ideas on what to check next?

backplane. Your "common" ground line might be broken somewhere.

I haven't got back to that machine yet. They are suppose to drop the machine off next month. I am going to replace the backplane. From what I had read that should be the problem.

I finally got back to this machine. The problem was the backplane. Rickhunter was right.

FYI, I just had the same problem last night on a machine. I found the wiring goes to the 6 pin molex connector on the back plane labeled “MAIN DOOR, COIN TRAY, DROP DOOR” It sits in the middle of the board 1/3 the way up from the bottom. After toning out wires, I took a jumper wire and connected it on the bottom left pin and bottom center pin ( Red wire, off white/Yellow stripe ). Machine message disappeared and fired up. I later went back and had to Re-solder the board for that connection, back to normal. I guess when I pushed the jumper wire in it flexed the bad solder joints enough to work. NOTE: if you do this You must leave the molex connector plugged in, because of the other 2 wires control a circuit as well.
