Closed problem report
Description
-Flippers active when in attract mode
- Stuck solenoids always active. Upper drop target 1 & 2, buzzer & multiball kick out, lower left & right drops targets, shooterlane launch kick out, upper left kick out, and both magna saves all stuck on. Fuse for these solenoids blows, no surprise.
Current diagnosis-
-Issue goes away if 40 pin connecter is unplugged between driver board and MPU.
-Corresponding PIA #5 on driver has the outputs for these solenoids stuck HIGH. Unclear if PIA is receiving bad data, or is faulty.
Media
No media.

Installed driver board, after a reboot machine when into attract mode, board diagnostic checks out fine, and solenoids no longer are stuck on.

- Used ChipQuik, to remove old PIA chip, soldered in a new 40 pin socket, checked for shorts, and then installed new PIA chip. Need to reinstall the board to check if this was causing the issue.
Log Entry
Ordered new PIA from pinball life, PBL-600-0443-00, that replaces the legacy 40 pin IC 6821 PIA.
