SEIDEL VERSION –ST TROUBLESHOOTING
& DIAGNOSTICS SECTION
Troubleshooting Strategy
Use common sense and a systematic method of troubleshooting to determine the exact
problem, probable cause and remedy. Use the process of elimination to find the faulty
component. Always check for the simple and obvious causes first such as unplugged,
loose or broken wires and bad sensors, bent, pinched, stuck or jammed components.
READ - IMPORTANT:
If the problem cannot be resolved using the steps in the following
chart, it could be caused by a faulty main board, or the software associated with that
board. The problem may be isolated by installing a board, and/or sound and software
chips, from another game to see if the problem persists. Ensure that the software chip is
from an identical game or additional problems may result. See the Service and Repair
Section.
