Self-Tests: Power-On Diagnostic Tests
Power-On Diagnostic Tests
Upon power-up, the 120 Series Monitor’s Main Motherboard and DSP Board
perform a number of tests before allowing the monitor to enter the normal
operational mode. After setting the
Power switch to the on (I) position, the tests run
for approximately two seconds. If all tests pass, the monitor enters the normal
operational mode. If a test fails, you will see one of the following error messages
centered in the display:
SYSTEM FAULT: ROM
SYSTEM FAULT: RAM
SYSTEM FAULT: DSP
The first two errors indicate a problem on the Main Motherboard. The last error
indicates an error on the DSP Board. If the monitor displays any of these messages,
turn off the monitor and contact your Corometrics Service Representative.
