Startup State Errors
During the power-on sequence, the Motor Driver Board goes through 18 discrete operations,
as indicated in
5.7.1 Motor Drive Board Startup
in the field service guide. If an error
occurs, the following message(s) will be displayed:
“
System startup state ##
” where ## indicates the startup state number.
The startup state numbers are as follows:
0
1
Motor board - reset failed
1
1
Get ROM ID - mismatch of revision levels
2

There will also be a suggested error recovery action to be taken by the operator. They are as
follows:
All codes marked with
1
above will have the following message - "Please cycle power to
restart"
All codes marked with
2
above will have the following message - "Please replace
projection lamp and restart"
All codes marked with
3
above will have the following message - "Please dim room lights
and press Retry"
Please note that an error code can be caused by a number of different things. For example,
if there is a problem during the verification of the wedges, code 16, this could be caused by
excessive room illumination, dirt on one of the wedges, dirt on the light detector, a broken
glass wedge or defective electronics. All of the causes are indistinguishable from a software
standpoint and the error message "Please dim the room lights and press Retry" is based on
the expected cause of the error.
Note
Additional errors may occur at the same time as the startup state errors, and are
logged in the System log. Print out the System Log to check for additional errors.
