Error Codes If the status code display on the back of the projector shows one of the following values,
you have encountered a likely system error requiring the attention of a qualified service
technician. Acknowledge and clear the error by pressing EXIT twice on the rear-panel
keypad. Try resetting the projector by powering it off, allowing it to cool and powering it on
again. Refer to
Table 5-2 and contact your dealer if the problem persists.
The specific code number identifies the source of the error detected, and is particularly
useful in cases where the projector is far away. For example, the code “27” means the
lamp could not be turned on.
