A projector runs, then shuts off and reports that the lamp has reached its service-hour limit. The air filter is clean. Which part should be replaced?
Select an answer to reveal the explanation.
Short Explanation
The projector is telling you the lamp has used up its hours, and the filter is not the thing clogged. You replace the lamp. The input selection, a ghosted image, and a printer heater are not that hour counter.
Full Explanation
A lamp-hour limit is the projector's own end-of-life notice for the lamp. The filter is clean, so airflow is not the shutdown cause in this stem. Replacing the lamp is the maintenance the message names. The video input is already showing an image before the shutdown. An hour limit is not a wrong-input message. Burn-in is a ghost in a panel. It is not a lamp-hour counter. A fuser belongs to a laser printer. It is not the projector's lamp. Exam caveat: let the lamp cool, and do not touch the glass of the new lamp with bare fingers. Oil from skin shortens the new lamp. Operational check: install the lamp, reset the hour counter the way the manual describes, and confirm the projector stays on. Reset the lamp-hour counter after the new lamp is in, once the lamp has cooled. Do not touch the new lamp's glass with bare fingers.
