A technician is called to a classroom to troubleshoot a projector that occasionally turns off. The technician reproduces the issue and notices the projector will not turn back on until several minutes have passed. After 15 minutes of being turned on, the projector turns off again. Which of the following should the technician do next to resolve the issue?

Adjusting the standby timeout would not address the underlying issue of overheating. While this adjustment may change the time before the projector goes into standby mode, it does not prevent the projector from shutting off due to excessive heat. Therefore, this action may not effectively resolve the problem.

Checking the power cable connection is important for general troubleshooting, but it is unlikely to be the cause of the projector shutting off after 15 minutes. If the power connection were faulty, the projector would likely not turn on at all or would shut off immediately, rather than after a specific duration.

Replacing the bulb may be necessary if it is faulty, but it is not the most immediate solution to the problem described. The projector's shutdown behavior suggests an overheating issue related to airflow rather than a bulb failure. Therefore, replacing the bulb might not resolve the projector's shutdown issue.
