Based on the symptoms described, the problem with the projector seems to be related to the lamp, and possibly the cooling system. The fact that the problem continues after replacing the lamp suggests that there may be an issue with the projector's cooling system, which is causing the lamp to overheat and shut down.
Therefore, the two most likely actions to address the problem are:
A. Reset the lamp life counter: This is a maintenance task that is often required after replacing a lamp. The lamp life counter keeps track of the total number of hours that the lamp has been used and alerts the user when the lamp is approaching the end of its life. Resetting the lamp life counter after replacing the lamp ensures that the projector is accurately tracking the usage of the new lamp and prevents premature shutdowns due to incorrect usage data.
B. Replace the cooling fan: If resetting the lamp life counter does not resolve the issue, the cooling system of the projector should be inspected and serviced. The cooling system is responsible for keeping the lamp and other components from overheating. If the cooling fan is not working properly or is clogged with dust or debris, it may not be able to cool the projector adequately, leading to overheating and lamp shutdowns.
In contrast, adjusting the brightness, updating the laptop video driver, installing a higher lumen lamp, or changing the video resolution are unlikely to solve the problem described. These actions may improve the overall performance or image quality of the projector, but they are not directly related to the lamp shutdown issue.
