What should be done after turning off the projector before replacing its lamp?

Wait a few minutes
Remove the lamp housing
Clean the projector surface
Test the lamp before replacement

The correct answer is: Wait a few minutes

Waiting a few minutes after turning off the projector is crucial for safety and effectiveness. When a projector is in use, it generates significant heat, particularly in the lamp housing area. After powering down, the lamp and other internal components remain hot for a certain period. Allowing the projector to cool down reduces the risk of burns or injury when handling the lamp. Additionally, this time ensures that any residual electrical charge dissipates, making the replacement procedure safer. Handling the lamp immediately after turning off the projector, without allowing it to cool, could result in burns or damage to the projector or lamp. Therefore, it is standard practice in maintenance protocols to exercise patience and ensure that the device is safely cooled before attempting to replace any parts, such as the lamp.
