How to Reset Lamp Timer On a BenQ Projector?

BenQ projectors have a lamp that works as a great light source for digital projection functions. The lamp lets the image get seen clearly on the screen. This lamp, therefore, has a timer. The lamp can work for a given duration before it wears out and needs changing. The timer alerts the user how long the bulb has before its useful life is over.

There are two ways of resetting BenQ projector lamp timers. One uses the reset button on the projector’s control panel, and the other initiates an automatic reset. The manual method works for BenQ projectors with a reset switch, while the automated process is for models without a reset switch. However, you can use the automatic form even if the projector has a reset switch.
