Moreover, in some projectors there is an indicator light which blinks when the projector battery is low but in old projector this light is not present so the low battery is not indicated. And also sometimes even this indicator light is fault and does not indicate the low battery. The solutions of this weak or low battery problem are mentioned below:

Replacement of the Battery:

Placement of Projector:

The placement of projector in a place where the temperature is regularly maintained is very important to prevent its overheating issue. So, the place where the projector is mounted or placed must have any air conditioner or fan to cool the projector down while working.

Dust Cleaning:

The aggregation of dust in the projector fan can slow it down or even stop it. So, the projector must be placed in a location where dust is least present and its fan must be regularly cleaned for proper functioning.
