Causes and solutions of automatic shutdown after projector is turned on

The automatic shutdown of the projector after starting can be investigated according to the following common reasons.

There is too much dust.

The interior of the projector is not cleaned regularly, resulting in too much dust in the projector, the dust-proof filter screen is blocked by dust, and the high temperature in the projector cannot be ventilated and cooled normally, and the temperature control group of the machine automatically alarms and shuts down. Cleaning the filter can remove the dust from the machine, thus solving the problem.

No signal input

The projector will automatically shut down after no signal is input for more than the set time, so just cancel the automatic shutdown setting.

Bulb problem

Problems with projection bulbs (mostly caused by improper user operation, such as continuous switch, long switch, etc.). ) can only be solved by replacing a new light bulb.

High voltage drive board problem

The projector's high-voltage drive board (also called lamp power supply) will automatically shut down if it breaks down, so you need to contact after-sales maintenance.

Motherboard overheat protector

The motherboard overheat protector will automatically turn off after aging. If the above reasons are still unresolved after investigation, please contact after-sales maintenance.
