How to maintain the projector?3 points to use the projector for 5 years longer

When we finally get the beloved projector, we treat it cherish, but once over a period of time, we may not have the patience, which may cause the loss of the projector and shorten its life. So, how to maintain the projector for a longer service life? In fact, it is very simple. It is good to pay attention to the following three points:

How to maintain the projector?3 points to use the projector for 5 years longer

1. Do not switch on and off frequently

Reason: Because frequent switching in a short time is easy to cause the loss of the projection lamp, please keep the switch on and off correctly, so as to make the projection lamp use time maximize. No sudden or premature damage.
Suggestion: Shut down after powering on or powering on again after powering off. There is a period of time in between. The interval should be at least 10 minutes. If possible, it should be controlled for more than half an hour.


2. Do not use it under unstable or low voltage.

Cause: The unstable voltage of the projector can easily cause the voltage comparator and voltage doubler rectifier circuit inside the machine to cause erroneous operation, causing the output voltage to rise or fall suddenly. Burn down the motherboard and power supply.
Suggestion: When the mains fluctuates above 30V, the projector power should be cut off.
How to judge the voltage is unstable?
You can observe the indoor lamp. If the fluorescent lamp flickers or fails to start, it means that the voltage is very unstable.

3. Dust removal and maintenan on a regular basis:

Generally speaking, our dust removal is mainly based on lens cleaning, filter cleaning and air intake.
1. Clean the lens:
Reason: the lens of the projector is more prone to dust, and sometimes the accumulation of dust may affect the projection effect.
Therefore, if dust is stuck on the lens, it can be wiped with lens paper or cotton balls. Do not wipe the lens with a wet cloth or other things. This is to avoid scratching the lens and affecting the future projection effect.

2. Air inlet dust filter:
Reason: The core components of the projector are very sensitive to temperature, too high temperature will cause damage; if the air inlet of the projector is blocked, the internal air flow is not smooth, causing the interior of the machine to be too high, the temperature sensing system will Prompt the machine to protect and shut down automatically; then it is likely that the air inlet is blocked by dust, so we also need to clean the air inlet regularly.

If there is a filter, the filter sponge can be removed and washed with water, and then it can be used after being thoroughly dried with an electric hair dryer. For the air inlet without filtering sponge, you can use a fine brush to sweep the dust.

The ventilating air duct design of Dangbei Projector's straight in and out has minimized the ingress of dust, especially the F1C comes with one-key dust cleaning function, which can be used as a double guarantee. After opening, the projection will emit a loud running sound The dust removal work is completed when it is over.
