How should the projector be maintained daily?
[Office Partner Information Center] The projector is a kind of precision electronic product. It integrates mechanical, liquid crystal or DMD, electronic circuit technology, so it is more delicate in the process of use.
Many friends have used the projector for a period of time and will find a series of problems such as lower and lower brightness and unclear image display. This is because everyone did not pay attention to how to maintain the projector in daily use.
So share with you the six common sense of projector maintenance, so that everyone can better maintain their favorite projector!
Must regularly filter the dust
Dust removal is an indispensable maintenance work for projectors and is especially important for LCD projectors.
Because the projector LCD panel is fully cooled, there is a special fan that air-cools it at a flow rate of several tens of liters of air per minute. After the high-speed airflow passes through the filter dust net, it may entrain tiny dust particles, which rub against each other to generate static electricity. In the system, this will have an effect on the projected picture.
Therefore, it is very important to prevent dust in the environment in which the projector is used. It is strictly forbidden to smoke because the soot particles are more easily absorbed in the optical system.
Avoid strong impact, crushing and vibration
Strong earthquakes can cause the displacement of the liquid crystal film, affecting the convergence of the three LCDs during the projection, and the phenomenon that the RGB colors do not coincide, and the lens and the mirror in the optical system may also be deformed or damaged, affecting the image projection effect, and the zoom lens Under impact, the track will be damaged, causing the lens to become stuck and even the lens to be broken.
Try not to use the projector for a long time
Because after all, the effect of air cooling is limited, which is why the bulb has a life span. That is to say, the fan is not enough to take away all the heat, and the accumulation of heat for a long time will cause the brightness of the bulb to drop. Therefore, it is recommended that users do not use the projector for more than 4 consecutive hours.
Most need to be cleaned - projector lens
The lens is one of the most important optical instruments in the projector and the most vulnerable part of the projector, so be careful when cleaning the lens. Whether the projector lens is clean or not will directly affect the clarity of the content on the projection screen. When encountering various circles or spots on the screen, most of them are the dust of the projection lens.
At this point, you should use professional lens paper or other professional cleaners to remove dust from the projector lens. In a dusty environment, the projector should be used frequently and the projector lens should be cleaned regularly.
The lens cover should not block the projection light for too long.
We may take a break during the use of the projector, but we don't want to turn off the projector. If the projector is always on for a while, it will feel awkward, so it will often be blocked by the lens cover, but The point of attention is not to use the lens cover for a long time, so that the heat of the projected light will be blocked at the lens. If it is too long, it will inevitably cause high temperature damage to the lens and the optical machine.
Switching frequency can not be too high
Many electronic components have a "breakdown" hazard in the switching action, which is why we try to avoid frequent switching when using the computer. The same light bulb is more delicate, especially for projectors that support quick start-up. Instantly use a larger current to achieve a shorter warm-up time and increase the risk factor by one step.
Therefore, when using the projector, do not turn the machine on and off frequently to avoid frequent current or voltage surges on the projection lamp and circuit.
To sum up the above six points, the common sense is that the projector needs to be dustproof and shockproof for daily maintenance. There is also a very important point: moisture protection.
Because the projector is very vulnerable to the impact of humid air in the projection environment. According to a document, under normal circumstances, the air humidity of the projector is working between 45% and 60%. If the air humidity is higher or lower than this range, the projector will not work. In a stable situation, damage to the machine can be very serious.
