Benq Projector Press Power Button Again to

Recognized brand in the manufacture of video projectors, BenQ satisfies both professionals and individuals with quality products. However, like all electronic devices, these are non foolproof. Information technology then happens that it encounters malfunctions such as not turning on any more. Simply do not panic ! There are solutions to try to repair information technology cheaply or at best at no cost. So observe out today what to do when your BenQ projector does non turn on?

Easy treatment when your BenQ projector does non turn on anymore

To begin with, there are some easy checks and operations that tin can restart your BenQ projector. Check them out below.

Reset your BenQ projector

First of all, brand sure that your remote control is not defective and that this is non the crusade of the problem.

If aught helps and your BenQ projector does not turn on after checking, this confirms that the fault is with the device. Information technology may be that small malfunctions processor or software related is the crusade. To solve this trouble, you will need electrically reset your BenQ projector by proceeding as follows:

• Unplug all cables from your projector
• Press the On / Off button for 10 seconds
• Wait 1 hour
• Reconnect the projector power cablevision

If the procedure worked, your BenQ projector should plough on once again. You tin then reconnect all the cables. Otherwise, another problem is involved. Then continue with the troubleshooting steps.

Projector maintenance trouble

When your Benq video projector no longer turns on, sometimes it happens considering of a apparatus maintenance problem. Indeed, a video projector is a relatively fragile electronic device that requires some attention.

The device has ventilation filters for prevent dust and dirt from getting inside. But despite that, over time they manage to penetrate and tin can pose problems for the proper functioning of the projector. In addition, they can block the air vents. If you lot have never cleaned the appliance and find that it is dusty, then you will need to cleaned up. Be conscientious, be delicate when cleaning and apply suitable cleaning products (spray without water and without static electricity or dry cloth). If in doubt, check the cleaning tips provided in the user manual your BenQ projector model.

If your projector has suffered shock, drop, or oxidation, it is also very probable that the device is subjected to internal damage. In the result of a fall or impact, the lamp will be the element most likely to take broken down. In the event of oxidation, electronic and electrical components are the most at risk.

Power trouble

As shortly as an electronic device is no longer powered, it volition no longer give any sign of life. When your Benq video projector does not turn on overnight and that his lights are off or flashing, so it may mean that he knows a problem in its feeding process. Here are the checks to exist carried out:

1. Make certain the connections are functional. Bank check that the cables are firmly seated in their respective ports and that the cables are non damaged. In other words, that they are non plain-featured, damaged, burned, melted, or stripped.
2. Make sure the wall outlet is working. To do this, plug some other functional device into the socket. If it turns on again, the outlet is not the source of the problem. If it does not come back on, the outlet is defective and you lot volition demand to accept it repaired by an electrician.
3. In case you are using a BenQ portable video projector, check that information technology is sufficiently loaded to be able to start.

Overheating problem on a Benq projector

when BenQ projector does non plow on anymore ou that information technology turns on and and so turns off, information technology is also possible that a overheated be the crusade.

Indeed, the device automatically detects when its temperature when stopped or when operating is as well high. The temperature sensor then causes the video projector to cease automatically. Several phenomena can exist at the origin:

• The ventilation hole is blocked. Cheque that the ventilation tin be washed correctly past leaving at least 50cm of distance from whatever object.
• The external surroundings is unfavorable to its proper functioning. Get out the BenQ projector in a ventilated identify, in the shade, away from moisture, and in a place where the temperature does not exceed 40 ° C.
• A faulty temperature sensor. Indispensable to operate, when it is down, the BenQ video projector will not be able to turn on.
• A fan problem. If information technology can no longer dissipate rut due to a fan error, the internal temperature will exist too loftier and it will then switch off automatically during operation. Information technology will then be necessary to expect for information technology to absurd down and then that it can restart. Still, it will plough off once more subsequently a few minutes of utilise.

Also exist aware that a component problem, and more especially the lamp, can cause overheating simply as well other issues that could be responsible for the failure of your BenQ projector. Cheque them out below.

Technical manipulations when your BenQ projector stops working

When your BenQ projector does not turn on anymore, it is very likely that a component trouble or the origin. It will then be necessary to replace the defective part. It takes some electronic skills to avoid dissentious your device.

Component trouble

When a component breaks down, the repercussion is immediate and several malfunctions tin can occur subsequently. In near cases your BenQ projector does not work at all. The components most at take chances are the lamp, the motherboard, and the power supply lath.

Lamp trouble

La lamp is the nigh frail part of the projector and which wears out the fastest. When it breaks down, as a issue and instantly your BenQ projector will no longer plow on.

Indeed, the lamp has a limited lifespan and it will therefore take to exist replaced sooner or later when it breaks downward. In that location are two types of lamps with more than or less long lifetimes. Mercury lamps have a lifespan of between 2000 and 6000 hours while LED lamps have a lifespan of upwardly to over twenty hours.

In any example, when the BenQ projector lamp fails, information technology could be due to several things:

• the lamp connector is not properly connected or has burned out
• the bulb has burned out
• the lamp is reaching the cease of its life
• the lamp overheats and causes the device to switch off automatically

Depending on the origin of the error, you will then need either simply change the bulbEither alter the unabridged lamp (frame + bulb). Knowing of course that the latter solution is often much more expensive.

Remark : If you accept already changed the lamp, the usage counter lamp may not take been reset and it is probable that this is the cause of the fault. Indeed, when you lot exceed a certain number of hours of use of the projector, the counter may prevent the device from turning on equally a safety measure.

Power board problem

When your BenQ projector does not turn on, the failure can besides come from a faulty component present on the power supply board. Indeed, to function, many components interact and are essential in the circuit. Optocoupler, capacitor, fuse, transformer etc. are then just as many cardinal electronic components merely which end upward draining and no longer functioning.

When your projector no longer turns on because of a component, y'all will accept to disassemble the entire device to access the power board.
