Are you having trouble getting your BenQ projector to turn on? Don’t worry; you’re not alone; many users have encountered this issue, and it can be caused by various factors. 

In this article, we’ll discuss why your BenQ projector is not turning on and 10 easy fixes that may help get your BenQ projector working again. 

Let’s get started!

How to Fix BenQ Projector that isn’t Turning On 

1. Bad Wired Connection 

Bad wired connections can be one of the main reasons why a BenQ projector may not be turning on. A loose connection between the power source and the projector typically causes this issue. 

A loose wired connection prevents the electricity from being properly supplied to your projector and turning it on. 

So, it would be best to inspect the power cable to ensure it is securely connected to the power socket and projector. 

If the issue persists, you should try using another cable to ensure that a faulty cable or a lost wired connection does not cause it. 

2. Check the Power Source 

When troubleshooting a BenQ projector that is not turning on, it is important to first check the power source. 

Ensure that the power cord is securely plugged into an active electrical outlet and that it is properly connected to the back of the projector. 

If all connections appear secure, unplug the projector and plug it back in again before attempting to turn it back on. 

Also, check for any blown fuses or tripped circuit breakers in the outlet or power strip and reset as needed.

3. Replace Faulty Cord 

A faulty or blown power cord of your projector can be the cause for this problem, and you can fix it by inspecting or replacing the cord. 

First, unplug the current power cord from your projector and wall outlet, and then check for any physical damage or signs of wear. 

If you notice any fraying, cuts, kinks, or other signs of wear and tear, it’s time to get a new power cord.

It’s essential to make sure to get a replacement cord that’s compatible with your BenQ projector model. You can consult your user manual for more information about compatibility requirements.

4. Restart your Projector 

Restarting your projector is an easy way to troubleshoot any issues you may be having. It will help you to remove the projector’s software bugs and help it to work correctly. 

First, ensure the projector is plugged into a power source and the power switch on the back of the projector is in the “On” position. 

Next, press and hold the “Power” button on your remote control for 5-10 seconds. This will turn off, and then restart your BenQ projector

If this does not work, unplug the power cord from the back of your projector and give it 30 seconds before plugging it back in and repeating this process. 

5. Clogged Air Filter 

A clogged air filter could be one of the most common causes for this issue with your projector not turning on. 

Dust, dirt, and other debris may accumulate in the air filter over time and, if left unchecked, can lead to overheating and even cause power failure. 

So, in order to prevent this problem, you should regularly check the air filter and replace it with a compatible one. 

The signs of a bad or uncleaned air filter are increased fan noise or an increase in the system temperature of your device. 

 If the fan noise is louder than usual, then it’s possible the air filter is blocked due to an accumulation of dust particles within the projector’s ventilation system. 

Also, if the system temperature has become higher than normal, this could also indicate that the air filter is blocked or needs to be replaced.

6. Overheating 

Sometimes overheating can lead your device to this problem. If the projector is left on for a prolonged period of time, it can become too hot and cause the projector to malfunction. 

Overheating is also a common problem if the projector is placed in an environment that is not adequately ventilated or has poor air circulation. 

Improperly setting up the device in relation to the wall or other objects can also increase heat buildup, so it’s important to ensure that a good amount of space is allocated around your projector for proper airflow. 

Moreover, you should check for any filters or vents regularly for dust buildup can help reduce the chances of overheating.

7. Lamp Problems 

You can also run into problems due to a malfunctioning projector lamp. This type of issue can be caused by a number of things, such as an incorrectly installed lamp, an incorrect voltage setting, or a defective or damaged lamp. 

It is important to take the time to diagnose and troubleshoot the issue before replacing the projector lamp.

When checking for issues related to the projector lamp, start by double-checking that you have installed it correctly. 

If everything looks good, then check for any signs of physical damage on the outside of the housing or on the inside of your projector near where you installed the new lamp. 

If you find any damage, this could be preventing your BenQ projector from powering up normally. So, you should solve it to fix your projector. 

You can also check the voltage settings on your projector to ensure they are correct. As several projectors come with various voltage settings, which need to be set according to the type of wattage and size of the bulb being used. 

Incorrectly adjusting these settings can cause problems with the power supply and potentially prevent your projector from turning on at all.

8. Faulty Motherboard 

Faulty motherboards can be a common cause for your projector not to turn on. The motherboard is the main circuit board inside the projector. 

If the motherboard is faulty, it won’t provide the power required for the projector to function properly. 

Signs of a faulty motherboard can include an inability to start up or random reboots without warning. Supplementary, there may be sound issues such as no audio being outputted or distorted audio. 

Faulty motherboards often need to be replaced with new ones in order to restore functionality to the BenQ projector.

9. Malfunctioning Remote 

Malfunctioning remote controls are a common problem with your BenQ devices. This can be caused by a variety of issues, including dead batteries, a faulty connection between the remote and projector, or incorrect programming. 

If your projector is not turning on when you press the power button on your remote, it could indicate that there is something wrong with the remote itself. 

Ensure your batteries are fresh and properly installed in the remote. Further, check if any other devices nearby use the same frequency as your projector’s remote. If so, try to reprogram your remote to avoid interference.

10. Contact Customer Service 

If you are still having trouble with your BenQ projector not turning on, it is best to contact customer service for assistance. Customer service can provide information and troubleshooting tips that may help diagnose the issue. 

They can also direct you to repair centers or authorized BenQ service personnel who can further assist in resolving the issue.
