There’s nothing worse than a broken projector ruining movie night. If it won’t turn on or you’ve experienced diminished image quality, you need to know how to repair a projector. Even the best projectors run into issues from time to time, so read on to learn how to fix the most common problems.


  • Check the power cord and input device connections if your projector isn’t showing an image.
  • If your projector overheats, make sure its air vents are free from clutter and dust.
  • See your product’s manual for the most accurate reading of status lights.

How to Fix Common Projector Issues

Most projector fixes are simple and require just a bit of time. For example, if you know how to repair a projector screen, you will be more than equipped to troubleshoot a projector.

No Power

If your projector isn’t turning on, make sure it isn’t on standby mode. In addition, check your power cord and make sure it’s fully plugged into a working power outlet. Lastly, if you’re trying to power on your projector using a remote, make sure the batteries have a charge. Additionally, read our guide discussing how do you hook up a projector, so you know you’ve got it connected correctly. If none of these solutions work, you may have a broken unit that needs repair.

Projector Image Is Discolored

If your great cheap projector’s image quality and color accuracy are suffering, always check your VGA cable and input connection. Next, do input testing to ensure your projector receives a signal. Lastly, adjust the color settings for your display, to fix the color on your projector.

If none of these simple fixes work, you may need a lamp replacement, color wheel calibration, or color wheel repair. In addition, look into how to fix a retractable projector to make sure the screen itself isn’t the cause of the color issue.

Insider Tip

Try to contact your manufacturer if your projector is still covered under warranty. A repair shop is quicker, but a warranty exchange is cheaper.

Overheating Projector

Projectors naturally get hot due to their powerful lamps. As a result, they can overheat if they have dust clogging the projector vents. So, check your projector latches and temperature lights to make sure the device hasn’t overheated. Then, make sure there isn’t any clutter that might block your projector’s air circulation.

Projector Light Is Blinking

If you see blinking lights on your projector, that doesn’t always signal an issue. Always check your broken unit’s project manual for the most accurate projector light readings, but below are some common meanings.

Power Light

If your projector’s power button light is green or flashing green, it is powering on. An orange power light means it’s in standby mode or is shutting down.

Temperature Light

If your temperature light is flashing red, orange, or yellow, your projector is likely overheating. A simple cleaning of the unit and its surroundings should clear it up.

Lamp Light

If your projector’s lamp light is flashing, it may be time to replace it.

Burnt Out Projector Lamp

A dead projector lamp light is one of the most common projector issues, but this issue has warning signs. If your picture seems dull or dark, and images start to look washed out, your lamplight is going out. If you turn your projector on but see no image, it’s likely already burnt out.

This is a complicated repair, so it is usually best to shop for projector repair services or contact your projector manufacturer’s customer service. A repair shop will have a quicker turnaround time than a warranty repair, but a warranty repair is free.


Never open or operate on your projector while it is plugged in.


How can I maximize the lifespan of my projector?

To keep your projector working longer, you should make sure your projector has enough airflow. In addition to keeping the projector cool, make sure to keep it in a dust-free environment and do a semi-annual basic cleaning and calibration.

Is my projector worth servicing?

If your budget projector breaks down and you’ve owned it for a few years, it may not be worth repairing. That said, if you have a premium long-throw projector with high lumens, the projector repair cost might be worth it. Either way, get some repair estimates and shop around for the best projector repair service.

When should I replace my lamp?

The average projector lamp will last about 5 to 10 years, so you may never have to replace it in the projector’s service life.
