Purchasing a laser projector is a wise investment, no matter what you’re using it for. They offer many different benefits and will last you a very long time. However, to get the most out of that projector, you’ll want to know its common problems and how to fix them well in advance.
Laser projectors have common problems like not turning on, blinking lights on the unit, low image quality, and no image on the screen despite turning it on. Generally, you’ll want to ensure your laser projector has no problems with its power supply and that its connection to your source is solid. Also, use high-quality source media to get the best projection possible.
Read through this guide to equip yourself with the knowledge necessary to troubleshoot your laser printer. Once you know what problems to expect and how to solve them, you’ll minimize any downtime with your projector.
How To Troubleshoot A Laser Projector?
Troubleshooting your laser projector is easy when you know what problems you’ll likely face.
Here’s a list of 4 common laser projector problems and how to fix each one:
#1 The Laser Projector Won’t Turn On
About this: The first issue you’ll likely experience with your laser projector is that it doesn’t turn on. Naturally, that can disrupt the plans involving that projector, whether giving a presentation or viewing a movie at home.
Here’s how you can be sure that your projector is indeed failing to turn on: firstly, it won’t produce any image on your screen.
On top of that, its indicator lights won’t illuminate, and you won’t hear any noises from within the unit.
How this problem happens: A laser projector that won’t turn on is experiencing a problem with its incoming power supply. The root causes of that problem are:
- Power cord problems: The power cord connecting your laser projector to the wall socket has holes, tears, or rips and is no longer working correctly.
- Faulty wall socket: The socket you plug your projector into is defective and does not provide a reliable power supply.
- Tripped circuit breakers: The circuit breaker protecting that wall socket has tripped due to a power surge or other electrical fault.
- Blown fuse: The electrical fuse protecting your laser projector has blown, preventing it from turning on.
Any of these individual issues can prevent your laser projector from turning on. So, you’ll have to troubleshoot each of them one by one.
How to correct it: The correction necessary for this issue depends on the root cause.
For instance, you can reset a tripped circuit breaker or purchase a new power cord for your laser projector.

However, you’ll need an electrician to fix a faulty wall socket and a repair technician to replace the blown fuse. You can fix these two items yourself, but only if you have the necessary expertise to do the job safely.
#2 There’s A Blinking Light On The Laser Projector
About this: Take a close look at your laser projector, and you’ll see several lights and other indicators. Each has a corresponding meaning, typically represented by words or icons printed directly underneath each light.
Some lights will remain solid (i.e. stay on) when a feature or option is enabled. However, a blinking light is typically something that requires your intervention.
How this problem happens: A blinking light means a problem with the laser projector you must attend to. Depending on the projector brand and model, the blinking light could represent only one issue or be color-coded to respond to several different problems.
For example, a blinking orange or red light could mean a problem with the laser or another internal component.
The precise meaning of a blinking light will differ between laser projector brands and models. So, you have to refer to the user manual to understand what they mean for your unit.
How to correct it: You can’t fix a blinking light on your laser projector until you know what it means.
So firstly, note which light on your laser projector is blinking. Be sure you know its label, icon, and color.
Then, shut the laser projector off while you interpret what the blinking light means. That will prevent further damage while you’re troubleshooting the issue.
Lastly, refer to the user manual to understand which problems the blinking light corresponds to and how the manufacturer requires you to fix it.
#3 Low Image Quality On Projector
About this: Laser projectors offer many benefits over their peers, like lamp- and LED-type models. One of those benefits is producing a higher image quality on the screen for better presentations and movies.
How this problem happens: Despite the advantages of laser projectors, you’ll have moments when the image quality on your screen is poor. That’s especially true when you first buy the projector and gradually learn how to use it correctly.
When the image quality is low, there are two likely causes: incorrect projector settings and low-quality source media.
In other words, your laser projector is not set correctly to provide a clear, high-definition image on your screen. For example, the projector’s focus hasn’t been set correctly.
Alternatively, the media you’re playing with the projector is low-quality at the source. So if you play a low-resolution movie from your computer, it will appear very low quality on the screen.
How to correct it: Firstly, ensure that your laser projector is set up correctly. Go through its settings and adjust its focus to suit your screen.
Secondly, ensure that your source media is of the highest quality available.
#4 Laser Projector Is On, But There’s No Image
About this: Earlier in problem #1, you saw that the projector wasn’t on. Now in #4, another common problem is that the projector is on, but it’s not producing any image.
How this problem happens: This problem also has 2 likely root causes. Firstly, the lens cap might still be on. But, don’t worry, the lens cap is very easy to overlook, and many users still forget to take it off at first.
Secondly, the projector is likely not connected to the source (e.g. your laptop) correctly. For example, the cable might be loose or disconnected entirely.
How to correct it: Firstly, check that you’ve removed the lens cap from your laser projector. Be sure to keep it near so you don’t accidentally lose it.
Secondly, inspect both ends of the cable from the source to your laser projector. Remove the connector and blow away any dust, if necessary. Then, ensure that it’s connected firmly.
Frequently Asked Questions (FAQs)
Here are some helpful troubleshooting questions and answers for laser projectors:
Do Laser Projectors Need To Be Replaced?
Yes, laser projectors will eventually need to be replaced, thanks to their limited lifespan. However, laser projectors last around 20,000 hours before their projection starts to dim.
Does A Laser Projector Need To Cool Down?
Yes, but it only takes a few moments. Laser projectors don’t run as hot as conventional lamp models do. So, there’s very little need for a warmup or cooldown period.
Can You Replace The Bulb On A Laser Projector?
No, you do not have to replace the bulb on a laser projector.
Do Laser Projectors Run Hot?
No, laser projectors do not run hot. That’s good for two reasons. Firstly, you don’t have to wait for the projector to warm up before using it. Secondly, you also won’t have to wait for it to cool down after you’re done.
Do Laser Projectors Have Fans?
Laser projectors run cool, so there’s no strong need for a fan. Most laser projector manufacturers don’t include built-in fans inside their models. As such, you won’t hear fan noises coming from a laser projector, either.
