ViewSonic projectors come with three types of LED light indicators: Power, Lamp, and Temperature. Now, these lights behave differently depending on the state of the projector when it’s turned on. But generally, when you see red lights, it’s a sign that something’s up.
In this post, we’ll cover the possible causes of red lights on ViewSonic projectors and how you can solve them.
What Causes Red Lights on Viewsonic Projectors?
If you see red lights on your ViewSonic projector, one of the following could be the cause:
Overheating is an issue that affects all brands of projectors, not just ViewSonic. In ViewSonic projectors, you’ll often see the temperature indicator turning red if that is the problem that’s ailing them.
And if the internal sensors detect extreme temperatures, the projector will automatically shut down as a measure to protect its components.
If that happens, the best course of action is to allow it up to 20 minutes to cool down before attempting to turn it back on. Otherwise, it will keep shutting down by itself and you won’t be able to project anything.

Clogged fans and filters
Clogged fans and filters are another cause of red light in ViewSonic projectors. When dust accumulates on the fans and filters over time, it hinders the flow of air through the projector which in turn causes heat to build up inside.
As you would expect, the temperature sensors will detect an overheating problem and the temperature indicator lights will turn red.
The solution to clogged fans and filters is to develop a cleaning routine, especially if you reside in a dusty area. Get yourself a good quality air duster that will help you blow out any accumulated dust in no time.

The lamp timer has not been reset
A lamp timer is a useful tool that tells you when the lamp is nearing the end of its lifespan. When it turns red, it means that you need to replace the lamp. The problem though is that sometimes it continues to show a red color even after changing the lamp for a new one.
You probably forgot to reset the timer when you were done with the replacement. The projector thinks it’s the same lamp and you need to reset the timer so that it shows the lamp hours of the new one.
To do that, go to ‘Menu’ using the remote. Select the Lamp Timer and reset it to the correct hours.
Insecure lamp and open lamp cover
If there is an insecure lamp or the lamp cover is open, you’ll see a flashing red light on the lamp indicator.
To fix it, remove the lamp and securely put it into position and close the cover.
If the lamp or any other component such as a ballast board is faulty, you’ll see a red light on the indicators.
In this case, it’s best to consult a technician to help you sort out the issue. But if you’re sure the problem is a faulty bulb, you can always replace it yourself by following the instructions provided in the manual.
Be sure to purchase a lamp that matches your ViewSonic projector and pay attention to the safety guidelines in the manual as you do the installation.

If you’re one to move around with your projector, chances are that you may accidentally detach a connector wire. That could also happen as you do regular maintenance or lamp replacement triggering an alarm in the form of indicator lights.
It helps to inspect as many connector wires as possible after doing any meaningful work on your ViewSonic projector.
Charging or software download
If your ViewSonic projector is charging or downloading software and you see a red light on the power indicator, that is normal. Some models are made that way and you should not worry about it.
That red light should however turn off after the download is complete or when you disconnect the projector from the power outlet.
The indicator lights on ViewSonic projectors are handy when you suspect there’s an issue with them. However, these lights can be confusing, especially when they show a red color. In this article, we’ve covered the most common causes of red lights on ViewSonic projectors and their solutions. But there’s no guarantee that any of them will work on your projector.
If none of the solutions we’ve provided works, your best bet is to get in touch with the technical team at ViewSonic. You will find all the details you need on their official website.
