Viewsonic Projector Keeps Shutting Off: Causes and Solutions

It can be a real buzzkill when your projector gets in the way of your movie marathon. Your viewing party might be cut short, but don’t worry; it’s fixable.

Most projectors inadvertently shut off due to wiring issues. If your Viewsonic projector  keeps shutting down, here are some things you might want to look into.

Viewsonic Projectors: Causes for Unexpected Shutdown 

Below, we list some of the main problems for unexpected shutdowns in Viewsonic projectors. 

While it is often an issue with your hardware, we will include some of the most common software issues. As the adage goes, “knowing is half the battle.” 

You should discern what issues may be the root cause before sending it to a repair shop or aimlessly tinkering with it. 

Here are some of the most common causes behind power issues: 


Check to see if your unit is hot to the touch.

If you can’t keep your finger on it for more than a few seconds or there is tangible waste heat surrounding the unit, your Viewsonic projector  might be overheating.

Overheating is not an encompassing issue. Instead, it is a cocktail of causes that may lead to a domino effect that can permanently damage your projector’s internal and external components. 

Sometimes, the environment is the cause and the only thing that stands between you and a seamless movie marathon. The room temperature might be too hot, which adds to the heat your projector’s processors are already producing.

The surface might also not be breathable. Some projectors cannot sit atop solid surfaces that absorb heat without dissipating it properly. 

Appliances and electronics produce heat from their internal processors. The surface must appropriately dissipate the heat to prevent it from being sucked back in by the electronics. 

Uncertified Alterations

An unreliable aftermarket lamp may not make a seamless integration to your projector. As a result, it may not manage heat the same way its certified counterparts do. 

All minor and major components built-in to the Viewsonic projector are put together with precise calculations to work in conjunction. If you replace any of its parts, you risk internal digital miscommunications. 


If, before you connected your projector to anything or played a movie, you left the room for a while only to come back to your projector shut down, don’t worry. 

This instance happens when your projector has built-in power-saving functions. Without activity after a certain period, typically five to fifteen minutes, your projector will enter standby mode before shutting down completely.

Factory Hardware Issues

If your projector is new and you’re sure you paid your latest energy bills, and there are no other issues with your electricity, you may find the problem is with the projector’s hardware. 

Power Cord

While unlikely, check for snags and tears on your projector’s power cord. There may be abrasions or rips that expose the cord’s wiring.

Its exposure might bear faulty wiring issues, which lead to power problems. Safety features will prevent potential combustion by cutting off electricity running through faulty wires. Sometimes that means the prevention of turning on. 

However, it may also mean allowing only enough power to turn the unit on but not enough to keep it on, which leads to your unit cycling off. 


Viewsonic’s portable projectors have built-in Lithium-Ion batteries. While Lithium batteries are some of the most dependable, it isn’t immune to defects.

It is improbable that it has any leaks, fried systems, or built-up moisture, but if your unit has an underlying battery issue, you need it checked out immediately. These issues may arise from its improper packaging and handling during its delivery. 

It may corrupt the rest of your hardware if not addressed and replaced immediately. 

While these are all undue hassles for the projector’s users, there are things you can do about it.

Sending your unit to the repair shop is ultimately the best option. However, you should know what issues you are sending it in for as its owner.

If you send it in for a diagnosis, make sure the technician you entrust it to is reliable. Some jump at the chance to charge you unnecessary fees for problems your projector doesn’t have.

It is best for you to sus out the issues you can and send your projector to them first. If you look like you know what you are talking about, technicians are less likely to ding you around for more cash. 

Alternatively, you can deal with the minor issues at home. Still, we don’t suggest you deal with them yourself when it comes to wiring. 

It is inadvisable to tinker around wires, especially if you don’t know what you’re doing. 

To prevent causing permanent damage to your projector and sustaining personal injuries, stick to diagnosing your projector’s issues and sending it to professionals for any technical repairs. 

When My Viewsonic Projector Overheats

Most devices come with a sort of stand which allows some breathing space between the bottom of the unit and the surface, like the Viewsonic M1 Portable Projector . The breathing room underneath permits the proper distribution of heat, preventing your device from reabsorbing too much heat. 

If it is already overheating, turn it off, or if it’s turned off automatically, don’t turn it back on

Before turning it back on, take it off the current surface and move it into a surface that isn't heat-absorbent

Ensure the room temperature isn’t too hot. If it’s too hot, you should have something with cooling effects to counter the heat. Turn on fans, air conditioners, or gadgets that provide your projection with direct cooling 

It would be best to give it enough time to cool off before switching it back on to prevent it from cycling off again.

When the Uncertified Alterations I Made Negatively Affect My Viewsonic Projector

All of the projector’s components are pieced together methodically. Whenever we make changes, it alters the entire system, not just one part. 

It’s never a good idea to integrate parts you aren’t sure of into your projector. If you still have the original parts, it would be best to shift them back to their original state

If you switch out older parts for newer ones, you can contact the manufacturer and check if it is defective. 

It should go without saying, but we’ll remind you that you should only buy parts from verified sellers. Even when sellers assure you that it won’t make a difference, original parts and substitutes can make an impact. Don’t compromise your entire projector to save a few bucks on parts. 

Original parts also come with a warranty that comes in handy during these times.

When My Viewsonic Projector Shuts Down Due to Inactivity

All Viewsonic projectors come with a default Power Save mode. It helps save energy and prolong your unit’s battery life if it has a battery.

It isn’t hard to figure out that all you need to do is turn it back on when you’re about to use it when it enters standby mode. 

However, if you prefer it to stay on even after leaving it untouched for a while, check your user manual on how you can modify your system’s power-saving functions. 

The process might look something like this:

  • Launch the ‘Main Menu’
  • Click the ‘Power Management’
  • Scroll to the ‘Smart Energy’ section
  • Search for the ‘Power Saving’ option on the sub-menu
  • Toggle the setting ‘On/Off’ according to your preference

When My Viewsonic Projector Shuts Down Due to Hardware Issues

Hardware defects are always tricky. It isn’t best for you to open and tinker about for a diagnosis. 

When you get it right out of the box when these issues arise, you can send it back to the shop for a replacement. Ensure you purchase one from a certified dealer that includes a warranty with every purchase. 

Before plugging it in to see if it’s working, examine the equipment. 

Check for any visible signs of damage. Examine the wires closely for abrasions and the actual unit for dents and holes. 

Send it back immediately if you notice anything besides a Viewsonic projector in pristine condition. 

Final Words

As you can see, it’s normal for anyone to go through issues with their projectors. 

However, there are things you can do about them. You can check your unit for issues and send them back on warranty when you’re dissatisfied with the one you got. 

Warranties are crucial in all purchases and are only accessible through certified distributors.

Besides warranties, purchasing units from certified sellers guarantee your gadget’s authenticity. It also means you can send it to reliable technicians for any repairs. It would be best if you didn’t buy from uncertified dealers to prevent getting stuck with faulty equipment.

You are less likely to encounter problems that you can’t quickly remedy with guaranteed original products. 

You can easily manage any further issues you might deal with using authentic products at home.
