What to Check If Your Video Projector Is Blinking or Flickering?
Is your projector flashing like a strobe light? It can be incredibly frustrating when you're trying to enjoy a movie or photos. There are several reasons why your projector might be blinking or flickering. This guide will help you identify which component is causing the issue and how to fix it.
POTENTIAL CAUSES OF THIS FAULT:
-
Electrical power supply problem
-
Lamp or bulb not properly installed
-
Faulty lamp or bulb
-
Malfunctioning electronic card
WARNING
Before carrying out any work on your appliance,
make sure you properly disconnect it from the mains electricity supply.
There is a risk of an electric shock.
Problem with the power supply
If your video projector is blinking, it might be due to an electrical problem. Before looking at the device itself, take the time to check its power source. The electrical connection may be simply unstable or fluctuating. Try unplugging the cord and plugging it into another functional outlet to eliminate this possibility. Similarly, connecting another device to the usual power supply of the video projector will validate or rule out this cause of blinking. Additionally, visually inspect the power cable for any damage. If it is damaged, your device is at risk of blinking due to the instability of the electrical flow.

The lamp or bulb is not screwed in properly
If a bulb is not screwed in properly or a lamp is not positioned correctly in its frame, it may cause your video projector to flicker or make crackling sounds. After allowing your equipment to cool down, check that the bulb is properly inserted and try it again.
The bulb or lamp is defective
One of the most common reasons for a flickering video projector is a worn-out bulb. The projection lamp or bulb typically starts to flicker when it nears the end of its lifespan (between 2000 and 5000 hours depending on the model). Replacing the bulb with a new one will likely eliminate the observed phenomenon.
A lamp may flicker when it has reached the end of its life cycle. It will then enter a relatively stable period before gradually declining.
However, be careful as a lamp that has not been properly cooled (due to power outages or storms) can suffer irreversible damage.

Malfunctioning electronic card
If you've replaced the lamp but the issue of the screen blinking persists during a projection, then it may be due to a faulty electronic card. Unfortunately, if this is the case, your only option is to replace the card. This scenario is less common than a lamp at the end of its lifespan, but it can unfortunately occur, leaving you with no other choice but to replace it.
