It may be an issue if the images are not clearly shown from the projector, the most probable causes for this issue are the controls not working properly, or the lens is dirty or broken. To update it, check the controls to see if the screen changes, and if it does not, check the lens. You are most likely going to replace/clean the lens.

While working, the projector randomly gets warmer or shuts off without notification

Projectors may overheat due to a struggling/damaged fan. To fix this, remove any pieces or materials blocking the fan or stuck in the fan. If there is nothing blocking/stuck in the fan, you may have to replace it.

Your projector may have something in the vent, air filter, or fan that can cause the projector to overheat. To fix this, use an air duster to remove the dust from the filter/vent/fan.

The menu buttons will not respond or appear on the screen

When the buttons are not affecting the projector, there may be something inside it that is blocking the connection. You will have to open it to get to the motherboard. Then remove the pieces blocking the connection

Sometimes the wires can disconnect from the projector. To fix this, you should open the projector and check the wires to see if they are disconnected. If they are disconnected, place them back to their original placement. The placement will most likely be on the motherboard.

The screen of the projector does not show anything, and you know the projector is turned on

This can happen sometimes, the image you are trying to show will not be shown on the screen. The lens cap is the probable issue. First, check if the lens cap is removed, if it is not removed, take the cap off the lens.

There could be some cables that are damaged or do not function. To update it, replace the input cable

The settings on the projector may be set differently than you want them. Ensure the settings are proper using the remote or buttons. Double check the socket, the input, and the device it is plugged into. If the issue persists, go to settings and make them what you want them to be.

The projector does not respond or show any sign of turning on

If power is the problem, then there should be no visible lights, sound, or image from the projector. Ensure that power cables are properly connected to the projector and outlet. Double check if you are pressing the correct button to turn on the projector as well. If the issue persists, try a different outlet to plug the projector into. If there is still no power replace the power cable and try again.

If the issue does not stem from the plug or the electrical socket then the issue is with the projector itself, specifically the power supply. Check if the power supply is connected within the projector and, if it is, then turn the projector on to see if it works.
