Step 1

Determine if the blinking screen is part of the projector's normal function by observing when it happens and if it stops after a short period of time. If, for example, the screen blinks a few times after the mode has been changed and then the blinking stops, this could be normal for your projector. Consult with your projector's manual if you are uncertain.

Step 2

Check the video connections on both the projector and the device to which it is connected, such as a laptop or tablet. If the video cable is loose, the screen may flicker and blink due to an incomplete connection, which causes a broken video feed. Press each end of the video cable firmly into their respective ports to ensure that the connections are solid.

Step 3

Connect a new video cable to the projector if the problem continues; the current video cable may be damaged with a broken wire or missing pin. If the problem stops after testing a new video cable, discard the old cable.

Step 4

Connect the projector to a different input device, such as a different computer. The graphics card in the device to which the projector is currently connected may be faulty or insufficient for properly displaying the video feed.

Thanks
