  • HDMI Cable Not Working. This is a very common problem and is caused by a bad connection. To resolve this problem, plug out the HDMI cable from the TV and projector and then plug it back to both devices. After trying several times or luckily the first time, it will start working.

If this plug-out and plug-in solution does not work, try checking the connection from both sides and see if the cable plug is damaged or not. In most cases, the problem is with the cable while people think that there is a problem with the projector or TV.
