Sorry to say that most HDMI issues are that of the scource and not the TV. You can check with Mitsubishi to verify that you have the latest version of software for your TV, but that is no guarantee that it will fix anything. If you have tried other devices on the HDMI port without any issues then you definatley point out that the cable box is at fault. Maybe the cable company should swap out the box..

Your TV needs the modified temp sensor installed by Mits authorized service center. It's covered under extended warranty for 3 years after date of purchase. Repair takes about 20 minutes and not too expensive if you're out of warranty period. Part #299P313010A
