Our cable box has been reset several times. When we hit the INpu options, The TV port works but now the HDMI ports are not active. I have tried all four ports and have tried a different HDMI cable. All have been working fine for the past year. We pay for HD and are not able to access. Cannot get any live person on a phone!!
Maybe you should check your TV"s documentation , reset it to factory defaults , then run the intitial setup once more?
Thanks for your response! I was looking into your solution but today the TV clicked, the picture just dissappeared and the TV went off on its own. When turned back on there is no picture. Sounds like some repair or replacement is needed. Appreicate your trying to help.
