Suddenly when I try to change picture settings under "Preference" for the HDMI inputs... several of the options are grayed out. Such as Dynalight and Dynamic Contrast. I have tried several things and nothing has helped... even did a factory reset. The strange thing is they work on the ANT input.

Hi rduncan27,
I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction.
Lets do a simple test to check the functionality.
Let me know your findings and we can proceed from there.

Use the menu button in the front screen of your tv.Maybe your remote control need a battery.

You either have failed 24vdc power supply section or failed backlight inverter board, check for 24vdc first, look for caps with leaking/bulging top.
