Cindy, can you elaborate on this "color started given out"? Do they look faded or just very dark image altogether?

Dark image all together

Sounds like your backlight is going out but it is hard to tell without actually seeing it. any chance you can post some images of what you see.? Adding images to an existing question A dark picture can be caused by a bad Z-sus board If you can post some images of all of your boards. For that you will have to take the back off.

Sorry about the delay, we moved and got really busy. I have added the pictures you asked.

Please let me know if you need anything else

Cindy, thank you for the pictures. Yes as previously suggested this could be caused by the Z-sus Board. I attached an image of where to check and what to check for. You will need a multimeter for that.

The board itself is available at places like this. If you are handy with a soldering iron, you can also try and replace the transistors on the board itself. Those are FGPF4633 IGBT's and are available at Mouser.com or you can buy a repair kit from here.
