Soaybe the entire t con board needs to be replaced.

When you removed one of the cables did you have a source connected to the set ? You should get half an image, not just a light screen. Unfortunately, getting half an image during this test usually means the screen is bad.

I'll double check. So on one cable, or the other, I should see half? I did try the menu, buttons on remote, etc. And saw nothing.

On mine (granted mine was a 2012 vintage set) it only had one T-con board and that was all I had to replace in mine to get it running.

I cannot get a single pic, half screen or otherwise on this. No sound either. Not sure what to do at this point

Try connecting an oscillator to the A/V inputs.
Here's a link to some helpful troubleshooting tips:

That link used to be available as a downloadable pdf file but I guess it got removed.

I don't have an oscillator. Is it possible screen is bad or should I order the replacement board and take a chance?
