BIG PICTURES! I think there may be three.
Ron:
For reference, your post and my post look the right size on my 48" TV/Monitor. Hiz look too wide. I had to sit down and catch my breath on the way to his reply button.

Ok I removed the pictures because they are of no consequence now. The screen no longer comes on, I get 5 fast flashes and 2 slower flashes on the little arrow light at the bottom of the TV.

I read the same thing regarding the error code, I ordered a main video board and power supply board to hopefully resolve the issue

I have replaced the main board (where all the HDMI connections are) and the power board. I tested to make sure I have 5V DC coming out of the power board and receiving 5V DC into the main board. I am still getting 2 slow flashes and 5 fast. Any suggestions?
Incoming power appears to be steady 120V

FYI the screen doesn't power on unless I press the power button which will interrupt the 2 slow 5 fast and turn the light solid for about 30 seconds, sometimes the screen will flash on for just a second. I have a hard time replicating this, it almost seems like a short because of the intermittent behavior.
I have done a continuity test between all the wires on all boards. I could not do a continuity test on the solid silver ribbon cable that runs in between the main board and the T-Con DUNTKF975WE14 board.

Another update:
I believe it is the small T-CON board now. I realized if I unplugged the right side ribbon cable that the screen lit up and the left side displayed a normal picture. I swapped the ribbon cables from left to right and the problem remained the same leading me to believe the problem is in the board and not the cables. I have ordered the board and will update once I replace it
