Did some looking around, and the problem may be being caused by your Main board.

Thanks for the reply. I saw a very vague troubleshooting chart pointing to the main board as the faulty video/picture. It does look like the HDMI inputs are attached to the main board. All older Sony Bravia’s say the TCON is responsible for a faulty picture. I can’t tell if this 2014 model is equipped with a TCON board.
Replaced the main board today to find the same issue as before

Teerev that is why it is important to post images of your TV. That way we can see what you see and we can always help with the identification of boards , parts etc. Remove the back of your set and take some pictures of the layout as well as the different boards. Use this guide https://www.ifixit.com/Guide/Adding+imag... that. It will allow us to see what you see. Then start by using a Triage method, determine which could be primary cause and which could be secondary. Something like this
after that proceed with a general approach to the troubleshooting of No Video like this
The rest will then depend on your findings. BTW your set has a T-con board and I do believe it is actually behind your BAXL board (for now my money is on a bad T-con board ;-)

I have the same problem. Replaced both the main and tus boards...no change. Just ordered a new ldhm board. Hoping that will be the fix.
