First code is coming from my broken tv (made in china) (TV starts but it doesn't show any image - backlit ON - black image) - reset with EXIT pressed for 13 sec works but image is still black (i tested it in blind, by knowin the steps and responses of tv).
The second board is from a same model 40D5500 (made in czech republik) but 3 moths newer and the main board is revision B while the broken one has revision A (BN41-01660A).
I have the posiblity to test the boards but i m afraid not to burn the working ones by combining them with mines.
But in your case i doubt you need T-CON board. I think your mainboard is broken, not T-CON. How did you realize about T-CON issue?
Then i have measured the input voltages on the data cable and i see around 1,2-1,3 V so my conclusion is that the T-Con board is receiving data.
After this i measures the output on the test points before LCD cables and there i get 0,2-0,3 V - meaning no Video Signal in my opinion.
Anyway, im not sure about this testing precision (found on the internet) and i wanted to eliminate by replacing the t-con with a compatible one and i got to my first question.
Part of t-con:
