Yes but can you post pictures of the boards and the fault? Does the menu work? Some tv's have a blue background which you can disable haha.

The blue background is not the one you can disable menu does not work just get a plain bluish screen and there is no viable fault on any of the boards
I did get a part picture when I first got the tv but I had vertical lines on the screen so checked the LED connecting flat cables and lost everything so I got a new TCon board and still nothing I did have sound before but not now I have tried with a DVD connected with HDMI cable still dead

Try running the T-con with just one ribbon cable connected at a time. Do you get a partial picture?

since you where only at T-CON playing, there are of sure when you took the ripon cable you had now broken line or shortet betwenn 2 line, in this case you have this fault and the register of the LCD has bein delete ( empty at main memory of it. took out the t_CON totaly from main board, you should have sound when you play HDMI No 1 with ACR
