the side with blinking error have short... show us the panel buffer boards of this side, also you will have on this side U ribbon cable at the middle of boards disconnect it and see if you get 3/4 Image on screen

I have dissconnected it in the middle. I have second 1/4 of screen withe. Here are photos.

my questions if you see image on the reset of the screen.... or you can hear sound... this is more important that the white you are talking on

[domix]

No i dont have sound and no image. I have backlight and 1/2 screen is withe, i i sepparater UCable modules i have only 1/4 screen withe color and 3/4 screen is only backlight. Where is supposed to be image is only bright withe.

Should i replace which board?

[domix]

Anyone?

I get new t-con board. I replace it, and when turn the tv on it turn on only backlight whitout 5 times blinking red.

so the problem is almost the same just like wiht orginal t-con board.
i didnt get any android sound. If i disconnect u cable from t-con to buffer board. I only get half of screen white color and nothing other on screen.

any other solution to check?
thanks

Your panel is bad, it's shorted. You can try "tape fix" eventually, find it on youtube.

start by masking on the right contact of the T-con to the screen just 4 pins at the time from left to right or on the U ribbon on buffer board same way if not ok just go on and search even by pin

I taped al 10 CLK pins, image is like as it should be. Every thing works

should inleave it so? Or i will need to find if only one or two pins is making problems? It will be okey if i leave it masked all 10 clk pins?

then just leave it that way if you are satisfied some pics does not hurt

[domix]

Okey. I will leave it that way. Image is okey.
thanks
