    Ok, I will go ahead and disassemble everything. Let's see what I'll find! I'll let you know. Thank you!

      So I got the cables and the t-con board from China. It came early. I was excited. But somehow nothing changed. What does that mean now?

          I tried the cables first on my t-con board. Same as with the one from China. BTW: I bought this t-con board: https://de.aliexpress.com/item/1005006203664939.html
          I didn't know but it doesn't look new to be honest...

          And the new cables are a bit wider but the pins are both 80 on each side. I took two pics. Can you have a look?

              Well, from the photo you can see that the step does not coincide with the original, there is a shift...

                Yes, that's what I thought. Then I aligned them as Diah said and it looks close. (Pic1)
                But the length of the pins is definitely different. The originals are longer. (Pic2) Is that a problem?

                  The thickness of the contact pad corresponds to the original. There are no traces left from the clamping of the connector, as if there is no contact..

                    ah, that's because it was an unused one. I got 10 instead of 4 from China! Here I just de-attached one of the new used one. There you see the marks:

                        I have, I have.
                        Since then the TV is like that. It also smelled a bit. I told about this when it happened a couple weeks ago. Remember? But I bought the cables and the t-con board AFTER that. Since then I didn't do any cable detaching while the TV was plugged in. Lesson learned....

                              This is more likely a reflection from the flash.

                                  there are another way to know why the gamma dead and where the issue.... using the original T-CON and the replacement one we need to do it in points turn on and check the screen
                                  A- with Original T-con in place all 4 ribbon cable connect to panel
                                  1- disconnect only left side U ribbon cable after test if no change put it back
                                  2- disconnect only right side U ribbon cable after test if no change put it back

                                  B. disconnect 2 ribbon from left side after test if no change put it back

                                  C- disconnect 2 ribbon from right side after test if no change put it back

                                  do all points again with replacement T-con

                                        Yes, luckily it's just a reflection! I took another pic.

                                          Thank you for the detailed description. I will do this now but before I need to know something: what and where is the U ribbon cable??
