    Samsung UA55KU6500 where is panel calibration stored?

    Hi,

    Have a storm damaged TV that had a short on the power to IC207 a tiny surface mount near the emmc that still remains after I removed the IC207.

    So I got a new mainboard from aliexpress and it all works but I'm wondering if there's a way to transfer calibration data from the old board to the new one or if that's even necessary?
    I presume there is some sort of calibration done at the factory??

    There are 2 winbond flash ics w25q40cl, w25q80dv and another eeprom 24c512cl.

    I tried swapping those to the new board but the TV wouldn't boot. The new board does have a different tuner though.

    Does anyone know where the panel calibration data is stored?

    Thanks.

      What is the distortion on the screen with the new motherboard?
      And what is the part number of the motherboard?

          I'm confused. It all works, so what are you trying to achieve?
          I assume no responsibility for any stupid suggestions I might post.

              Most likely the new motherboard was for a different panel.

                  If there was some factory calibration for white balance/colour I was hoping to bring it onto the new board. The set appears to work fine now.

                      You can do calibration by yourself if that really matters.
                      Find test images, google "monitor test" or similar.
                      Check black and white levels, also gradient.
                      If you see any tint, then you can proceed with calibration, otherwise use just basic settings.
                      See if you can find 10-point option in the menu. Put gradient image, then tweak the settings a little bit to remove any tint across the image.
                      All other settings are pretty straightforward. I am normally turning off all noise reductions and reduce sharpness almost to the minimum

                          Thanks.

                          I'm suspecting there must be different software in the emmc that didn't agree with what was in the old flash roms.

                              SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
                              by triplefour
                              TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

                              tcon is built into mainboard.
                              Only one cable goes to panel boards.
                              there is a cable from one panel board to the other that links them.
                              cost cutting measure that results in us having harder time to diagnose.
                              removing the link to the second panel board allows TV to stay on with stable backlight but no image.
                              used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

                              Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]
                              by NWArkGuy
                              Well, I will be the first to admit that I screwed up...

                              In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

                              I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

                              I have 2 that I have found and have in my possession. ...

                              Samsung UN50TU8000 - Dead Panel Forensic Questions
                              by KYBOSH
                              I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).





                              When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
                              When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.






                              Later I checked for shorts on the panel PCB boards but could not find anything.
                              When I took a look with the FLIR i noticed the 2 resistors...

                              Samsung GU50TU8079U bad panel diagnosis
                              by Ierwin
                              Hello,

                              I was given this Samsung GU50TU8079U that would power cycle after a couple seconds, sometimes a few minutes. The screen would turned cloudy dark with the backlight still lit and then the sytem would restart.
                              Its one of the newer screwless Samsung models that I read a lot about panel failures here. It does not have a sperate T-CON board, just one ribon from the mainboard to the panel board and a U-shaped ribbon cable connecting the other half.
                              I went through the usual diagnostics:
                              unplugged the mainboard -> tv stayed on
                              removed the U-Shape robbon ->...
