      Sorry, no. If a boot loot should be a mainboard in the theory, but, I've proven myself that not always. Try to disconnect backlight error pin on the backlight PCB if firmware upgrade won't work.
      Not always a customer is right. 😉

    Maybe the screen has lines anyway? I have seen them before (AUO) panels are rubbish, you can send the board away to get the chip replaced and will come back with no Netflix and another app, they will no longer work I think it’s about £100+ roughly

      Thank you, but, I'd rather do a Frankenstein out of it if can find VGH, VGL, AVDD & VDD signals for this particular display ;). Can be a Panasonic or Samsung after, I don't care :D.
