    Try this one, but the problem may also be in the 25Q80 firmware, which is responsible for the panel and t-con settings. Are the motherboard and panel part of the original kit?
    denedim değişen bir şey olmadı.. emmc den yapabilir mi ? veya t-con regülatöründen? t-con devresi çalışmıyor her hangi kısa devre yok.. t-con voltajları çıkmıyor.

      How are you 100% sure that you have a working panel?
      Have you checked the hdmi and usb ports on the signal lines for low or short circuit?

        usb ve hdmı portlarında kısa devre yok.. panel sağlam eminim.. başka bir kart takarak görüntü alabiliyorum.. 25Q80 i diğer karttan kopyalıyorum.. değişmiyor durum aynı. ilk defa böyle bir arıza geliyor başıma.. ayrıca usb de 5volt okuyorum

          Connect the control points (put a jumper) on FB_TRDY_1 and FB_TRDY_3 and pulling out one lvds cable at a time, see if the image is on whichever side.

              Yes, it's better to replace the motherboard so as not to waste time, the problem could be in both the processor and emmc....

                evet emmc denemedim olabilir.. işlemci de olabilir ihtimaller denizi artık ilgin için teşekkür ederim değiştirmek en mantıklısı olacak.
