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

    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

    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.
