    Toshiba 65X9863DB (Vestel) - Panel Lock

    I'm working on this TV which was stuck on a flashing green/red light with no picture. Everything seemed to point to a motherboard issue, so I changed that out with a new motherboard.

    The TV worked perfectly well for 30mins to 1hr at which point the picture went again.

    UART dump shows these two lines:

    [IsOLEDPanelLocked] : gPanelLocked = 0x3 !!!
    [read_dbtable]OLED PANEL LOCK, not to init panel .!! !!!

    UART dump from when the TV was working was:

    [IsOLEDPanelLocked] : gPanelLocked = 0xFF !!!

    Anyone experienced with mboot knows what is going on, why this lock got set and how it can get unset?

    Thanks.

      Vestel Firmware - Toshiba 32W133DN
      by anlu
      Hello, i have an old Toshiba 32W1333DN (sorry, misspelled the headline) TV that had the standby led green/red flashing and no lightup problem, i repaired it by measure the led output as suspect led problem, i measured the LED:s one by one and found one bad led, i replaced the the led-straps and the TV works.

      Now i need to update the software because the new rc "RM-L890" does not work and i think maybe it could be an firmware issue?, i have struggled to find it without any success because all of the links where invalid, i contacted Toshiba but they do not support this model...
