    [ILCE-7R] Sony Alpha 7R Display no backlight

    Hi Everyone!, hope you are doing well.

    I am experiencing an issue with my A7 R, the main display is not working anymore. In the specific the display backlight is not working, the image is displayed but the screen is so dark.

    I tried to replace the display(LCD901) and the flex cable(LC-1014), I also checked the fuses on the board and they are not interrupted, but the malfunction is stil there.

    Could you help me? Thanks a lot
