    Samsung ue55ru7400 black screen

    first of all sorry for my english but I'm translating with Google translator.

    I have a problem with a Samsung TV, the TV turns on late​,the smart TV logo appears (sometimes upside down) and then the screen remains black,the backlight remains on,the standby button on the tv works.
    Do you have any idea about the cause

    Sounds like main board/ software issue if the logo is sometimes upside down, but a lot of times when the tv is in but no picture the panel is shorted as well.

    I would first try to update the TV via usb to see if that helps.

    if no luck please post clear pics tv boards

          I tried disconnecting the two flats of the panel one at a time but nothing changed.

            History, is this your tv or did you get it from somewhere else, meaning do you know if anyone has had the cover off before.
