    If you have changed all of these components the problem has to be with display. You should also check ribbon cable if there's something wrong with it. Well if it's dead or damaged you should give up and get new display or buy new TV.

    Bonjour BenToul

    Did you resolve your problem? I have exactly the same issue with a Techwood TK5014

    Thank you

    Dark screen? No or no backlight? The diode flashes and does not turn on? Write in detail.
