    How to fix Hisense 43A6H 4k Google TV - 10 Blinks?

    Hi I replaced the mainboard, the t-con, and wifi, still no dice.
    Any idea on what it could be, causing the tv to not turn on? Just blinking LED light.

    Processor gets hot so I know the Mediatek MT9612 is functional.

    Thanks

    Does backlights come on when you hit power?

    If not take a flashlight to the screen after hitting power and look for image.

      Sounds like the TV version of an RROD. Unfortunately, you will have a replace one or more components, most likely.

        Non stop blinking led on Hisense usually means no Internet connection. So probably not rrod. Still should check if backlights are working

          Test the Backlights with a Backlight Tester. Most likely the Backlights are defective.
