    Default Hisense fix

    Hi all.
    My son was given a Hisense smart TV with the fault of having vertical bars on the screen.



    He followed this video and got it working.....

    Sorry.....I just realized I post the wrong video. Dunno how I did that.



    Just wondering why this works to fix it.

    Do you want to summarise what they do to fix it? Sitting through seven minutes plus of Youtube video isn’t my idea of fun.

    Summary : He puts a tiny piece of tape on a few of the Tcon ribbon contacts.

    That is a bit of a weird one. My first thought was that the connector had become weak and he was increasing the pressure on the contacts by packing the back of the ribbon cable… but he is actually using the tape to insulate some of the conductors.

    I had a read of some of the comments.., from those it seems like the display panel is faulty - the fault drags down other parts of the display, making the TV unusable.

    By insulating a few lines, he seems to be isolating the faulty row or column of pixels in the display panel, so there is only one very narrow dead row of pixels instead of big / wide bands of them.

    That's why I put this on here. Cos it doesn't make sense.
    When my son told me about it I thought the same as you, to increase the pressure on the contacts by packing the back of the cable.
    When he followed the video he ended up with a perfect picture, no lines at all.

    according to the vid - there is a dead track of pixels (or pixel) and when the tv addresses the faulty pixel - it gets a feedback and causes a confused signal causing a flicker. Through process of elimination by covering a zone of tracks, it stops addressing the broken pixels and hence no more flickering.
