    Excellent video but I have no idea why this tv works ok after doing the cutting job because if you cut the drive clock signals there is no gate driving on TFTs in the screen? So can you explain please

    • @tevzTVTevatronics
      @tevzTVTevatronics  3 роки тому +9

      Hello zibi ski! I think the gate from left to right is in parallel if 1 of the gate has a defect or short circuit the high get voltage automatic shutdown. so if the sorted gate is bypass or disconnects the high get voltage will operate normally. The signal gate signal in the left supplying goes to the right, so sometimes it results in the image being darker than the other side. That is my understanding of this issue. I hope you understand my English. Thanks.

    • @zbyszekskibinski
      @zbyszekskibinski 3 роки тому +4

      @@tevzTVTevatronics yes I think I understand so the clock signals in one half of the screen are connected ( in parallel) with the ones in the other half. This connection is established in the glass matrix if I got you right or it runs on the edge of the LCD panel to be precise. So if we cut bad gate on signals the good ones from the other half get through to the horizontal COF anyway. Do you know where the short is exactly, I wonder if its in the horizontal (line-up) COF or somewhere in the corner of the panel thanks for your reply and explanation!!

    I have seen your video very attentively. 1 thing will always supprise me how do you where to cut on the Coff. It doesn't written either.
    I have 1 led tv 55inch myros. I sent it to repair. But they said it can't be repaired because the screen is gone.
    The problem was half screen horizontal lines and another half sometimes displays is coming and gone for some second.
    I open the TV I seen the cut both side of the Coff. And 1 they have resoldering it.
    And the other 1 they let it.
    Still I want to know why they cut and left it.
    And said to me can't be repaired.
