    When turned on, cold vertical stripes appear that obscure the image content, disappear after about 5 minutes. Chilling T-con and motherboards correctly operating TV does not evoke malfunction. Probably something with the LTF460HJ03 matrix electronics.
    Maybe someone had a similar fault? Samsung UE46C6000: Vertical Stripes Obscuring Image at Cold Start - LTF460HJ03 Matrix Issue?

    And you will pay for this "advice"?
    Or otherwise ...
    I understand that this is a "tip" and offer to sell in one, so send this album to your colleague, and join me right away ... 2 dicons for a return shipment if you need it. ;)

    Did not you teach your spelling?

    When the rear panel was removed, the TV reacted to twisting the casing.
    Loosening the screws from the motherboard, the problem resolved. I will do reballing bga systems.

    Hello, I do not understand why a colleague wanders to determine where the fault may be, in the matrix, T-con or maybe the motherboard, you can not determine whether the stripes appear during OSD / MENU only or not and do not narrow down with the reduction of image proportions as well whether they appear immediately after turning on the TV-then you could come to some conclusions without measurements even.

    Search area narrowed to the main board. BGA overdraft does not work, the graphics chip / scaler is damaged. To confirm the theory another damaged plate from the series "6"
    Typical product aging effect, after warranty and on TV.
