    Hello, today I have a purple spot (glow) in one place. Can you fix it yourself?
    Is this backlight? Some dust? Is the whole matrix to be replaced?

    Unfortunately, today everything is done quickly and cheaply.
    And here they let me know about assembly errors, inaccuracies, etc. negligence in production.
    I don't think it was the backlight fault or similar electronics damage.
    They probably let themselves be known about the stresses and inaccuracies of the assembly. Rather irreparable on its own.
    If the TV is under warranty, I would fight for it. If not, I would learn to live with it.

    Not a TV set is already 3 years old, so it already came from a trusted annual loan.
    Either I'll live or sell much cheaper with such a matrix. Or maybe a slug and loosens everything a little.

    Let me connect.

    In my 3-year-old Samsung, there was also a fillet stain in the upper left corner (which can be seen). Well-maintained TV, not struck. Recently I approached the speaker about 60 cm. But the LCD probably is resistant to it.

    So nothing will be done about it?
    I contrasted the photo slightly

    I do not know it is a scandal that the TV would be operational only 3 years until I fear to buy some better TV for 5 or 10 thousand. I can, if I find the time, blow it with blowouts, see the highlight of the tape, etc., for the first time I see such damage. I don't even go to the website because you know nobody wants to pick up the bread and the whole matrix will need to be replaced immediately.

    I gave the TV to my mother, she does not see this stain, but recently, when I had a Samsung service technician, I told him about this problem, he said that it could be a filter on the backlight diode.
