    Welcome,
    TV as in the subject, I have it for a year - bought second-hand, so after the manufacturer's GW. Yesterday I got two x-rays on the matrix as in the pictures. It looks like the LEDs illuminating the screen are illuminated to the max (if in this model the backlighting is implemented under the matrix)
    In the case of a dark background, the spots are hardly visible - in the case of light colors - very much.

    Has anyone encountered such a problem?
    And does the repair involve the disassembly / dissection of the matrix? As you know, this is a curved matrix, I wouldn't want to break it down

    Regards

    Believe your colleague higher and do not check by shaking the TV if something is flying inside, because you will have the entire collection to glue. ;)

    Rightly. And I advise you not to do that. It is better to ask a good specialist. :-?

    Sticking is not the end, centering the lens so that there is no glow is already a higher driving school. Especially these large lenses, found among others in LG.
    It is not easy, but I have probably developed a patent, as I will have the opportunity to check and describe.

    OKAY!!
    Thank you for the info, I have replaced polarizers or fluorescent lamps in matrixes but all of them were matrixes up to 16 "... this one has 55"

    One more question ... what could be the reason for detachment? Is there an increased risk of unsticking after repair?

    Sometimes it is enough to sneeze in the next room and they fall off :) Not to mention the earthquake, etc. cataclysms.

The user suspects that the issue may be related to the LED backlighting, which appears to be excessively illuminated. Responses suggest that the problem could be due to the lenses from the LEDs detaching, and caution against attempting repairs without professional help, as disassembly could risk further damage. One participant mentions the complexity of centering the lenses correctly after reattachment, indicating that this is a challenging repair task. The user also inquires about the potential causes of lens detachment and the risk of recurrence post-repair.
