    Vertical stripes. They look like on a photo
    Unfortunately, the problem lies in the scalpers on the flex tapes going to the matrix. Reagree for tightening, moving the tape.
    These are scalers glued to the flex
    My question is if I can do something about it?

    Well, it's just a matrix replacement.

    That's just what I thought was a thread of it.

    But I see that this forum has come a little bit.
    Recently, I do not use much, but how many times I ask something is just such "factual" answers are.

    It was not like that in the past.
    Although technologically, it is possible to "spawn" this chip again.
    I used to talk to a Chinaman from a company that produces LCDs, but so small, he claimed that if you put a scalpel on the glass wrong, you can download it and put it back again.
    It's just that in China, it does wonders.

    greetings

    And in this particular case, what did you expect from us? ;)

    You have a matrix for scrap and a clearly diagnosed place of damage. You can test "miracles" there on this chip, until the physical destruction of the material in case of it.
    Hot winds are supposedly good for everything. ;)

    Witek, give me peace, after all, we will not make a secret of exchanging these systems. Let my friends practice and learn too.

    Okay. Will you say, should I write how we do it? Can they come alone?

    They will come by themselves, they will have enough willingness and a little practice. It's best to change two places first.
    Of course, hot-air is needed.

    These scalers glued to flex tape? This is not BGA.

    Please, write a lot more mistakes, :cry: [bogred ]

      :arrow: jfranc probably threw me out of the club.

      :arrow: moderator bogred: the answer "They're flying in balls" is very much related to the topic https://www.elektroda.pl/rtvforum/viewtopic. php? p = 11951784 # 11951784 you do not even have to change the title. It is a pity that I can not click on you helped.
