    LG 49LB5550-UY Fixable??

    Hello all, brand new to this forum and all this tech repair. I've always been interested in tech and learning more than than average person and well, I guess this is my chance!

    - Forgive me as I will likely not be using the proper terms throughout this post, again, I am a newbie to all this!

    I noticed a few "LED Bulbs" falling out of place behind my TVs screen a few weeks ago. After some research I find how to quickly glue them back into place. I finished the work and when putting my TV back together I accidentally cracked the very corner of the display ��. Very sad.

    After putting everything back into place and turning on the display the displayed video now jumps around everywhere. After more research I found this could be due to some "bad ribbon display connection" - the gold pin things that some people cover with tape for a quick cheap fix. Well I don't think this is the problem as I tested both ribbons and bith sides of the TV display a white streaky picture. I believe 1 ribbon would display half a perfect image and the other ribbon display a half faulty image. I am not 100% sure on this though.

    So my primary question is this - does the crack along the edge of the display cause the screen to jump around and if so is there a repair? I understand that the crack itself will cause a black spot on the display (which you can slightly see in the video) that is likely not repairable and that is okay, I can get past that small black spot. It is just the display jumping around that ruins the entire TV.

    I've uploaded a few pictures and a video. Hopefully this helps. Please advice as what I can do if anything or direct me to a helpful resource. Thank you so much!

    EDIT: My MP4 of the jumping display will not post. Have uploaded a screengrab of the video for now.

    The best option is probably buying a new TV

      I plan on doing this very soon. But was hoping I could make this TV at least useable as a secondary TV for the house or maybe our guest room.

      I will be buying a new TV, but do you know if cracks on the edge of the screen cause jumping and if so, is it fixable?

        These LG screens are probably the strongest I've seen. You tried really hard to break it

          Yes the crack is the reason, you could try seeing if circuits are present in both the sides, or only one, you see it if borders are different, in that case you can try the tape masking method or you can remove the broken corner and massage the broken profile to clean it..

            @davi.p - I'm as beginner as beginner gets on TV repairs. I appreciate you answering my question about the crack unlike the previous posts. Thank you for confirming that for me!

            Now in regards to the fix. Are you able to point me in a direction or a link for a tutorial or example about this tape method you speak of? I can't find anything related online or YouTube and I'm sure you don't want to walk me through every step

            Any direction is appreciated. Depending on the complexity of the project I might just donate or trash it. Thanks again!

              there's no direction to take, tape method IS NOT for a broken screen, THE END. Post #2 was the best advice.
