    LCD screen layers...

    Well, I guess I got pranked.

    I was holding an LCD by its base, but someone pulled the screws out unbeknownst to me. The base slipped out of the main cabinet and started to fall to the ground. Yow.

    I quickly tried to grab it before it hit the floor but instead the screen hit the piece of the base that I was still holding, scraping it!

    Now I suppose the scrape is better than the display hitting the floor but it still is a scrape...any suggestions on how to fix this? It seems to be a matte display and got gouged fairly deeply but the liquid doesn't leak out.

    Sounds like I need a whole panel to fix this ? Or can the top layer somehow be replaced?

      I've seen youtube videos on replacing film. Don't know were you would get polarized film
      I assume no responsibility for any stupid suggestions I might post.

          It's properly bonded to the glass, I doubt you could replace it, if you could it would be like replacing the touch screen on an AMOLED phone (go very carefully with a hot air gun and peel slowly) but on a massive screen, I would not like to do that!

              Just search for" replacing lcd polarizing film" lots of videos like these examples, like dskall said, finding the film might be tough, check this site http://www.lcdparts.net/Film3D.aspx
              some videos here

                  Ah interesting. Sounds like I'm stuck with the scratch

                  Oh well, at least it still works and no crack, though it is very visible *sigh*

                      Can't "buff it out" with some automotive rubbing compound?

                      Don't know if I'd even want to try that, lol. but maybe if you tried with a q-tip on a tiny part of the scratch. I'd probably try horizontal and vertical, rather than circles(?)

                          i'm currently doing an experiment on a screen that is scratched. i'm sanding the surface and then clear coating it. not sure how it is going to pan out yet.

                              OOSH! Id start on a small corner that you wont notice. Or maybe on just a tiny part of the scratch.

                              I wouldn't want to EFF it up by jumping in feet first and doing the entire thing.

                                  my test unit is one that has a tab bond failure that i can put pressure on to get a clear picture, so it is the perfect candidate.

                                  i'm thinking that i'll need to use a matt clear.

                                      It's a polarising film, put on for a reason. Matt clear will not deflect the light as the film does.

                                          that is very true. luckily i would not be removing it. it is the blending over the scratched area that is the only real concern.

                                              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                                              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                                              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                                              Hi,

                                              I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                                              Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                                              I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

                                              I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

                                              The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

                                              i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
