    Screen reconditioning (slightly off topic)

    I have a 32" LCD that I repaired the power supply on to resell. I didn't notice the deep screen scratches till I had already gotten it home. They were noticeable, so I polished them out carefully with a dremel and polishing compound (they were much too deep to do it by hand, and the polishing did work actually). Now the scratches are gone, but the polished areas are very shiny because I polished off the matte screen finish. The Tv looks perfect from certain angles, but terrible where you can see the reflections off the polished areas (its very distracting and unattractive when the tv is on and in a lighted room). This is just a fun project, so I'm not too worried, but does anyone know a solution for this by chance? Any ideas at all? I can give some attempts and post results.

    Thanks

    Why not polish the whole thing to at least make it uniform?

      If you have not buffed thru the polarizer all the way to the glass, I would suggest trying something like 800 grit sandpaper, but not sanding with it...try rolling it on the shiny spot in hopes of roughing the polarizer up somewhat. Sort of like rolling your finger when having your fingerprints taken.
      Just something to think about trying...

        Whatever you end up doing, be sure you only mess with the anti-glare coating. If you accidentally cut into the polarizer (which is directly under the anti-glare sheet), areas with no polarizer will show up as white.

          weirdlookinguy... do you mean that if I have gone all the way to the glass, there will be no image at all in those areas? only white? That isn't the case as of yet. I wasn't aware that would happen. I thought that after the anti-glare there was the actual glass.

          I have thought of polishing the whole thing, but am leaving that as my last resort option, because after that, I have no options. (it will be very time consuming if that's what I do)

          I went ahead and tried roughing up the shiny spots. It was to no avail though. Nothing changed (didn't really rough up at all). I thought this meant I was to the glass, but I guess not if weirdlookinguy said is true.

          Is there a chance the "polarizer is under the glass, and I need not worry about it? (I'm not too familiar with LCD construction I guess)

          good ideas though, any more?

            you could ask at lumenlab.com. they're into projectot building and mess around with that stuff a lot.

            there's a polarizer on both sides of the glass, so a definite no to that question.

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              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...

              iphone XS turns off when press on screen.
              by smic717394
              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...

              Samsung UE55JU6800K half screen dark
              by Chrissygizmo
              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...

              Vizio TV M50-C1 reboot cycle and static on screen
              by spice_disc
              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...

              ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
              by ipatch
              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,...
