    Where to take apart laptop LCD - need ideas

    Hi everyone, this is my first post here, and i chose something different than bad capacitors for a change. I have a HP dv9000 laptop which has acquired some nasty dust specks inside the LCD over time. I don't know where they come from but all my laptops have suffered from this. I've read about someone with ANTS inside his screen so it seems this is rather common.

    Anyway, last time i took apart a LCD was on my old Toshiba Portege. It ended up messier after than before. I don't want the 9000 to end up the same, but a new screen is just too expensive. And those spots really get on my nerves sometimes.

    So, any tips on taking this screen apart without getting it filled with more dust? The spots look a little blurry so i think they're on the last foil, that is the reflective layer that covers the backlight, so it should be easy access. I was thinking on opening the screen just slightly and vacuuming them out, as all three spots are near the bottom of the screen. But i somehow believe it won't work.

    Anyway, does any of you have a theory on how the darn things actually get there? Mine is that they are there from the factory but they are on the edges of the screen, and they fall by themselves at some point or another. My other laptop, a dv5, bought new, came with one tiny speck on the left side, haven't noticed any new ones though. I'm curious, if i'm right and they fall by themselves from the top, why the heck do they get stuck???

    Leave it, there is nothing you can do about it.

    You need to completely disassemble the screen and its diffusion platters for the light.

      I know that, i told you that i did it before and it didn't end up too pretty. But by the looks of it the dust specks are on the bottom foil (or platter if you like to call it that), so there shouldn't be THAT many surfaces to watch for.

      I've seen a clean room project on hackaday if i remember right... Before i build one of those, i won't be taking my display apart anyway.

        Well, it is just that I've tried that and it has ended much much worse than before.

        Dust is everywhere and especially on the edges of LCD. It will get once you open it.

          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...

          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,...

          Trouble to identify part (Lunii screen) for replacement
          by FreakyMex
          Hello guys. I'm a complete noob in electronics. I'd like to repair my child Lunii's (a "story box"), basically an audio player that allows the childs to choose between several options the places, characters, objects of the story, and then play a story according to the choice of the child. There is a screen that display the selected option before each choice. The Lunii fell and the screen is now broken.
          I'd like to repair it (probably just have to change the part, because the lunii still works perfectly fine) but I can't manage to identify the part/order it online. Do you have any...

          by HTR-Informatique
          Hello,

          YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

          I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

          On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

          I also changed the screen because the PC fell and the screen was broken.

          I changed the battery with a new and original battery.

          I also had corrosion/oxidation on the...
