    How to deal with huge LCD screen when we are replacing the TV LED backlight?

    How to deal with huge LCD screen when we are replacing the TV LED backlight?

    Does anyone have a better way to deal with 70-inch TV or above LCD screens which are very easy to break when we change the LED backlight?

    I'd broken 10 TV screens already.

    One of my friend has 75 inch edge TV with one LED not working. I said : just leave it alone.

    Is there a better way to ensure that the LED TV screen will not break? I need 100%. I can't afford the Robot either.

      Keshenatech1:
      I've done a lot of LED strips on TV's up to 65" and haven't broken one yet. (knocks on wood lol). What I use is the front and back panels from an empty cereal box. 1st tape the ribbon cable boards to the top of the screen with masking tape being careful to not stress the ribbon cables. Masking tape is good because it removes easily and won't leave any sticky residue on the screen. Carefully work the cardboard sheets under the display glass and carefully slide all the way around to unstick any spots that may be stuck down. Then position them in the center of the top and bottom edge with only a couple inches sticking out. Then carefully lift it from underneath with the cardboard trying not to touch the bottom side with your bare hand. It helps to fold the cardboard about 2" from the edge then you can grab the edge of the screen with the fold. And usually when I do this, I have it sitting on the floor and put down an old beach towel next to it to set the glass on so I don't have far to go. The key is holding it top and bottom center, not the long way on the left and right side, or it will buckle in the middle and break just about every time. Take your time and go very slow. You don't want any sudden motion to make it bend, or even worse bump into something with it.
      Btw I found this thread because I'm working on a Philips 55PFL4901 very similar model with the exact same symptom. When I get back to the shop tomorrow I'm going to measure the voltages on the individual LED arrays and suspect I'll find a similar issue.

      I did not understanded what he was saying but I've used the cardboards to move the screens and to store the screens for later on jobs. I cut one TV box and I got two cardboards to use.

      Are there any better ways to do it?

        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,...

        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...

        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...

        Does anyone know about 16x2 LCD screens used in alarm keypads?
        by Ady2017
        I have got an old Gardtec GT595 alarm which has got a faulty keypad with a failed LCD screen. This was apparently a very common problem with these and many people have had to replace the whole alarm because of this problem. Somebody claims to be able to repair the keypads by replacing the screen and I have tried it myself by replacing the LCD with a commonly available HD44780 1602 16x2 Serial LCD screen but it is not working. I am sure it is a problem with a driver or simular which is not allowing the screen to talk to the rest of the electronics. Does anyone know what this original screen was...

        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...
