    Another Screen Question

    Hi

    Just a quick question and to get a bit better understanding of when/why screens fail, did read a post that tom replied with how they work which was very educational.

    What I cant get my head round is for example

    you turn the tv on, the screen is shadowing fading in and out, white patches appear etc etc..leave the tv on for 30minutes doing this then all of a sudden you get a cracking 1080p picture that looks perfect.

    Why do they do that? And is this always a fault with the lcd panel (and a tab bodge didnt fix it)

    Thanks in advance

      Heat. Things expand when they get hot. The loose contact somewhere finally makes a good connection.

          Fully understand, but!

          When you turn the tv off for 1second, turn it back on and have to go though the same 30minute cycle until the screen is perfect again, it surely cant of cooled that quickly

              The devices are very small (contact area of a few hundreths of a millimeter) so yes, they can cool that quickly.

                  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,...
