    Can't quite see what you mean, is it the vertical lines you are concerned about? Is the picture otherwise ok?

        I'm going to say panel possibly tab bonds, is there one area that is continuously white?

            Could you record a video of the whole screen doing what it does?

                  Looks like a bad panel, maybe worth trying tabs but I would be surprised.

                    I tried reseting the tab tcon board still same i did look at tcon see if it was getting power.looks like it is also checked voltages on spots from tcon to panel ribbon.they have voltages also two caps c1 and c2 .c2 has 15v and c1 has 3.3v.there is also ka1718 mosfet maybe regulator center tab 1.216 left tab 2.651 and right tab 3.313 fuse 11.87 on both sides.do these reading look good if so that way i can say it is a bad panel.

                      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...

                      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...

                      by Zilicon
                      Please help:

                      The above laptop with the board number: "GK5MP5X MB V1.0" started with the screen becoming blank when a game was launched, or a higher definition video was being played. It became worse by not displaying at all during boot up, but there are signs that the PC was working every other thing worked except the display.

                      The PC works normally with HD screen (720p) but no display with a full HD screen (1080p)

                      I couldn't find any boardview or the schematics for the motherboard.

                      Please, how do I solve this problem

                      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...
