          If B/L is good on that side, probably panel is bad. It looks like a panel fault to me.

                  Looking at the image the backlight is working on the faulty side as I can see the writing clearly. A panel fault is not repairable

                      You will be able to see if the backlight is evenly lit across the screen by looking at the "black glow" (the glow from the screen when displaying a black image.) It should be approx. the same brightness.

                      Panel faults usually can't be fixed as newtothis says...

                          There is too much bleed across the centre to be backlights too

                              Yea, that's my thought too.

                                  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...

                                  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 x_orange90_x
                                  Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

                                  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,...

                                  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...
