      Try to reflash bios, but first change RAM.

              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...

              RedmiBook 15 pro 2023 Ryzen - after replace LCD screen work only in windows
              by benek123
              I replaced the screen and LCD ribbon in Redmi Book 15 Pro Ryzen 2023. After replacing, the image on the screen is only visible in Windows 11 - when the AMD drivers are loaded.

              The screen is backlit but there is no image in: bios, post, when loading windows, in linux (ubuntu boot from usb), windows 10 PE.
              When I disconnect the EDP connector from the board and connect the HDMI cable, the image is visible everywhere good, in the BIOS you can see 2/3 of the image, i.e. 1920 pixels out of 3000 pixels.
              I checked the EDID with the old screen - it is identical.

              What...

              HP Elitebook Screen blank - backlights but no image
              by dicky96
              Hi guys
              I'm trying to fix this laptop screen

              Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

              OK so I have the original screen which works but has lines across the bottom quarter of the screen

              I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...

              Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF OLED Blank screen
              by Kalman27
              We have a Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF for repair. The original issue the OLED screen is blank.

              We have replaced the OLED screen with the exact model, also we replaced the LCD cable, but no luck.

              I think there is something with the motherboard. I don't really have experience with OLED screens so far, so not sure how it should work. I have seen some laptop comes with a separate controller board, but this model does not.

              Also, there is an error in Windows device manager - This device cannot start (Code 10) - Intel(R) Serial IO I2C Host Controller...
