    [Video] Screen flicker

    This is happening randomly but steadily. Is it the backlight? Or is it the graphics card itself? I'd say the llater, but have no idea why. It's happening in any window, so it's not program specific.

    check the display and the LVDS cable first.

        before buying a new screen, you have to test the laptop using another screen to make sure the mainboard is fine.

          Connect to external display first and check if its flickers...

              HP Pavilion 15 bc400ns - Complete Black Screen - Only video on live usb
              by iZakre
              Hello everybody!

              To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.

              The thing is that I had installed TeamViewer and could log into the computer...

              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...

              HP gaming 15-0013dx quanta G3HA no video, screen polarize on and off loop
              by ferah831208
              I have an HP gaming 15-0013dx laptop , motherboard quanta G3HA with AMD Ryzen 5 cpu and Nvidia discrete grsphics card. The laptop turns on and u can see the screen polarizing on and off in a loop but no video signal. All voltages are ok measured and stable (I checked all with oscilloscope). This schematics don't have power sequence but I'm using a similar sequence from another laptop with AMD CPU and I get all to the point CPU must release apu_pwrok and apu_rst#, this signal comes valid only for the period of time the screen is polarized and they disappear and same loop behaviour (active/inactive)....

              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...

              Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
              by noisykid
              5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...
