    Hp vs 19

    I have a totally white screen, wife came in to do some work and she fired up her computer and only one screen works correctly. I had repaired the caps around 4 years ago, thing it might be the ribbon cable possibly loose. I took the back off and the cable was secure. I searched the forums here for any knowns but am not able to see anything matching.
    Are there any known quick fix concerns

      Ok, that ribbon cable (LVDS) connects to the panel board. You want to look for a a fuse and check it. Also check the power to the fuse with the monitor on. You may have to remove some tiny screws to gain access to the panel board. If you need to fold it back, be gentle and make sure you don't damage the little ribbons. (TCP)
      A white screen often means a bad fuse on that board. (or no power to the board)

          now its just black. I plugged the chassis in and was working the switch, the backlights would light up and then time out. I may touched something incorrectly now all is black

              What were the capacitors' brand and model/series used for replacements? There are many causes for white screen ranging from noisy power rails (due to badcaps) to faulty Tcon board on the LCD panel (for example, check the fuses on the Tcon board)...

              This one sounds like "2 seconds to black" symptom...

                  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...

                  ASUS X54H laptop no backlight
                  by flat-earther
                  Once upon a time I was casually browsing the World Wide Web with my ASUS X54H laptop which was sitting on my desk, when suddenly the screen turned black!
                  After several seconds, the screen turned on again! And so I continued to use my laptop as usual.

                  Some time later, the screen went black again! And it hasn't lit up since.
                  So here I am on a journey to repair it.

                  Not being an expert on how to repair, what I have done is searched the internet for help on a laptop screen not working, and I have checked some things.
                  I found out that with a flashlight...

                  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...

                  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,...
