    "poor Screen" on a Xerox 700P

    Hallo,

    after connecting a Xerox 700P to the computer, I got a very poor screen-picture. That seems similar to 8-bit resolution, but is for sure something else. Is that symptom known by someone? I put 2 pics into the attachment.

    Cheers

      Have you tried changing the resolution(s) on the computer's video card?

          Hi jetadm123,

          yes of course I did. That was one of my first thoughts. But the resolution during this two pics were made was 1280x1024 with 32-bit colours. That is definitely not the errors cause.

          Cheers

              1) A long shot would be that one of the voltage regulators on the main board is running out of specification.

              2) You can always try cleaning and reseating all the internal cables.

                  Hallo retiredcaps,

                  thank you for your "tough-tip". Actually the item 2 was the bug-killer. I repluged everything on the mainboard and also put the MCU out of the socket for to polish the contacts. After back plugging I got full colors! Great!

                  Cheers

                      Hmm, jetadm123 started around the same time and I think it is safe to say that we have never heard anyone takeout the MCU out of the socket to clean the contacts.

                      Glad you got it going.

                          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...

                          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...

                          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,...
