    Lenovo L2240pwD ghosting or fade image

    Hi, thanks for your help

    I have a Lenovo monitor model L2240pwD, which in turn has an LG LM220WE1 panel

    The problem I have is that after a few minutes on the image is distorted, like it fades or has ghosting.

    I have never repaired an LCD so I have no idea what it could be, if you could give me your help I would greatly appreciate it

    I attach photos of the board that this monitor uses.

      Do you have the same problem using the DVI input.
      What voltages do you have on U101 and U102 and do thy change as the picture fades.
      Is there a power supply board for this unit or is it an external power pack?

          Lenovo X240 - motherboard replacement for X250, no image.
          by andrhouseolly
          Friends. I beg you to help me in this situation.
          Lenovo X240 with a video problem. Native Intel drivers are not installed,
          after installation, a black screen. It works with the standard Microsoft driver.
          Understanding that there are problems with the video core,
          I ordered a motherboard from Lenovo X250.
          The laptop turns on, starts up, there is no image on the internal display.
          The image is output to the external monitor.
          I ordered another motherboard from Lenovo X250.
          The laptop turns on, starts up, there is no image on the internal display.

          For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

          Searching for recent BIOS image for a Lenovo p43s
          by Ian Slinger
          My p43s recently died - the classic "ESC, F1,F4, Capslock lights" issue so it won't even POST.

          It's possible there was a glitch during a firmware upgrade so I'm looking for a recent BIOS image to reflash with. The Lenovo site provides plenty of EXE and ISO files to recover but of course it won't boot so they're useless.

          A search on Badcaps doesn't seem to turn up anything specifically to do this, for example a .BIN file. Going by the designation on the Winbond chip it appears to be an 8mb image.

          Am I missing something?
