Display issue on LG Flatron L222ws

Hello,

I recently encountered some display issues with my LG Flatron L222WS monitor, which is starting to show its age (around 3 years).

Let me explain: The display works normally on about a third of the screen (a band at the top), while the rest refreshes irregularly, then freezes before gradually inverting the contrasts (only in that area, with the upper third remaining normal).

At one point, I was able to stabilize this issue by fiddling with the connection (on the monitor side). However, this 'technique' has started to prove less and less effective. I then changed the cable connecting my monitor to my CPU, but the same problem persists. Being reluctant to invest in a new monitor until I'm certain that the current one is beyond salvation, I'd like to know if any of you could indicate whether the issue simply stems from the connection (in which case, if someone could guide me on how to change it or have it changed, I would be grateful) or if my monitor is in a semi-terminal state against which I can no longer do anything.

Of course, if you think the cause could be something else, I'm open to that as well.

If you need more details on any point, feel free to ask (though I'm not an expert in food for penguins with mittens).

Thank you in advance, Best regards.

Configuration: Windows Vista / Safari 535.7

    You have done your "investigation," so... we just need to find out if the cable is removable or if it runs with the screen...
    If it's no longer under warranty, you can carefully open it; it’s possible that 2 or 3 capacitors are dead... which means you’ll have to desolder them and solder new ones in their place... do you feel up to doing that?
    Otherwise, given the current prices of screens and labor costs in this field, I think it’s better to go for a new one, but well....?!

      Given that the cable is detachable and the screen is no longer under warranty, I will try to open it and see if anything obvious might catch my eye...

      In the meantime, thank you for the advice ;)

    Hello...

    The first thing to do is to connect this screen to another PC, or another screen to this PC... that will pinpoint the problem....

      I indeed forgot to mention this, I am currently using the same unit on another screen, and it works perfectly well.
      Additionally, I tested the screen on another computer, and the problem persists, which is why I think the issue comes from the monitor. But I'm not able to say if it is repairable.

    Just because... since the cable is removable (on both sides, I mean!), try putting another one in, or check the 15 pins on each side...

    Well... just the disassembly and checking of the capacitors left...! ;)
