MSI Optix MAG24C Horizontal Lines

Hello!

My display has strobing horizontal lines. This appears even without any inputs connected when the monitor shows the MSI splash screen.

Although, lowering the refresh rate of the monitor down to 60 Hz generally makes it go away. At higher refresh rates, these strobing lines are more apparent, but they DO gradually go away downward. It might take like a half hour for my screen to become clear.

While searching, I’ve seen a lot of similar looking issues for this particular monitor, but with general “try a different cable/graphics card” troubleshooting advice. I’m interested in taking this apart to see what’s wrong, but I was hoping to get some input as to what I should be looking for or if anybody else has had this particular issue.

I’ve attached a picture of what it looks like, my phone’s camera didn’t really like capturing the strobing lines, but this is it.

I’d appreciate any help or insight.

@spirrwell horizontal lines are considered to be always related to a bad panel. you should find a circuit board which attaches to the panel via very fine ribbon cables. Those are bonded on to the display so do not try and remove that board. It is the actual LCD driver board. On the ribbon cables (most likely ) you should find your Gate drivers which relate to the scanning of the horizontal part of the screen (simplified), It is most likely there where you will find the issue. Either corrosion, burned traces or many other things could do that. Of course always check your existing cables from the mainboard etc. For proper seating as well as check for tears and corrosion on those as well. Remember to post pictures on anything that looks odd or that you may have further questions about. Add those to your QUESTION since you cannot add pictures to comments.
