Question Samsung monitor has horizontal lines on the screen ?

[bedouinbro]

Monitor: Samsung T55 Curved 27 inch

Any idea what's causing this horizontal line? I tried all the refresh rates & resolutions and resetting from the monitor's OSD, nothing worked.

Might want to connect the display to another machine/display source/GPU. If the display behave the same way on another system, then your display is saying I'm on my way out. I had a similar line show up on my Samsung P2350(yes it served me a long while) until there grew a white hazy spot in the middle of the screen then the display went out.

I dont have another output but it doesn't appear in the screenshot:

I used a Samsung S19C300B for 10 years before it died on me -)

Is there any way to prolong the life of this T55 monitor ?
It's a used one i got, so no warranty there but it's not that old to be dying this early.

Using the Samsung T55 27" monitor, a horizontal line on top has appeared and the screen is flickering. The default refresh rate is 75hz, when reducing it the flickering goes away, 47.5hz is the lowest refresh possible, but after using the monitor for a few minutes the flickering comes back,

I opened the monitor and reconnected the panel cables and the tcon board/power board/ there's only a single pcb in there. even without the hdmi the horizontal line remains.

below are two video examples

is it possible to fix it by taping the panel cables ? the horizontal line ? or the board needs to be repaired or replaced ?

lol, thanks i guess, but is the monitor fixable by taping panel cable or the tcon/power board is gone for real ? i asked chatgpt and others, these bots says the board components are failing

i removed the ribbon cables and from one side the horizontal line is gone, i found some videos on youtube about applying tapes on the ribbon cable, i tried and in one case i got black screen and on another the same horizontal line with left side of the monitor white out, any idea what to do ?
