White line on my LCD Monitor Screen....please suggest any solution

[Siddharth Maurya]

My Computer is working very well, even my LCD monitor displays all things without any problem. But after 5-10 minutes from startup of PC I see a blinking horizontal white line at the bottom of my screen and after some time it becomes a permanent white line at the bottom of my screen, and it looks very annoying to me..so tell me if I can get rid of this.

I have LG 20" inches lcd monitor (Model No. W2043C)

I think there is no problem with my GPU as when I disconnected my D-SUB cable it shows "NO SIGNAL" message on my screen and there was still same white line at the bottom of the screen.

is a monitor issue for certain being you disconnected the video cable but still have that line on the screen. as that monitor appears to use a regular power cord not a power adapter means there is 2 boards in that monitor, a power board & a video controller board, I think the video controller board is causing the problem. how technical are you?

Not much technical.... can play with some softwares, but that depends on the problem....can you tell me if there any solution to this? I'll try if I can.

Update: Ooops...you told me about power cord...now I remember, power cord of my PSU unit and of my Monitor looks same so may be they got replaced...so now I'll replace them again...and I'll tell you if It worked or not.

Update 2: it didn't work..

yes by taking the monitor apart to look at both the video controller & power boards.

Did you try to manually reset the monitor to factory defaults? Try to run it on another computer, see if the issue carries over.

demoth, trying it on another computer won't do any good if it still has the line on the screen when both connected & not connected to a computer.
