Brown horizontal lines sporadically appearing on monitor

I have brown horizontal lines which appear on my monitor sporadically. This problem is getting progressively worse. I have tried moving the phone and all other electrical appliances which are near the monitor, but nothing seems to reduce the problem.

    Now all the screen is often suddenly covered with a flickering sepia coƩor -when it clears the CRT is perfect.There is nothing near the monitor -a Samsung 795 mb 17inch.This problem is getting worse -it must be fairly common with so many monitors out there-can anything be done? Ive tried switching the monitor on and off quickly -sometimes this seems to work but not always

    Please help -if possible!

Mine too, Samsung 793 DF, started doing that 4-5 weeks after purchase (Sept. 05 brand new). I complained to Samsung, got the refurbished one, CRAP, returned it back and kept the "faulty" one.
Otherwise, very good colors and no other problems whatsoever.
Yes, it is getting worse and even after 1hour it comes back once in a while - manly from the text characters on the white background.
Probably generic problem, and not worth repairing since repair would cost more than monitor itself - unfortunately.

    Mine too, Samsung 793 DF, started the problem within few months after purchase (2005 brand new). I complained repaired by the seller within warranty period. But after 1-2 yrs it begains again and continue till now for few minutes after start up. Duration is increasing trend.




I have exactly the same problem with the identical monitor, but I have not found any solution. It seems to be the monitor causing it because I can't see the lines, when I make a screen dump.

Brown horizontal lines which appear on my monitor

Hi there and welcome to Fixya.

This type of issue is geared towards hardware problem you only need to verify it by doing the following:
  • Make sure the computer is turned off
  • Turn on the PC and immediately tap on "DEL" key repeatedly (on some systems, it's "F2")
  • The BIOS screen will appear (not the windows logo), here, you can stop tapping on the kybd.
  • Spend 30min or an hour with the BIOS screen and check if the lines are still present
If the problem persist, then it's definitely a hardware concern and the monitor needs to be serviced. Please understand that there's no DIY solution for this unless you are a certified/trained monitor techninician.

I hope this helps, Thanks for using Fixya.

My nokia 6500 slide, has some problem with its screen. first it was a light brown symbol on the screen and later, two lines appeared to the left side of the symbol horizontally. and now, one more line...

Hi, You will need to unscrew the phone and see if the phone screen is not broken, if the screen is not broken, that means the fllex of the phone is damaged and will need to be replaced.

The flex controls the displaying of the screen.

Horizontal line appears even computer is off.

Unfortunately that means your monitor is in need of repair.Most likely you will have to consider replacin the monitor as a 17$ most likely isn't worth the price of repair.

Brown horizontal lines sporadically appearing on monitor

I had the same problem. I fixed it completely today. The horizontal lines disappeared. IT IS DEFINETLY THE DEVICE DRIVER. I confirmed my monitor model tyope (dell M783s) and downloaded the specific driver for this monitor.

I had to do these exact steps or did not work.
1) with the problem screen, disabled the display adapter under the Hardware/Device Manager settings.
2) Restart the PC
3) Boot will come up with brown lines still but the screen will low resolution of 600x800.
4) Then I installed the correct device display monitor driver onto the pc. ( you may need to scan for new hardware, then choose the directory with the new hard drive.)

If you need step by step... just reply back.

Horizontal lines are appearing and moving acrosss the screen of my View Sonic E50C Monitor...

What is wrong with your monitor is that the Horizontal section is going faulty, the lines you are seeing are the Horizontal Retrace lines, usually invisable in a working unit. It is often a faulty capacitor(s) OR a Diode breaking down.. in the area of the Flyback Transformer. Probably time for a new one unless ya can fix it yaself.
