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.

Re: Brown horizontal lines sporadically appearing on...

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.

Re: Brown horizontal lines sporadically appearing on...

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.

anything can be repaired if you have the money and are willing to spend it. However it would be better to get a quote and weigh up the pros and cons of replacing it cheaper than the repair A new monitor wilol also have 3 years warranty ( Samsung)

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.
