Horizontal lines on my monitor

I have a Samatron monitor. It is now 3 years old. My monitor has horizontal lines on. They sometimes clear completely and other times are there all of the time. The lines disappear when viewing photos/watching videos from discs in my dvd drive. When I have looked for conflicts/sharingit comes up with I/O Port 0x00000000-0x0000047F PCI Bus I/O Port 0x00000000-ox0000047F Direct memory access controller

Re: Horizontal lines on my monitor

I have a similar problem with a 2 year old Samsung monitor. I have tried to make a screen dump of it, but the horizontal lines do not show up then. This I have read indicates that the problem is in the monitor and not the video card.

Pink and Green Horizontal lines across screen

Normally, horizontal lines on an LCD or LED monitor indicate a bad control board inside the monitor. However, occasionally the problem can be caused by loose or bad cable connections. The only things that you can really do is to disconnect both ends of the monitor cable and reconnect them firmly. Also, you can disconnect the monitor cable completely and just leave the power cable. With only the power cable attached, you can turn the monitor on and off. The monitor should have a "startup screen" or display a message that says something like "Video Cable Disconnected". If the green and pink lines are still present without your computer connected, then the monitor has gone bad. The good news is that Samsung SyncMaster monitors usually carry a 3 year warranty, whereas most monitors only have a 1 year warranty. You may be able to have the monitor replaced at no cost to you if it's less than 3 years old.

Horizontal lines have started appearing, running all he way across the monitor screen....several close together abour 3 inches from the top, and one, sometimes two, about an inch from the bottom... I have...

what you are seeing ithe horizonal sync lines, have you tried to adjust the settings on this monitor, I would try turning down the brightness, and the contrast. There should be a menu button on the monitor to adjust it.

Monitor problem


Appreciate the "Ask Me".

I am assuming that you have more than just familiarity with electronic components and circuitry, the use of a DVM and a soldering iron. Further, that you have access to a service manual.

Width problem is basically insufficient horizontal deflection, then analysis would have to be in the horizontal section. Areas to initially focus on:
  1. 12V line and pin 29 of IC401;
  2. 110 V peak to peak at collector of Q403, if yes check Q 402 & 404 as well as T401;
  3. other components that affect the horizontal size are:
  • IC201
  • Q 405, 406, 407 & 408;
  • D409
  • L401
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Horizontal lines on Screen

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Syncmaster 245B Monitor Shivering horizontal lines

Which type of video connector are you using? VGA or DVI?

If you are using VGA, the horizontal line could be due to interference, like from an electric motor (fan) near the video cable.

Other thing to try is to change the refresh rate. In Windows XP: Control panel --> Display Properties --> Settings tab --> Advanced button --> Monitor tab --> Screen refresh rate. The default ot 60Hz for LCD monitors. Bump it up to 75Hz. That could give a clue to the problem or maybe even fix it.

Horizontal lines

Horizontal blur can be caused by both a bad monitor or a bad video card/Card Slot on the motherboard.

The easiest way to check this is to connect the monitor to a known good system. If the problem follows the monitor to the good system, the monitor is bad and will need replacement. If it works fine on another system the problem is the video card/slot

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.
