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

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.

When I turn my set on it is dark and has horizontal lines through it. After it is on for about an hour or so it gets lighter and the lines fade but it still is not a clear picture.

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.

Our three year ol Samsung TV has dark horizontal lines across the top of bottom of the screen. It is getting worse

Welcome to fixYa!

When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.

The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.

If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.

now if you can replace them your welcome but i wont suggest that , cause you may break it more....!

any ways do comment if it helped you in any manner!

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.
