I turned my monitor (Gateway FPD1975 19" LCD) on the other day and there was a thin horizontal line across the screen. itsnit growing, shrinking, getting thicker or thinner its just there. any idea what caused this andis there anything i can do about this?
I know I have seen thin lines in the past on older CRT monitors, these are usually wires which support the aperture grill.
LCD is just a panel so this must be something different. What color is the line? It is probably an error in the scanning process.

this occurs very commonly in all LCD monitors... this is because each and every cells in the LCD monitor are energized by the vertical and horizontal electric fields placed around the frame of the monitor... if a particular field does not gives the power to the associated cells to it, then the entire line of cells will not operate and together they looks like a single line...This is what happened in your case...
Although I don't have much hope for this, it is what I would try first:
Plug the monitor into a different system to make sure the problem is not from your video card or circuit.
This will probably show the same black line since the signal received by the monitor can't really cause this kind of problem.
I'm afraid that either the LCD panel itself has a failed driver (hardware, not software) or processing prior to this is faulty.
That line is being caused by all pixels being turned on hard, producing the maximum possible black.
Most all of the components inside are placed and soldered by robots and boards are often not economically repairable.
This kind of problem is becoming more common as China takes the plowshares away from farmers and makes assembly technicians of them.
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!
Disconnect the monitor from the computer and turn the monitor on it will display a diagnostic colorbar are the lines still there. if not they are likely a cable or video card. if they are still there have a tech evaluate the monitor.
Replacing the lcd screen more than likely. Problem in the PCB thats built onto the lcd itself.
They are rather inexpensive these days to replace. I would just buy a new one. Check warranties offered before buying, some manufacturers offer 3 years. ;)
I tried this and it has worked temporarily by banging the monitor not great but it did work, no tech knowledge if there is any other advise please email.
Hiyama Monitor Model: Vision Master 17 (8617E Chassis) Horizontal dark line across screen shadowing text or other complex display data - giving appearance of 3D grooves or just dark lines on light background - temp fix (few minutes) by banging monitor or jiggling the video cable (thats what threw me for a while) Removed tube base board and ran over disc capacitors and other solder joints whether they looked dry or not. No re-occurence in 2 weeks of daily use. Seems to have fixed it. (Be prepared for a lot of metalwork and screw removal when opening one of these up - I still havn't figured out how to get the PSU/main board out of one !) (John)
The screen you have is almost certainly on the way out. This type of fault is in the Horizontal Flyback section of the Monitor. Usually components fault or age and change value, these lines are normally "Turned Off" so ya can't see them, that "Turn Off" circuitry is going faulty.. it will only get worse. I suggest a new, or 2nd hand monitor as they are so cheap these days fixing CRT monitors can be cost prohibitive.
