I had increased the screen resolution on my computer, and then I lowered back to where it was originally. Upon decreasing the screen resolution, my screen went black. Every attempt at restarting my computer just ends up in a black screen (it will show the windows flag waving as it is starting, but it goes black after that, so I cannot get into any of my files). How can I get my screen back? The monitor also serves as a tv.

Wide screen monitor distortionDepending upon the screen resolution that has been set inDisplay, the image will be distorted on these large wide screen monitors. Create a large circle image using a draw program such as Paint (hold down theShift key as you create the circle as it will draw a perfect circle). Open Control Panel - Display - Settings tab and adjust the Screen resolutionslider, increase or decrease the screen resolution then bring the circle imageto the front and check the image, if the circle is still distorted then changethe screen resolution and check the circle again until you are satisfied withthe image of the circle. When you are satisfied then click apply.

You need to decrease the brightness of your screen by using the buttons on you LG monitor. Push the menu button and then navigate to and select brightness. Now use the left or right arrows to either increase or decrease the brightness.
If you are using windows xp then you ac right click on screen and then click on properties then increase or decrease the resolution. and if you are using vista and seven then right click and then click on screen resolution. and then according to the requirment change it.
One thing you can try is to right click your mouse, and go to properties, and lower your screen resolution settings. The higher the settings, the better quality picture, but icons and writing will get smaller and smaller. You just need to set it to something that is good for you! After you change it, you have about 30 seconds to accept your change, or it will go back the way it was.
Move the mouse so it is way, way down in the lower right corner. Place a penny or dime on the mousepad touching the upper left corner of the mouse. Pull the mouse diagonally down to the right a distance equal to the diameter of the coin. Then back up to the coin.
Take your hand off the mouse because the rest is on the keyboard.
hold <Shift> press <Tab>
right <Arrow> 10 times.
left <arrow> (decreases resolution, right arrow to increase)
By the by if you can find a monitor that will accept the resolution you selected on the 'Properties' window you can switch it back the normal way
Hence my earlier suggestion of lowering the resolution, it was actually a test.
Now we are getting somewhere. Yoke is definitely out, opposing diode pair is also out. The remote chance of the horizontal sync/oscillator is also out. That leaves us only with a possible resistor that has gone up in value (or is open) (least likely) and/or a capacitor (most likely) that has leaked, bulged or whose capacitance has gone down.
