If this is a CRT, then the horizontal deflection circuit is faulty.
The repair is generally not worth on CRT.

First try leaving monitor power cord unplugged for few hours, to discharge capacitors, sometimes this can fix minor problems.

Test also the display on different computers, you never know that this depends from a faulty video adapter.

More likely you will need to replace the screen.

My Samsung SyncMaster 2463UW no longer auto detects the video input. I normally use it with my MacBook Pro - I turn it on, it detects the digital output and Bob's your uncle. Today, I turned it on and it continues to cycle through analog, digital and HDMI input sources. However, I can actually see the correct output when it switches to ''digital'' mode - it just won't stay there.

The power light blinks solid blue every four seconds or so (it?s off in-between). The screen is blank. None of the buttons on the side function (such as ?menu?). I have a second similar monitor from the computer in the other room I?m using to type this proving the video card and cable are fine. We?ve always (as in years) left the monitor on (w/ a screen saver) but for whatever reason turned it off for four days when we went away recently. The monitor would then not turn back on.

Faulty Monitor? I bought one of these Xerox flat panel 19 inch monitors to replace my convention Sony unit about 4-5 months ago. It has worked just fine until about 7 days ago. Are there any known problems with these Xerox units? I turn my computer off during the day, when I am at work. I also turn my computer off during the night when I am asleep. At those night times I also turn the 'blue power button' on the monitor off as well, as it will flash annoyingly in the room if left in the 'stand

Samsung Sync Master 914 has no picture. When power supply is only in, green light flashes slowly. When both power and vga are in, green light flashes more quickly. I hear a faint clicking sound coming from the LCD screen when out of case (located top right corner when screen side is down). Screen flashes faintly (only really noticeable in the corners)and coincides with the flashing of the green light (even with green light being unplugged.) No caps seem to have issues.

I would check the caps with ohm meter. Make sure they all show increasing resistance. Caps can be bad without looking bad. Check output voltage on the power board, should be around 12V. If all that checks out then I'd look next at the backlight bulb. ... Computer Monitors
