Remove the back and check the ribbon cables on the left side that is in-line with the the black bar and remove it and on the other side of the cable there could be a couple of components that need ton be re soldered, or just clean the connections.

There may be a few issues her, try changing the contrast andbrightness of the screen, this can be done by using the buttons on the monitor,check any documentation you have if you're having trouble. If this doesn't fix it could be a monitor problem for your videocard itself. Try using another monitor,if possible, to test your video card or try your monitor on another pc/laptop. If the monitor works fine on another machine then chancesare it's a problem with your video card, it may even need replacing.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:

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!

No, this is not normal. This could be one of two problems. 1) internal connection to the "Y" array is somehow been compromised either through some defect in manufacturing or simply a loose connection. 2) The LCD converter board in the monitor is defective. In either case it's internal to the monitor and would have to be serviced. Have you checked with HP to see if the device is still under warranty? It just might be If not, you can try opening the unit and checking the connection on the left hand side towards the area you mentioned. But beware that the monitor does contain leatal voltages.

Blurring of images and text

mt, the 6 to 8 lines you were seeing were most likley the prelude to the end of the monitor. If the problem only occurs when the screen saver comes on then I could say the driver maybe being corrupted by a certain screensaver picture or program. When the monitor warms up to a certain temprature the electronics start to fail. You may want to turn off the monitor while your not right in front of it to cool it down and prolong its use.
