The heatsink assembly fan was very noisy in my HP Pavilion 8563c and I assumed it was going to freeze very soon. I ordered a replacement heatsink assembly. While waiting for the assembly, I removed the left side panel to the computer and placed a 10" diameter electric fan so that it would cool the unit in case the heatsink assembly froze up. The magnetic field from the fan caused the monitor image to distort so I moved the fan to minimize the distortion. After I replaced the heatsink assembly and re-started the computer the monitor image was blurred. I turned the computer off and checked to make sure all connections were tight and that I had not inadvertently damaged anything -- all seemed OK. I was able to access the computer from another computer on the network with no problem -- image normal on the network computer monitor. Any ideas on correcting the blurred image? Thanks for your help.

You may want to try De-Gaussing the monitor. Most have a button or switch that will do that.

Did you try to switch monitors? To see if maybe just the cables need to be replaced? To touch the monitor screen with any magnetic metal or even screw drivers while their on, can make your screen act wildly. Metals can draw pixels to it, although most of the times they go back as normal. And I don't think there are any solutions to make them look like new.

If the degause button on the monitor does not work, or is not present, turn the monitor off and then back on several times.

It is possible that the degausing circuit is bad, and needs to be repaired.

Try contacting a local TV shop, and see howmuch they would charge to degause a monitor.
There degausing coil will be much more powerful than the one built into the monitor.

You have magnatized your monitor. If your monitor does not have a degauser feature you can purchase a degauser ring or loop from your local TV parts supplier. Take the degauser and starting in the middle of the screen move the degauser in small circles gradually making the circles larger until you have escaped the width and hight of the screen. This should clear up any discolored splotches or fuzziness on your screen. good luck
