It should be still inside somewhere as it couldn't easily get out of the monitor case. If you can't see it, turn the monitor upside down and shake it! You may need to put the back on and give it a few bangs in different positions until you hear the rattle you are longing for :^O If you can find it, try gluing it back on but make sure it is oriented as it was originally (glue marks may help). If you can't be sure how it should be oriented, try a few likely ideas using blu-tack or similar to hold it in place and check the results on screen before permanently gluing it back. Cheers Billy 8-{) :D PS Graham, Horizontal keystoning is typically caused by impedance differences between opposing horizontal scan coils and maybe your computer has a minor manufacturing tolerance issue between scan halves. Sounds like you may have to live with it, but you could try any screen tilt or pincushion adjutments just for fun as there may be coupling between the effects and a compromise could be achieved.

90570	2002-11-03 00:29:00	Hi Billy, it's me again. (Do you remember the monitor that was missing a ferrite magnet or passive inductor?) Well, after your last email, I took notice of your advice and went left right and centre to all the tv and pc repairers around here, (not many I must admit), but no one seems to be either able or willing to help ;\. It appears to me that I will have to do some search and research for the part myself. Now in your infinite kindness :D would you be willing to help me once again and direct me to how to find the part? Thank you again for your help.	Sanco (683)
90571	2002-11-03 03:37:00	Hi Sanco Did you have a look inside to see if you could find it? (assuming that it was there originally and has simply fallen off). If you don't want to take it apart, try turning it upside down or on its side and shaking it to see if it will rattle. If it does, go back to my earlier advice, find the bit thats rattleing around and see if you can find where it came from. Cheers Billy 8-{)	Billy T (70)
90572	2002-11-03 06:30:00	Hi Billy, yes I have had a look inside and quite thoroughly too, I shook it, turned it upside down etc. I even took the monitor to several "repairers" and got a vast array of opinions on what that magnet's role was. Some have hinted that maybe the magnet has nothing to do with the skewering of the image and so on. The only way to find that out would be to install another one in of the same kind and see, I believe. Would I be wrong in assuming that? But the problem now seems to come down in finding another one to install. So if you have any idea on what I could do it would be much appreciated. By the way my monitor is a Compaq MV540 15". Thank you again for your time and help.	Sanco (683)
90573	2002-11-03 08:11:00	Well Sanco, I'm at a loss to know what else to suggest. The problem with remote diagnosis sight unseen is that we could be barking up the wrong tree altogether. There's just no way to be sure. The only other option would be to find another monitor of the same model to compare, but that kind of defeats the purpose of the exercise. If the distortion is sufficient to cause problems, perhaps it might be time to pick up another monitor, perhaps a 17" to increase your screen real estate. If it happened during a move, perhaps insurance might be worth considering if your excess is not too high. Good second-hand monitors can be bought quite cheaply via Trade & Exchange so that might be another option. Cheers Billy 8-{)	Billy T (70)
