I have a very wierd problem, sometimes I turn on my iMac and the screen is out of focus. Do you have any idea why this is happening? I do not wear glasses, and I was using a computer an hour ago an it was not out of focus. So its not my eyes, Help!!!

After awhile it comes to focus.

Stop taking the drugs.. :D

What kind of iMac, how old, you know the routine... if it is under warranty, have you called Apple yet??? Most likely you will need to.

Could be that your screen needs degaussing - a procedure that realligns the tube's magnetic field (and colours) via use of a degaussing rod, which is really just a glorified electromagnet.

Don't try this at home, kids - magnets could screw up your monitor for good. Therefore, I suggest the use of a specialist in the field.

Example: I remember when I was a kid in New Zealand, and was walking around the Audio Visual section of a Department store - having all sorts of fun by putting my toy magnet in the centre of the TV sets and watching all the colours get "sucked in" to the middle of the screens. FUBAR... ;)

Most monitors (at least the decent ones) have a degauss option via the on-screen controlls. I don't remember if the iMac (crt) gives you that option via the Monitor control panel, but you might want to look.

Which iMac is this happening to??? IF it is one of the new LCD models, then you will have to take it to Apple (or an AASP) for repair. I'd still suggest CALLING APPLE to see if they can walk you through some resets (such as the open firmware) that could resolve the issue. To do that one, just hold down the option+apple+o+f keys on startup and when it gives you the open firmware screen type in (sans the quotes) "reset-all" and hit return/enter. It will reboot the system. That COULD fix the issue.

Pishah!! (as I pop a tab) Drugs can be great!! Just ask Steve Jobs.

Seriously though...I do believe that the iMac has a degaussing option. Try it.

Macmaniac...New tar? I liked your one with the guy on the red background (no animation) a lot!! In fact...It's one of the better ones I've ever seen! I don't know why, but it seems to fit your macrumors name perfectly.

Dude, can't you take a JOKE??? :D <-- big clue to when I am joking :rolleyes:

As stated before, check for the degauss option under the monitor's control panel. Also try the reset-all from the open firmware. BOTH very well could fix the issue. If not, then it will need to go in for service. Do you have Applecare protection on it?? If not, and you still have time on the first year warranty, get the Applecare added to it. THAT can save you some serious $$ on repairs in the future (as well as give you peace of mind).

what do you mean it's out of focus? like the screen isn't the right size? because my monitor (iMac 600) after night's rest or something, the viewable area is higher and narrower than what I set it to, then it levels out after a while of being on...is this what you're talking about?

I had this same problem years ago with an original Bondi blue iMac. There was a way to degauss the screen, but I think it was pretty involved and not accessible through software means. I remember the cheat was to open the CD drawer all the way, and push down on it slightly. On most of the earlier iMacs, it would get the screen to degauss. I am sure there is something somewhere that tells you how to deguass the screen on that iMac, but if you still have the Applecare I wouldn't even waste time looking for it...just take it in.
