I noticed a weird problem on my Mac+ the other day...it seems that the screen
has gone non-linear....that is, things on the left side of the screen are
wider (but the same hight) as things on the right.
It's like the pixels are getting closer together horizontally at the right
side of the screen. It's not a BIG change yet, but you can notice it very
easily when you drag an icon from one side of the screen to the other.
The change seems to appear only in the far right...move more than an inch or
so to the left and it goes away.
Is this the first warning sign of some kind of impending doom?? Anybody
else had this problem or know what can be done about it?

But it was a minor problem, really. A capacitor on the analog board went bad. I'm not a hardware expert so I can't name which capacitor it was, but it was a black one at the top of the analog board towards the front of the screen if you stand the Mac upright. I had mine fixed in 15 minutes. _______________________________________________________________________________ Dean Yu | E-mail: mystone@{sol,caen}.engin.umich.edu University of Michigan | Real-mail: Dean Yu Computer Aided Engineering Network | 909 Church St ===================================| Apt C "These are MY opinions."

Just on the off chance, are there any magnets near your Mac+? Magnetic fields can distort the image because they deflect the electron beams. Try moving your Mac a foot or so in several directions and see if the problem goes away or moves. -- Robert J Woodhead, Biar Games, Inc. !uunet!biar!trebor | trebor@biar.UUCP ``The worst thing about being a vampire is that you can't go to matinees and save money anymore.''

I have a (somewhat) amusing anecdote about that: During my later high school and early college days, I worked for the Veterans Administration (VA) hospital in a nameless city. Within the Pharmacy service there, they were just starting to automate (you know the government), and their users were, shall we say, "computer illiterates" ;-} Among programming and training, I was also head honcho in charge of "trouble calls" -- those things which strike fear into the heart of every person who deals with non-computer types. One day I received a call from the Pharmacy saying that one of their terminals was broken. So, I loaded up the hand- truck with a brand-new terminal, and was on my way to Pharmacy. After a few nimble twists of a screwdriver, the new terminal was in place and working like a charm. It seemed that their old terminal had taken to displaying only the right side of the screen. I told them that we would have it fixed. After lunch, I received a message to call Pharmacy. I was told that this terminal had started to do the same thing. I told them that I had something to deliver, but that I would stop by to see what could be done. On my way from where I had to go to the Pharmacy, I passed my the NMR (Nuclear Magnetic Resonance) Lab to get to the elevator. It just so happened to be RIGHT OVER THE PHARMACY! I ducked in to see where their machines were located, and, sure enough, it was along the same wall that the terminal was located. The so-called "problem" with the terminal had to do with a very *LARGE* magnetic field right above it. Boy, the government never ceases to amaze me! Someone else (?) best explained it: You see, there's this hierarchical structure known as the VA...
