A year ago the display on my Mac Plus collapsed into a horizontal
beam.  This occurred after a month or so of wobbling, twitching,
jerking, and other annoying visual effects.  It cost me $200.00
to have the offending card replaced.  I don't know the Mac insides;
I believe it was the video power board (?).  After another year, the
display is twitching again;  I assume this means I will be paying
another repair bill imminently.  Can anyone tell me how to avoid this
in the future?  Pertinent details:

    * I am accustomed to leaving the Mac turned on, with the video
      brightness down, for days or weeks at a time.  The user's manual
      states that it's fine to do this.

    * I have not installed a fan.  The Mac is not sold with a fan,
      therefore I expected that I need not purchase one.

    * I have used surge protector since I bought the computer.

Am I to understand that I can expect to spend $200.00 a year if I
continue to use the Mac as advertised?  Should I get in the habit
of turning the computer off?  The serviceman says to get the "Pyro"
screen saver program.  Does that actually give the board a chance
to cool down, or is it no different than turning down the brightness?
Thanks in advance for any suggestions- mail them if this is old hat.
