[net.micro.mac] brightness problem

rfl@oddjob.UUCP (Bob Loewenstein) (07/21/86)

I have a Mac that has developed a brightness problem.  The brightness 
pot on the front of the case varies the brightness from bright to a 
washed out image. Adjusting the pot on the analog board has no effect.
However, an ohm-meter shows that the internal pot still varies
the resistance in the MegOhm range. The mac worked ok before the heat
spell here in the midwest.  Anybody have any ideas or a circuit diagram 
that might help?
