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?
