Re: IIc keeps tripping the circuit breaker

Hi Tom,

If the capacitor has gone bad, won't it take out the fuse first,
before tripping the breaker?  

Anyways, I opened up the monitor for the first time in my life and I
have to say, Apple did a great job designing the it.  Just 7 screws
and 2 panels later, and I get to have a good look-see.  And it looks
like there are quite a few capacitors to replace. sigh.
