Re: An eMac Flickering/Jittering Screen Mystery

2010-01-12 Thread Elliott Price
I agree with Jason and Christian; it's probably the monitor hardware. I doubt 
it's a software/motherboard issue; I've had a couple of old Apple displays 
exhibit similar symptoms. Like Christian said, monitors just age. If it pops 
back to normal with a slight tap on the side or top of the screen, (well, the 
computer in this case) that's definitely a monitor problem. 
One solution would be:  get an eMac with a bad motherboard and exchange 
components; I would just take the good motherboard/RAM/HD and put them in one 
with a bad motherboard - shouldn't be hard to find, since those ones were known 
for bad motherboards. That would probably be simpler (and safer) then replacing 
the flyback transformer, analog board capacitors, and other components. You 
could post an add on the LEM swap list.

An eMac with bad capicitors should be easier to find than moldy toast.
(i've got 2 in the school's workshop) and it should be easy to drop
your good logic board into a working monitor base, would probably take
no more than 45 minutes (i'll find out soon, we've got a few that were
butchered by some students, so they'll be getting torn apart soon...
real soon)
