Re: Shaky SE/30 screen

[John F. Scipione]

Well, I grew some balls and removed the analog board only to find that 
it appears to be perfectly fine, their is no corrosion, no obviously 
leaky capacitors, no black marks on pins, no ozone smell, no cracked 
solder joints.  Everything looks peachy.  So, I am at a loss as to what 
to do.

The shakes can be a problem associated with components on the analog 
board
or an improperly adjusted power supply. I don't have it in my head but
there's a way to check it with the leads from a voltmeter under load, 
that
is with everything connected, using two pins of the bundle that runs 
from
the analog board to the motherboard.

I think the adjustment for voltage is under the cover of the power 
supply
in amongst the parts.

A replacement analog board from an SE has provided me with good 
results if
the existing one on your SE/30 is too tired to tune.
