[comp.sys.amiga.hardware] Shaky screen on 3000 power-up.

Hello,

     I noticed something the other day.  I run a BBS on my 3000.  I have had
my 3000 running practically since I got it.  I have had no troubles with
it since I had the motherboard replaced (that's another story).  Anyway, 
I had the machine off for about a day and a half a few days ago.  I noticed
that when I turned the machine on I got some shaking of random places on 
the screen.  It's really hard to describe.  It isn't the monitor.  When I 
turn the monitor on after about a day and a half this doesn't happen (while
the 3000 is on).  Only when the machine has been off and turned back on for 
a longer period than 24 hours.  This shaking only lasts for about a minute 
or so until the 3000 gets warm.  

     My questions are...Is this something to worry about?  Should this be 
happening?  Most importantly, should this be serviced?  Thanks in advance
for any advice, help, info.....

	Sounds like your display enhancer is just slightly out of 
	adjustment when the 3000 is cold...  It may only take a
	slight twist of the adjustment screw to get it so that it
	functions properly at both cold and warmed-up states...

	Good Luck!
