For my Coolscan II, a similar problem happened : blinking led, no
scanner detected.
Cleaning the scanner, by blowing all dust away solved the problem. I
guess the scanner could not
initialize itself anymore.
The design of the internal Coolscan II will always result in lots of
dust...
Later I bought the Coolscan III (ICE is a great feature, saves lots of
retouching).
This scanner could not be completely opened for cleaning because some
tine black screws could
not be removed (even though I had all the proper screw drivers, used
by a professional company!).

Hi Jan and Barry,
Here are excerpts from the procedure, first, on screwdrivers:
1) Set of jewelers screwdrivers, needs both flat bladed and Phillips
tips. As a minimum, a set of 6 from Radio Shack $8-10 (Archer Japan)
will do. A quality set from Felo Cat# 280-907-06 kit of six double hex
shaft tips plus handle with knurled nut clamping chuck (Germany) $40
is better, especially their Phillips #0 size (UPC 4007157-507235).
A separate Wiha brand Cat#261 Phillips #1 screwdriver ($7 Germany) is
also highly recommended for its precision tip that fits screw heads
perfectly, even under high-torque stress and has a 3" long round shaft
and rigid handle for hard-to-reach mechanism screws. The Wiha tip is
machined so precisely that screws seem to stick on the tip without
being magnetic.
May need a medical-type hemostat, forcep or tweezer to pick out
dropped and re-position tiny screws. Available at an unusually
complete Ace hardware store, such as Seven Corners Hardware, St Paul,
Minnesota, (651) 224-4859 7corners.com, with an upstairs nationally-
rated catalog mail-order operation at (800) 328-0457
And secondly, some procedural details on using them:
N) On the bottom of the mechanism, there is a spring-loaded brown
bronze clip / spring covering the Autofocus Z-axis stepper motor
shaft. Using a Felo Phillips #0 screwdriver, remove the tiny screw
only, put in vial #4
It may be screwed-in tight, so use a like-new tip and lots of
persuasive but delicate hammering, pressure and torque on hex-shaft
(like an micro-impact wrench), remove screw but do NOT bung-up the
screw-head, may need assistance here as it can be a two-person job
O) using a small flat-bladed screwdriver, carefully pry-lift slightly
the clip and slide it off the shaft of motor, exposing the slot on the
end of shaft. The shaft is under the front-side of clip between the
visible metal screw ends of the motor mount
P) manually run the Autofocus up and down and lube the four bearings.
There are two short post-type bearings on the bottom of both sides of
the mechanism. And there are two fork type bearings that slide up and
down on the upper X-axis shaft. Also lube the four contact points on
the two leaf springs on bottom that provide return pressure on the
mechanism
It is considered that Teflon lube and manually working it is an
especially important step for the Autofocus mechanism. When moving it
up and down, observe to make it as smooth as possible, although it
will appear to be jerky at the ends of range
