These two messages were returned undeliverable.
I thought I'd post again incase others might find them useful.
Enjoy.
Hello JJ,
You should really try the electronics spray before thinking about
sending your Apex in for repairs.
That would be a lot cheeper and quicker if it fixes it.
Soda is very sticky so it may be causing those dots to not move.
The spray should be able to remove the residue from the soda and
allow the pins too move.
I find that holding the compressed air cann upside down the first
time allows more of the cleaning solution out.  Then spray it
with it rightside up.
You may need to do this a few times because soda is so sticky.
Exercise your display after you clean it and you may even want to
spray it once after while the display is exercising.

Good luck.

Hello Rajmund,
Below is an artical explaining compressed air.
Enjoy.
Sincerely,
John


Canned air comes in a pressurized canister used to clean
sensitive electronic equipment like stereos and computers.  The
contents of the canister are under such extreme pressure that
they have become liquid, but a narrow nozzle directs the released
gas into a strong stream of air.  The air blows out dust and
debris from tiny places like the spaces between keys on a
keyboard.  Since canned air has no moisture, added chemicals, or
foreign particles, it is a safe and efficient method of cleaning
such devices.

Computer technicians, photographers, and stereo enthusiasts have
been using canned air for years to clear out accumulated dust
from delicate areas.  For instance, the insides of computers,
especially around the fan, can build up so much dust that it
begins to interfere with the cooling or functioning of circuitry.
Particles cling to surfaces like lenses, film negatives, and
enlargers but you can't use a cloth or feather-duster lest you
scratch them.  Electrical components can't be sprayed with
anti-dust chemicals because they might damage the circuit or
build up excess static electricity.



Canned air has been specifically designed to clean places that
couldn't be cleaned with a vacuum, dust cloth, or ammonia-based
spray cleaner.  Its contents contain absolutely no moisture, so
it isn't dampening your printer, scanner, camera, eyeglasses,
keyboard, monitor, or hard drive as it cleans.  While it's true
that canned air only sprays the dust back into the air, where it
may resettle, it has an advantage over vacuums since it doesn't
create a static charge.

You might be worried that if the atmosphere gets more polluted,
we'll all be paying to live off of canned air.  However, this
useful product isn't like the air we breathe at all.  It used to
contain chlorofluorocarbons like many pressurized canisters, such
as hairspray.  After those gases were shown to damage the ozone
in the atmosphere, most companies eliminated them from canned
air.  Now, the mixture is often made up of a lot of nitrogen,
along with other harmless gases heavier than air, so that they'll
be labeled "ozone safe."

The non-refillable containers look like small cans of oil
lubricant.  The contents are delivered through a long,
cylindrical nozzle when you depress a valve with your index
finger.  The contents are nonflammable.  It is possible that
enough gas could displace oxygen in one area and cause
lightheadedness, so make sure you work with adequate circulation.
The canisters are no longer allowed on airplanes.

Another interesting aspect of canned air is its adiabatic cooling
property.  When gas is under such high pressure, around 70 psi, a
release of pressure causes a notable drop in temperature.  You
may notice that the surrounding air and the canister itself gets
cold during use.  The rapid expansion of gas that previously
occupied a small space into a large space means that it absorbs a
lot of heat from the area as it spreads out.  For this reason, do
not ever spray canned air onto your skin, as it can quickly cause
frostbite.
