How to get a chassis off your
monitor without giving yourself
a nasty boot!
A very simple guide to discharge the
monitor and remove the chassis so
that it can be sent for repair.
By
What you will need…..
Philips Screw
Driver
Alligator Clips
Flat Blade
Screw Driver
Make sure the machine is OFF
and UNPLUGGED
Note that the plug is in
front of the cabinet with
no chance of it being
plugged in without YOU
knowing.
This is a chassis in a cabinet….
Typically, these are mounted
towards the back on the side
of the cabinet as pictured.
This is the back of a monitor in
the cabinet….
Note the copper wire towards the
top. This is called “the yoke”, or
“deflection coil”.
The small PCB attached to the
bottom of the monitor is called the
“Neck Board”.
This is how the chassis will be attached to your
monitor. Chassis and monitor are on the bench
to show you easily how this looks with a camera.
To get your chassis off your monitor and send it to us for repair is
one thing, getting it back on after the repair is another. We would
suggest that if this is your first time at removing a chassis from a
monitor you should mark the connectors like this…..
Mark and remove all
connectors that go to either
the monitor or the cabinet,
DO NOT remove connectors
that go to another part of
the chassis.
This is the tricky part…. Brain must be in gear from this point
onwards. Attach the alligator clip or piece of wire to the earth rail
running around the monitor.
Attach the other end of the alligator
clip to the flat blade screw driver.
Make sure the alligator
clip is clipped onto the
screw driver away from
the handle.
Holding the very end of the screw driver
handle, slide the screw driver under the
suction cap.
Be prepared for a CRACK noise, and maybe even a little flash. Or
maybe you will get nothing at all. Just make sure your screw driver
is touching the little metal connector underneath the suction cap,
and your earth (The alligator clip) is still attached at BOTH ends.
(Both the screw driver and the earth rail around the monitor.)
Remove the suction cap from the
monitor like this….
You will notice when you
lift the suction cup on
one side how it is
clipped under to hold it
on, when you replace the
chassis after repair
make sure it is clipped
back the same way.
Then remove the neck board like
this….
Notice how the fingers
are on both sides of
the neck board. Gently
rock the neck board
back and fourth with a
slight pulling motion.
The neck board will
eventually come off.
Remove the chassis with your
Phillips screw driver….. (generally)
There you have it, ready to pack
and ship for repair.
When you get the chassis back after repair and you go to put the
chassis back in, discharge the monitor again. Some monitors can
build up a small charge even without being turned on.
That’s it, run through the presentation
again, and make sure you are familiar with
what to do.
