An Acorn Electron ready for a clean-up.
|
|
First, remove the 4 screws indicated in the base of the unit.
|
|
Next, pivot the top half of the case forward and remove the keyboard
ribbon cable by gripping at its ends and working it off. It will more than
likely be tight.
|
|
Remove the keyboard assembly from the top half of the case by removing
the 5 screws highlighted in this image.
|
|
A view of the keyboard assembly removed.
|
|
Remove the keys one at a time by gripping hold of them and pulling
upwards. Some will come off easily but some will take quite a force.
|
|
Dust, then wipe the keyboard chassis with a damp cloth. Then take
a damp cloth to the keys. Not the best of images but you can see the difference.
|
|
Once cleaned, all the keys can be refitted to the keyboard's "chassis".
Just press them back on.
|
|
Next, take a wet cloth, drip water on the case and give it a good
scrub with an "old" toothbrush. This will get any grime out of the textured
surface. (Bad image Right Hand side clean in this picture).
|
|
Now remove the Mainboard and internal PSU by removing the screws
an cables highlighted.
|
|
The two boards can now be lifted free. Clean the bottom half of
the case in the same was as the top. Damp cloth and a bit of a scrub with
a brush.
|
|
Dust the PSU board off, then INSPECT the area highlighted in this
image for cracked solder joints.
Its a common fault on Electrons. Repeated removal/insertion of power
lead weakens the joint.
|
|
Clean the mainboard with a brush and vacuum hose and it will come
up like new.
|
|
All the parts laid out ready for re-assembly. Just do the reverse
of above, you cant go wrong.
