To attain the high level of clarity of characters on the screen a micro-mesh is fitted over the face of the CRT. As the years go by this micro-mesh becomes clogged with dirt and impairs the clarity of the characters displayed on the screen. Unless your screen has been cleaned recently you are not seeing the full capabilities of the monitor. Do not wipe the micro-mesh with a cloth or any other type of material or spray it with any of the glass cleaners on the market today. This will result in clogging the micro-mesh and rendering the view screen impossible to read and may damage the micro-screen beyond repair.

The only way to really clean the screen without damage is to dismantle the monitor to remove the micro-mesh as detailed below.

Read the warning label attached to the CRT. Any doubts do not attempt the procedure but ask a competent person to do it for you using this guide.

Tools need for this job is a crosshead screwdriver, a container for the removed screws and a firm work surface such as a bench or stout table. Optional tools are a soft paint brush and vacuum cleaner.

Placing the monitor on its face and with the base of the monitor towards you remove the two screws that secure the top and base sections.
Gently push the top case section away from you to seperate the two sections and lift off the casing. Turn the monitor back on its base with the screen facing away from you.

	You should now see the metal shroud that encases the CRT and electronic circuits. If at this point you need to remove dust etc from around the shroud a vacuum cleaner is the tool for the job whilst using a soft paint brush to remove stubborn bits.
Loosen the four screws (indicated) that secure the monitor face to the casing. Very gently slide the CRT and electronics housing away from the face. You should now be able to remove the micro mesh that fits to the face of the CRT.
	To clean the micro-mesh immerse in a bowl of warm soapy water to remove any trapped dirt. Take extreme care not to damage the micro-mesh by bending, twisting, rubbing or scrubbing. Only hold it by the edges and not the micro-mesh itself. Rinse the micro-mesh under running water to remove any soap etc. and dry off using a hairdrier set to a low temperature.
Gently clean the CRT with a proprietary glass cleaner to remove any adhering dirt and grime. Be careful where you spray any cleaner as you do not want any cleaner to penetrate the CRT housing.
	Should you want to clean out the area that houses the CRT and electronic panels remove the three screws (indicated) that secure the top part of the shroud. Pull the shroud section towards you and lift it off.
Using your vacuum cleaner and soft paint brush remove any dust etc. from this compartment. Take care not to disturb the wiring or damage the output board and parts. Warning Use extreme care when working in this area. Refer to the warning at the top of this page if in doubt. Do not touch the red wire or the gray anode cap attached to the tube. There is a risk of severe electric shock.

To re-assemble the monitor is the reverse of the above procedures. Be sure to align the micro-screen as it was originally and use the correct screws in the correct positions. Do not force any parts into place.
