Technical characteristics of the IBM 8513 monitor

Before we get started with the disassembly and cleaning process, here are some technical specifications of the IBM 8513 monitor:

  • Monitor type: CRT (Cathode Ray Tube)
  • Year of production: late 80s
  • Screen size: 12 inches
  • Resolution: 720x400 pixels in text mode and 640x480 in graphic mode
  • Colors supported: 256 simultaneous colors, selected from a palette of 256000
  • Weight: over 10 kg
  • Power supply: 230 Vac

The IBM 8513 monitor was sold in combination with IBM/2 IBM computers. The specimen I have in the collection dates back to 1987: it was combined with the IBM PS/2 Model 60 computer that I have kept since I was a child.

Necessary equipment

Before you begin, make sure you have the following tools and materials available:

  • Long, thin screwdriver to use as a lever
  • A caliper to unscrew the only closing screw, head -on -headed
  • Plastic lever for body shops
  • Degreaser
  • Soft brush
  • Toothbrush
  • Soft and clean cloths
  • Compressed air

Safety first

Before disassembling the monitor, it is essential to work safely.

Leave the monitor turned off for at least a couple of days, to allow the internal capacitors to discharge completely. Capacitors can maintain a dangerous electrical charge even after the monitor has been turned off.

It is clear that this article is aimed at people who are already electronic practices and know the basics of safety in the electrical field. Those who do not have these skills is better to turn to a technician to avoid damage to themselves and the monitor.

IBM 8513 monitor disassembly procedure, removal of the bottom support

Turn up the monitor to facilitate access to the lower support tabs. They are found in the front of the support.

Press the two front tabs at the same time and remove the support by pushing it towards the rear of the monitor.

Reassembling the lower support Reassemble the lower support by inserting the hooks into the appropriate slots. Slide the stand towards the front of the monitor until it locks into place.

Removal of the closing screw

Identify and unscrew the only closing screw, positioned under the lower support, using the caliper (or a pipe key of appropriate size).

Separation of plastic shells

Locate the two slots at the top back of the monitor.

Insert a screwdriver into the first crack, hooking the internal hook. The screwdriver must be long enough to reach the plastic hook inside the monitor. At the same time, it must be thin enough to enter the cracks without deforming them. In the following photos, you can observe the shape of the hooks for more clarity.

Move the hook from the top of the monitor downwards, levering it with the screwdriver. Do not apply excessive force to avoid breaking the hook!

Use a plastic leverage for bodies to slightly remove the two plastic shells of the monitor. Do not force excessively to avoid breaking the hooks. I know that some people use cutting screwdrivers to leverage and separate plastic shells. I advise against the use of metal tools, because they leave unworthy signs on the plastic parts.

Move the hook from the top of the monitor downwards, levering it with the screwdriver. Do not apply excessive force to avoid breaking the hook! Use a plastic bodywork lever to slightly push the two plastic shells of the monitor apart. Do not force excessively to avoid breaking the hooks.

Repeat the operation with the second crack, up to completely release the plastic shells.

Move the hook from the upper part of the monitor in a lower direction, leveraging with the screwdriver. Do not apply excessive strength so as not to break the hook! Use a plastic leverage for bodies to slightly remove the two plastic shells of the monitor. Do not force excessively to avoid breaking the hooks. Repeat the operation with the second crack, up to completely release the plastic shells.

Removing the back shell

Remove the rear shell of the monitor by pulling it towards the rear, exposing the internal components.

Internal cleaning of the IBM 8513 monitor

Use a soft dry brush to remove dust from internal components.

For harder to reach areas, use a dry toothbrush to brush away the dust.

Only on electronic parts with more stubborn dirt, it is possible to soak the toothbrush with a little alcohol and rub. Wait for the alcohol to dry.

Cleaning of plastics

Apply the degreaser to a sponge and completely moisten the plastic parts. Be careful not to let the degreaser come into contact with the electronic components.

Leave the degreaser to act for a few minutes.

Also clean the VGA cable and connector, taking care not to get the contacts wet.

Rinse with warm water, being very careful not to wet the electronic boards. The rear part of the monitor shell can be easily rinsed under a jet of water, as it has no electronic components.

The front part of the shell should be wiped several times with a cloth moistened with water to remove dirt and excess degreaser.

Dry with soft cloths and complete drying using compressed air.

Wait a full day to ensure all parts are completely dry before reassembling. In particular, there is a sponge at the back of the shell, which is more difficult to dry.

Reassembling the IBM 8513 monitor: replacing the back shell

Pass the VGA cable through its hole and reattach the black cable gland.

Position the rear part of the plastic shell so that it fits perfectly with the front one. Inside the back shell, there are guides for the monitor's electronic board. Make sure the card is in the correct position before closing the monitor.

When inserting the rear shell, if the position of the internal card is correct, there is no need for excessive force. In the following photo you can see the shape of the hooks that are used to hold the two parts of the monitor shell together.

Final results

Here is my IBM 8513 monitor after completing the disassembly and cleaning process! The device looks like new. Thorough cleaning not only improves the aesthetic appearance of the monitor, but also contributes to its correct functioning and longevity, as the accumulation of dust, together with humidity, can become electrically conductive and, moreover, can block the passage of air for cooling.
