Do you have a old CRT monitor lying around your house but you think it's too dangerous.
Now is your chance to do it moderately safely do it.


I take no responsibility for any injuries ect. caused by you disassembling a CRT monitor.

Step 1: Tools

  • Screwdriver (Insulated handle)(one that you don't mind the tip getting a bit melted)
  • Piece of wire, one that you don't mind melting, preferably a thick wire (to ground the screwdriver)
  • Nail (to puncture the tube to fill the vacuum)
  • Rubber shoes (To insulate you from the ground)(optional)

Step 2: Removing the Screws From the Monitor

Well do what the title says,
Remove the screws and you can remove the base if you want to.
When all the screws are removed carefully take the cover off.

Step 3: Discharge the CRT

Connect the wire that was in the tools list to a ground wire,how to find a earth/ground, on that PCB find the earth terminal of the power input and connect the wire to that. Connect the other end to the insulated screwdriver. Make sure that electricity can flow from the end of the screwdriver to the ground wire.

Put the end of the screwdriver under the suction cap and tap it onto the wire. If it is charged you will hear a loud crack, do that a couple of time just to be sure it doesn't crack it's uncharged but try to discharge it a couple of times anyway.

Step 4: Remove the PCB on the Neck of the Monitor

Remove the PCB on the neck of the monitor, there will be zip-ties holding it down or glue. Cut the zip-ties or break through the glue.

You will have to be careful with both methods.

Step 5: Releasing the Vacuum of the CRT

Get the nail or small object to break the point where they originally removed the air (vacuumed) from the CRT.

If you want to be extra careful, but a blanket over the monitor and break the fill point.

Tap the nail in with whatever you want, when you hear it start hissing that means you broke the vacuum, once the hissing has stopped you can do whatever you want with the parts.
