Since im being a little lazy while i wait for the LED kit for the monitor, ill just put up all the photos i took during the process of dissasembly which alone kind of illustrate what you need to do. Ill work on more detailed entries and tips over time.

For now though ill just mention that when prying the screen apart, the safest place to do this is on the actual threaded nut part of the top and bottom of the screen on the sides as you can see in the photos.

In the photos of the LCD side of the monitor once separated you can see them, sorry i dont know what they are called.  Each will slip back into its hole on the backplate if you cant get them pressed up against the backplate just above the hole, and unfortunately it has to be done one at a time. Its realy quick and easy though once you just lever off them through the screw hole, all you have to do is stick a little screwdriver in there and pull back on the plate a little and there, done. There is allot of tension and friction holding things in place, you cant just pull the screen apart after that, you need to lever it apart , pretty much at each screw point.

 

Another note worth mentioning is that you dont need to preserve the black tape, for one, it is fragile and the sticky part does not reapply. I think its purpose is to just to keep dust out and away from the high voltage tubes which might attract dust and create a fire hazard.
The tape offers no structural support at all much as it looks like it does, the screen is held together PLENTY, if not to an excess.

Replace the tape with kaptom or a nice ductape.

If your putting in an LED kit like i am, you can even be a little lax on the tape since the LEDs are only 12v or 24v. for simplicity sake just run a knife through all the tape and have it over and done with.

If you intend to replace the tubes however, they do not seem to come apart, basically, you have the 3 tubes on the top and bottom bundled together, silicone potted together with the leads most likely soldered on. replacing any one or more tubes requires destroying the rubber/silicone holding them together, although, with patience i think you can easily re-cast something functionally the same with normal pure caulking silicone which is equally electrically insulative.

the specs on the tubes are 2.5mm x 550mm each with no markings.

Also the insulation wires appear to be TV-3 grade silicone rubber rated at 3KV DC for the presumably negative or ground leads and 3KV AC for the HV positive/live/in. It looks as though the high voltage leads might be under rated or running close to their limits. If you replace the tubes i recommend replacing the wires as well.

 

Everything else is going to be pretty self explanatory, just undoing screws and pulling parts its pretty simple.
