One more question:
Is it OK to leave the chassis in and only remove the monitor? Or is the chassis connected to the monitor and I have no choice to remove them separately? Just want to remove only what's necessary. Thanks again.
If the chassis is mounted directly to the frame of the monitor then it a piece of cake.
Unplug the power cord, unplug the video signal connector, un-bolt and remove the whole nine yards. (metal frame, chassis, tube, etc, all in one neat package)
If the chassis is mounted to a wooden shelf of some sorts, then it can be a bit trickier. Still possible to remove all the guts along with the tube, but I would recommend some help from a friend to handle all the loose dangling pieces. (the chassis board mainly)
NOT RECOMMENDED TO DO IT THIS WAYBut the main point to note is that you can NOT remove the tube by itself without discharging the high voltage anode. It is a direct link between the tube and the chassis. So in order to remove either one seperately, you will HAVE to discharge the monitor.
