It's not that easy to remove if you whant to do it save.
Be aware that the voltage on a picture tube can be as big as 300000V.
This voltage can stay for long time on the tube even when the 220V net connection is removed.

Lets start('Laughing')

**********************
There for you should ofcourse disconnect the 220Volts from the main.

Then look fot a ground wire around the tube. connect a wire to it.

Place a srewdrive in a plastic tube (hard like the one you use for the 220V house instalation lenght 30cm) place you filips srew driver in it at one end
and connect te wire to your srew driver.

Now hold the plastic tube at the other end in your hand and do not touch the wire any more . do not grab the wire and the platic tube in you hand at once.


So you have created now a long srew driver with lots of isolation distance.

You can now push the srew diver under the plastic cap on the picture tube.
Some time you will get a big spark over for m 3cm or so.
make connection with the middel point and triy to release the hook under this plastic hood.

Thanks for the info, but I'm not sure I understand completely.

The TV has been unpluged from the main 120V house power supply for about 40 days. It is a 25 inch GE consol TV and I"m not concerned with saving the tube, I want to recycle the cabnet for other uses.

There is a circut board of some kind on the end of the tube. Where would I touch the screwdriver to discharge the voltage?

So let me get this straight. You're going to take the word of a complete stranger (who may or may not know what he's talking about, and could be some 12 year old from a 3rd world country ) and take his word on how to remove the tube from your TV? Are you aware that even though the power is off you can still get a nasty shock or even electrocuted doing this?
Are you on drugs? I'd like to know so I know which ones to stay away from.
I think you oughta have your head examined

my .02 cents

I agree If you do not knew any thing about electronic /TV don't even try it .

It can be realy dangerous for your helth you can be electrocuted.

It's better for you to dump the tv

Yes, I'm on a program to do away with my addiction to $85 service calls.

Thanks everyone for your help. The job went smoothly and easily.
