I'm trying to disconnect CRT from main circuit board on my 27" Sony
Trinston? I did disconnect all the wires except the Anode Connection
wire (red color). I tried to pull out from the power source on main
circuit board, not from CRT. It just did not come out.
What do I have to do? Is this wire a clipped or not?

It should be a wire or pressed steel sprung clip, which fits into what is
called a 'cavity connector' on the CRT bowl. For most CRTs, removal requires
that the edge of the 'poppy' is gently lifted from the bowl, until you can
see the actual metal contact, and then by pressing on one side of the
contact, with the tip of a thin screwdriver shaft, until it bends in enough
to relase on one side. The other side can then just be lifted out.
BEWARE. Much lightning lingers in that cavity connector, and can do for a
very long time after the TV was last powered. Do take care lest this
lingering lightning smites thee ...

Thanks for rebut this but..
I don't wanna pull it out from CRT bowl. The other side was not
coming out last time I tried to lift up hard. It just did not come
out. Well I tried again...

That's your only option. THat is the way it is meant to come out.

You are doing something wrong... <g> Go back and *look* carefully at
the connector at the tube. This is not rocket science, you'll figure
it out. Trying to 'disconnect' at the other end will only break it.
