CRT TV HV RED WIRE

[amcwill417]

I amd attempting to remove the chassis from my old TV. I can unplug all
wires except one. This is the high voltage heavy insulated red wire running
from the HV transformer to the back of the cathode ray tube where the is a
large round rubber insulator. I do not seem to be able to pop off either
end of the wire. At which end should I attempt to remove it without
damaging the set?

After discharging the residual high voltage stored on the picture tube
by taking the hv connection to dag ground, simply lifting up the rubber
boot and pressing in on each side of the metal connector clip will
allow it to be removed off the tube.

Thanks. I got it off. This will be the 4th time over the past dozen years
that I have resoldered components on this 32 " Sony TV. I am having doubts
whether I can fix it this time - let alone get all the plugs back where they
belong. But I will try.

Once you begin to troubleshoot the set, post your findings and maybe
someone here can help you out with some repair tips or advice.

All or most of those plugs should be different sizes and colors.
Usually the color of the plug matches the color of the jack, and the
size is always an exact fit. If it doesn't plug in easy enough, don't
force it - it may be backwards. In some sets the plugs have a letter or
number code printed on the side with a matching code on the boards near
the jacks. I anything is not marked you should use masking tape or
little white stickers to make labels so you can find where each plug
came from.
Good Luck.

Well, my repair solder job did not cure the problem and may have introduced
an additional problem. There is now a predominance of green in the picture
so human faces look green which cannot be eliminated by varying the hue. So
I now have two problems. The picture still looks good, however. Thanks for
the tips.

My guess is you either made a solder bridge somewhere, or you swapped
two plugs when putting it back together. Keep at it, you'll fix it
eventually, just be careful.
