Degaussing TV's CRT due to color distortion
Brian
corner of the display. This distortion is due to the magnetic fields
produced by the speaker that was placed beside it. My question is: can
this be corrected by degaussing the CRT? and whats the easiest and
most simplified method of achieving this?

1- Get a weller soldering gun type
2- Approach patch on tube from 2 feet (trigger pressed) and wave the top of
the gun over the spot.
(You will see a interference pattern)
3-Reverse step 2
4-The AC magnetic field from the gun should have don the job

Use a bulk tape eraser. Slowly withdraw the thing while it is powered up
until you stop seeing special effects on the screen. Then turn it off.

and after a week or so should clean up, assuming that the speaker is
removed...
Otherwise if you have a soldering gun, you can use it to do the trick,
just turn it on about three feet(1 meter) from the TV and then move it
very close around the face and side, then remove it back to 1 Meter (3
feet) BEFORE turning the gun off!

it on will cause the internal degauss circuit to activate and clear up
any stray magnetism that is affecting colour purity. This is
especially the case with older TVs that have mechanical on-off
switches, as well as with many more modern remote controlled sets.
The FAQ has more on this.
However, there are some sets with which a simple power on-off routine
will not work, at least not in the usual way. An example is the
RCA/GE TX825/6 chassis. In these 13 inch remote controlled sets
the degauss circuit is directly connected to the power cord connetions
on the main pcb, before the power on-off control circuitry. The only
time the degauss activates in these TVs is after the power plug has
been pulled out for a while.

Also, some of the newer Samsungs have the degauss controlled by the
uP, so they can be unplugged and then plugged back in for an immediate
degauss, even if only on for a few seconds each time.
