Is this a symptom that my TV needs degaussing?

[Pyrrhic]

I have a 68cm Blaupunkt that's about 10 years old, and lately
there's a patch of screen (top left) that's purplish - it's faint but it's
there. I've been moving a lot of gear around in my living room in the last
few weeks due to new carpets going down, and there's a large speaker to the
side of the TV cabinet I've had to shift and replace a few times. The
speaker cones themselves are very large and heavy so would have a fair
magnetic field to maybe affect the TV - do you think the patch on the TV
that's recently come up could be removed by degaussing the screen? Or does
the patch mean my TV (only had it six months) is on the way to the tip? I
know TVs don't last forever and a decade is a big slice of a TV's life, but
it's a great set otherwise and is in great condition (teletext/stereo etc).

Cheers

Very likely. Particularly as its showed up after moving things around.

Very rare for TVs to fail like that. Its almost always an external
field thats the problem, occasionally the internal auto degausser
on turnon has had the thermistor fail, but thats not as likely given
that the problem showed up with moving stuff around. Its possible
its been dead for a while tho and you've only seen the effect of
that when you moved the speakers around. You should be able
to have that fixed cheaply, or just use an external degausser.

Certainly worth getting it degaussed or even the thermistor replaced.
It may not have died tho, it may not have ever had that much
degaussing power and cant handle what those speakers produce.

The Commodor 1701 monitors are absolutely notorious
for that effect. Its no big deal when they are used as
TV monitors coz you really only notice it on the blue
screen when the VCR blanks the output etc.
