I used my degaussing coil on the TV again today. This time I moved the
coil over the front, sides and top of the TV. There's still a tiny bit
of green in one corner (you have to look closely on a very light
screen to see it) and my friend is satisfied and didn't want me to try
the bulk eraser.

I'm afraid the degaussing circuit in the TV is not working. The green
spots got worse in the week since I first degaussed the set. My friend
is unwilling to give up her TV now so that I can repair it, but when
she goes on vacation this summer I will repair the set.

Thanks again for all the responses and advice. It's greatly
appreciated.

Just another little bit of friendly advice Ron - don't top-post ! It's
greatly frowned upon in newsgroups, and whilst it's reasonably tolerated on
this group, doing it on some others will cause a shed-load of abuse to fall
onto your head ...

** Now he tells us ......

Did he never guess that the failure of the degaussing circuit CAUSED the
green patches to appear ??

I wonder how someone who would ask these question about degaussing
determine the internal degauss wasn't working?

I had a TV with a failed degaussing system which caused a serious
color blotch as Phil described. This one failed because of a relay
contact flexing the solder joint on the PCB which eventually failed. I
removed all the old solder and re-soldered it. It went 8 years before
the first failure.
