Matt, it might be possible that the shadow mask in the tube is out of
position which degausing will not repair. If this is what has happened,
try taking a few small magnets and place them around the bell of the
tube in positions where they help correct the blotch. If the magnets
help, I would contact the customer and advise them that you had to do
this because usually it is not a perfect fix. Sometimes depending on
which direction they face their TV set, the blotch can somewhat come
back, usually not as bad but noticable. I have even asked customers
which direction they face their set and then I aim the set the same
direction to place the magnets.
