It would take a very large lightning hit to magnetize or damage a CRT.
The set would have been destroyed first! I think the screen became
magnetized, and should be able to be demagnetized. But, if he dropped
the set, banged it very hard, or put a very strong magnet to the mask of
the screen, this would do permanent damage to the tube.

After thunder storms sometimes we have seen people try to make
questionable insurance claims for equipment that is defective. This is
something that cannot be indicated openly without proper evidence.
Insurance companies have many claims from people for damages that are
not even relative to the event.

Hello folks- I have an RCA TV chassis # CTC185AB. Customer said
after a severe storm he started getting weird colors on the screen.
Picture is perfect. I checked for blown parts and found none. I
resoldered some joints and replaced the deg. thermister just to be
sure. I also tried to clean these patches of color externally via a
deg. coil. I made some progress but the corners are still messed up.
I'm starting to believe he dropped it. Can storms do so much damage
that the screen can't be completely demagnetized ? What other
solutions are there in this case other than placing magnets on the CRT
? Thanks
