Panasonic TV model CT36SX12F blows fuse with degausing coils plugged in.
 
The 6.3 amp fuse was open. I replaced it with a 4.0 amp just for test
purposes. The degaussing coils happened to be unplugged at the time so
that I could get the chassis out for inspection and the set came on
fine. I then plugged the coils in and tried it. There was a loud hum
from the coils and the fuse lit up and opened. It seems that I recall a
certain series of set that had a problem with the degauss thermistors.
Can't remember if it was Panasonic or someone else's though. I haven't
got a 6.3 amp fuse but I'm pretty sure judging by the way the 4.0 amp
lit up the 6.3 would probably not last either. Is anyone familiar with
this problem who can possibly elaborate on it further? Thanks for any
help. Lenny Stein, Barlen Electronics.

The L&R of degauss coils is too low to have much effect, so the problem
must be the series thermistor. If its your own set, leaving the coils
unplugged is a pretty simple solution in most cases.

Lenny ...Replace the Thermistor ( just in case ) and put in a SLOW BLOW
fuse.
That will fix it.

BTW Panasonic does have a bulletin regarding nuisance fuse blowing with
appropriate remedies.

I replaced the thermistor with a new one. It checked out resistance
wise cold just like the old one so maybe the old one was good and the
original fuse just stressed. I put in a slow blow fuse and the set
seems to be OK. Thanks for the assistance. Lenny.
