Repair the degauss circuit first. If you have not played with the magnetic
rings around the base of the yoke this should take care of the symptom.
If the tube is a bonded yoke design, witch a lot of Thomson products do
use, you will be unable to adjust anything regarding purity or convergence
on the set. Bonded yoke sets have he magnetic rings glued at the factory and
can not be realigned without major pain involved.
Make absolutely there is no magnetic sources near the television including
external speakers, electric motors, etc that can influence the purity. The
thermistor should look like a small silver or black disk with two leads
soldered to it's sides. Over time the leads can fall off or the thermistor
just simply fail. Follow all the safety related requirements before going
into the set, including making absolutely sure it is unplugged before
removing the back panel.

Did the magnets move by themselves, change the Thermistor.
