The set may have been dropped, and the mask in the tube was damaged.

The degaussing coil is not working properly.

The CRT was exposed to a strong magnet and requires a proper degaussing.

The deflection yoke, and purity magnets may be out of alignment. This also
means a full convergence alignment.

Because I can see some rings or curved lines (looks like Newton Rings),
from experience when I have seen these, it was usually the mask in the CRT
that was damaged.

Would someone have a look at this TV screen. The fix could be easy but
beyond me right now.
