Ditto
Sonys usually have little discs or discs glued to plastic sticks then
taped to the bell. They do fall off. You should have a pure blank
raster & a R, G or B color only. Put them in place & move around to
find the sweet spot.
If it comes back or cant be cured its usually the shadow mask broke
loose. Very common when the set gets dropped.
BTW when you junk a set save a few magnets.
