It sounds like you have a 'blooming' problem. Blooming is caused by insufficient high voltage to the anode of your
CRT. The low high voltage allows the beam of electrons to spread too
wide and thus create a picture larger then the screen, to the point
that the screen appears to "bloom" especially on bright or white screen
scenes. The cause of the low high voltage can be the horizontal output
transistor, the damper diode, the safety capacitor, the flyback
transformer, and any of the associative circuitry of these sections of
the TV. I advise that you have a qualified TV repair technician examine
and repair this TV.
