First thing to check is the 200V filter cap. Its one of the most common
problems on all brands of TV's. It will cause the symptoms.
First go to CRT socket & find the 3 larger resistors all the same value.
One end of all 3 tie to the 200V follow this back to the chassis, it
may go through a choke or low value resistor on the way. You will
come to a diode thats off a FBT winding. The cap is off the cathode of
the diode. Typical value is 4.7mfd 250V, Use at least a 350V.
