Overdeflection or blooming of the picture is usually cause by failures in the flyback transformer which causes reduced high voltage.


E-Prom Adjustments - Service Menu Operation

Unplug tv press menu while applying power. Volume adjust values, channel changes menu. Press menu when done.

Just in case you need to any adjustments after you make repairs.
