Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

This problem has been around for awhile.
The 2HDW PCB needs to be replaced. Part number 935C966001. It sits on the signal board underneath a metal shield.
Not a bad repair and remember to unplug the set if you are going to do it yourself.
Respond to this post if you have any questions and I will reply.
