I have a Sony KP65WS500 rear projection HDTV. For the most part the picture is still clear except for a slight blue wash across the screen. And when there is a dark picture, I can see blue horizontal lines across the screen as well as the significantly bluer wash.
Any help or advise would be appreciated.
Thanks
Dave
Hi,
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.
