It will probably be the polarized filters, it will get worse over time

I've noticed a dark patch in the lower right corner of the screen. Is this a bad panel or backlight? It's mostly visible in scenes containing blues.


Sounds like a backlight is out probably due to a bad inverter board. If you can see the spot when the tv is off its probably a bad lcd panel.

Sony wega kdf55 has blue spot in lower right corner - how do I fix


Hi,
That is a symptom of the light engine failing. that is the projector part of your TV where the lamp plugs in. Go to Sony's website to contact them and see if your model is still under extended warranty, if so they will help set up repair. If not it could cost several hundred dollars just for the engine plus labor. Good luck

Blue triangle growing on lower right side


He is most likely right--a burnt light engine will cause problems like this and is very expensive to replace--the set uses a hot lamp for brightness and it sometimes burns one of the optical lens in the engine--blue,red or green. Google the model number and you will see how much the part by itself costs.
Sorry, Steve

Blue spot


the model number KP-51WS510 deosnt use a bulb or lamp. and touching the face of the lamp will not cause color problems in the picture. if your tv is an LCD projection then i would suspect the optical engine as the culprit. to check when you turn the tv off do you still see the blue distortion? if so then you have a bad optical engine.......as long as it is an LCD projection.
