The spots are from dust in the optical assy. It would need to be replaced because the only way to fix the part would be to disasemble it in a dust free room.

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

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
