SOURCE: blue dots on my lcdtv
Sometimes the voltage can be set to high by the factory. Throughout time, blue dots will appear. You will have to remove the back cover off the tv, find the "voltage Screws (they are labeled) and turn down (left) JUST A Notch. Have seen this done many times.
Pray that the panel isn't blown out or bad projector tubes. They are expensive.
Blue dots and screen flicker are VERY common on the newer LCD and Plasmas
Also, if you have a pixel setting on your TV (not sure if that one has it) Try setting it to 480p.

It's most likely a capacitor. Open up your television, and look at your power circuit board. Look to see if any of the capacitors are blown.(the will be bulging look up an image of a blown capacitor to get a better image if not known already. Mine was (CS19, CS21, CS22, CS23) Also on (C672) from the Circuit Board.Can you look at the voltages of these for me? I'm missing the capacitors.
