I have a son KF-50WE610 LCD tv. It has developed these small blue dots on the screen. Any idea as to how to fix the problem.

If the dots are irregular in shape or somewhat round, that's dust on the optics INSIDE the projector and you would have to remove the projector, open it and clean the optics. Trying to clean from the outside is pointless and won't do anything.

If however, the dots are clearly defined by the "screen door" grid of the LCD panels, then that is failed pixels and the only fix is to have it repaired.

What do you mean by the "screen Door" grid of the LCD panels? Also how do you remove the projector to clean it?

There are hundreds of thousands of pixels in a digital image. If you look closely at the image, you can see the lines between the pixels. That is commonly referred to as the "screen door effect" because it can look like you're looking through a window or door screen.

How do you remove the projector? I can't tell you, I've not taken one of those projection tvs apart. But if the problem is dust, the projector will have to come and partially disassembled to clean the INTERNAL optics. But if it's bad pixels, there is nothing you can do. That's a failure in the panel(s).
