The blue dots are due to a failing optic block. The lamp is only making them show up more obviously. The TV is probably failing as the blue dots will get larger and eventually take over the screen.

One yellow, one pink, and one blue spots appeared on my tv screen.

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.

That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.

Not fixable.

Yellow, magenta, cyan dots appear on screen

I am not laughing but I would suggest if possible from the rear with a light first to see if any of the bugs are on the mirror at the rear of the set inside or the lens This set should have inside---look for that first---anything on the mirror or between it and the screen will be magnified and projected into the picture----it is possible to take a good photo and post it here as well.

I have seen this once before---had lots of little moving specs on screen of a Sony---they had several hundred knats inside flying around that were attracted to the light and warmth there.

Solution in that case actually involved use of Moth balls for a while in the area.

Blue tints w/ tini blue dots

if you see blue pixel type groups of squares or dots you may have a burnt light engine and this is common in many LCD rear projection sets; a blue screen may mean the engine became burnt--LCD rear projection sets of this kind have an optical enginge--with red,green,blue prizims--sometimes they get burned by the lamp---a photo would tell me or most techs what the problem is---the cost of a replacement engine is very expensive--some models with this problem are covered by Sony even if the set is no longer in warrant

52" RCA Rear Projection P52937SG Color Dots?

There could be an obstruction in the way of the three picture tubes on the inside. This tv has a chassis that comes out from the back all in a chip core frame with handles. Takes a quarter inch nut driver to remove and you should look to see if the speaker wires or the keyboard wires are obstructing the picture tubes. Other something I think of is a broken reflector and when you get the chassis out you can look up inside behind the screen to check for this and for any other obstructions.

Blue dots

You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time
