52" RCA Rear Projection P52937SG Color Dots?

We bought this tv used and realized there are spots of color magenta blue and yellow very small on the top left right and bottom left. When the tv is on and the image is dark they aren't there otherwise they are. I'm not really sure what it is if it could get worse or be fixed? Any help would be greatly appreciated.

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.

Panasonic PT-61LCX65 tv has color spots

if you mean color spots size of a dime or so.
  • easiest: it is dust in some step of the projection light path.
  • hardest: the light engine could be damage
if you mean little ones as little dots (a neddle punshing) red and blue but always there:
  • condition call it: pixels always on: light engine is the reason.
as you see the light engine is the main part here, IT is expensive repair. so if you can survive with those little dots do it.
IF it is dust, is good idea asking for and estimate to see if can works.

Converge off a little and screen has green tint

If you have the remote, go to the setup screen and move the picture. Converge has nothing to do with where the picture sits but, where the red, blue & green dots land. All you should see are pure white dots. There should be absolutely NO color ghost anywhere on the screen. If so, you need a bar / dot generator to set the convergence to center the dots.

Yellow Spot dead center on screen

most likely the yellow dot is due to a burn in the picture on the "green" lens. It's not removable because it's burned it, but you can try cleaning it because sometimes, dots are caused by dirt. The worst that can occur is that if the dot is permanant.
