    On the right side of my screen I have a bright dot, it changes colors for the most part and is not noticable when there is a black back lighting. Do you know what it is and how it can be removed.

You have to get a repair guy to come out. When this happened to me the guy changed the bulb (which didn't work) and the actual internal projector (which did work). But he had also said there was a software fix for this problem that is considerably cheaper.

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.

On the screen is a small green dot in the upper right...especially noticeable during dark scenes on shows

There is a software update for that unit but you will need a shop that has the box to do it with. This box is provided to authorized shops. I recomend you find a shop that is a panasonic warranty service center.

PT-50LC13 won't turn on. Will blink green and make a chirp noise

It is the balister not the lamp. Very common problem that Panasonic will not address. Costs over $600 to repair. file a complaint with consumer affairs please.

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.

Red, purple and green dot

Its the light engine. Had a tehnician come and look at mine and was told it would have cost over $600 if I didnt have the warranty. Panasonic called 2 weeks later and told me that parts are no longer available for my model and are upgrading me to a 50 inch tv.(from 44 inch)

Green and Blue spots on screen

Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.
