If this is a projection TV set, it is possible that there is some dirt in the lens system. If the dot is pink, it is most likely the dirt is in the path of the green. In projection tube sets, it is also possible to have a burn spot on the phosphor of a tube.

If your set is a direct view set such as a liquid crystal, or a plasma, or a flat panel, this can also mean a dead pixel on the green. Dead pixels cannot be revived.

Depending on the particular nature of the fault, you will need an experienced TV service tech to service your set.

I have a 60 inch tv and i have white dots on the screen


that is what we call dead pixel, you can remove this by following the steps below.
  1. Turn off your tv.
  2. Get yourself a damp cloth, so that you don't scratch your screen.
  3. Apply pressure to the area where the dead pixel is. Do not put pressure anywhere else, as this may make more dead pixels.
  4. While applying pressure, turn on your tv screen.
  5. Remove pressure and the dead pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through which give off different colours.
    Hope this helps.

My five year old Toshiba 57H84 rear projection TV has a pink tinted screen when you first turn it on, then after it warms up, the colors are all fine but then the picture has evenly spaced blue tinted...


Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Everything that is supposed to be black is showing


Hi,It sounds like a problem with the color wheel or DMD board. The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will hear ,humming,buzzing,high pitch noises ,you might also experiment color distortion ,black and white picture. This is how the DMD works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.

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.

Blue dots on screen


Not knowing what type of TV you have dosen't help, but if it is LCD or plasma, the problem is pixel failure. There is no repair, only replacement

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.
