Colorful Dots I'll get right to the point. After my Sony plasma is on for about an hour I start to get colorful pixel dots appearing on the screen. They go away after having the plasma powered down for about an hour or two. But they do come back. It almost appears to me like static on old t.v. sets, but the dots are colorful and only appear in small portions. Called the repairman and he scratched his head and said he will get back to me....four months later here I am. Please help, I live in a small community with limited help.

I'm willing to bet that a vid cable is either bad or incorrectly positioned on the display. If the unit is under warranty DO NOT open it and attempt a repair. Take it in for service to an authorized Sony repair facility.

There is a tuner problem or there is a power supply problem. Unless you have extensive plasma TV repair experience, or the shop you call has Plasma TV repair experience, this should ONLY be serviced by an Authorized and trained Sony service tech. You should contact Sony service and see where the closest authorized servicer is located and call them. In your instruction book is the numbers to contact Sony. Good Luck

Check the connection of the cable comming from the cable box to your tv either it is not connected proper or the wire that connects it is faulty and needs the be replaced.if that does not work let the repair man check the IF circuit, video amp and the tunner.it they could be causing the static.good luck my friend.

I have dots slowly starting to appear on my wd-73735. I bought the tv in February 2009 and the light engine had to be replaced once in September of last year. now what do I do?

These dots are called pixels and if they are a certain color, they are stuck. If they are black, they are dead. You can't do anything about to fix the dots neither the service without the replacement of the display (screen)

Dots on screen

The snowy dots and dots are typically from a poor signal going into the TV.

If there are colored pixels that stay lit all the time (like a red pixel and never goes away) and for any input, that’s called a stuck pixel.

A stuck pixel may be caused by a bad Y-Sustain, Y-drives, Z-sustain, and or a bad plasma panel.

Good Luck.

White dots on screen

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 screen. 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!

Why are blue dots appearing on my Sony Flat screen tv. they seem to multiply every day.

If the dots are tiny, those are probably dead pixels. The circuitry that drives them is probably degrading over time for some reason. It's obviously defective, dead pixels happens a lot with LCD screens. I would hope it would be covered by warranty, because the only way to fix dead pixels is replacing the screen.

Sony a100 distortion dots - Im getting several

If these are single pixels on the LCD screen, they are normal. From pg. 8 of the user's guide:

"The LCD monitor is manufactured using extremely high-precision technology so over 99.99% of the pixels are operational for effective use. However, there may be some tiny black points and/or bright points (white, red, blue or green in color) that constantly appear on the LCD monitor. These points are normal in the manufacturing process and do not affect the images in any way. "

This may also be helpful.

"images may trail across the LCD monitor in a cold location. This is not a malfunction. When turning on the camera in a cold location, the LCD monitor may become temporarily dark. "

Blue dots on my lcdtv

Sometimes the voltage can be set to high by the factory. Throughout time, blue dots will appear. You will have to remove the back cover off the tv, find the "voltage Screws (they are labeled) and turn down (left) JUST A Notch. Have seen this done many times.

Pray that the panel isn't blown out or bad projector tubes. They are expensive.

Blue dots and screen flicker are VERY common on the newer LCD and Plasmas

Also, if you have a pixel setting on your TV (not sure if that one has it) Try setting it to 480p.
