Colors going bad on my tv?

malcolm_cane

Do you have a DVD player or game player connected to your TV? If so, do you get the same colors for the picture? If you do, then there may be a problem with your TV. If you don't get the same colors for your picture when you play a DVD or a game, then try to replace the cable between the receiver and your TV. I hope this helps.

the colour sensor on the picture display may have lost functioning....as in case of plasma tv`s the they use transistors for colour ......so better call a technician from the related company and do a check up.....no other solutions i hope.....

try connecting thru an hdmi cable from your dvd player to your tv, check the colors then.. I'd say you have crossed your component cables.. match the connector letters a/b/x? and plug them in one after each other.

Yes,the tv have a colors wheel and it is the cause of these problems.Humming noises,motor noises,picture flashes black&white or colors pictures within the pictures.The colors wheel,is dying or already dead.Hire a tv tech. replaced the colors wheel,will solved ur tv problems.

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. 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!

Hitachi was know for their problems with picture tub sets. Every time is was the main the board was bad that was control green gun.

Try replacing your lcd controller. It's the board that actually makes the screen display the picture. Usually you will see the colors getting a little screwy and then the longer you have the tv on the hotter it gets and the worse it gets. I had one that started to look silvery then got worse as it got warmer. For lack of better ways to describe it, it was like you were watching tv on a crazy acid trip. Once you change the controller it should be ok. If that doesn't work 99% chance it's a bad lcd panel. I've seen about 6 of those all with similar issues as you have, they were all brand new tv's and all Sharp Aquos.

You TV missing Green color ratio to produce correct colors in picture. It might needs service and adjustments in Video section .

Sounds like one of your colors are missing. make sure all colors are lit, Blue, Red, Green

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence
