Question about Sony KP-51WS520 51" Rear Projection HDTV-Ready Television

1 Answer

Picture is distorted

The TV works, however the picture started to resemble a lava lamp! There was a blue hue that started to appear at the top of the screen, and now has enveloped the entire screen with a yellow hue, and has distorted the entire picture! What is the component needed to fix this, and is it an easy, inexpensive fix for a 6 year old TV!

My Samsung HLP-4667W DLP TV has no picture when I turn it on.


The color wheel can be ruled out by looking at it---it faces the lamp and can be seen---look to see if any segments of the wheel are missing or if the wheel is totally shattered.

Other than the wheel I am concerned by "blue splotches etc" as it might be a DMD gone bad. Look at the attached photo and the color wheel first.

Both the picture and sound work when the TV is turned on, yet the picture is distorted like a double picture and has a yellow hue to it.


Sounds like you have a convergence problem. If you go into the setup menu of your TV, there should be some settings to adjust the red, green and blue hues and re-position them so each color matches up. If this does not work or if you don't have a menu, your TV *might* have a circuit board with several plastic screws on it. These adjust the picture and it's a very tedious task to re-align each hue correctly.

My projection TV is an older model from 1995, which is probably why it has this circuit board in place of a convergence menu built into the TV.

If adjusting the convergence still doesn't work, you might need to purchase a new convergence chip.

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. 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!

Sony KP-53HS30 Projection TV has pink and blue hue w/timer blink


Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference.
If your TV has a Color Temp setting, you will normally have the following options to select from:
  • Cool: Gives the picture a cooler, slightly bluish appearance.
  • Neutral: Gives the picture a neutral, more natural look and appearance.
  • Warm: Gives the picture a warmer, slightly reddish appearance.
If your TV has a Hue setting, follow the appropriate step below to make adjustments:
  1. Move the setting to the right to reduce the reddish appearance.
  2. Move the setting to the left to reduce the greenish appearance.

3LCD Projection TV 2.5 years old displaying blue hue/blobs


I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.

DLP Colors Are Off - Picture Is Mostly Blue and Yellow


Sounds like you've lost your red video signal (chroma) somewhere along the line. This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. The analog has all your inputs on it, except DVI and RGB which go straight into the digital board. The digital scales (upconverts) the signal to HD (1080 or native) and sends it to the DMD or light engine. See which inputs are distorted. If only DVI is clean then you problem is the analog board. If you menu and everything is distorted then suspect the DMD board. If you run component or DVI through the resolutions (480i, 480p, 720p, 1080i) you can get an idea between the digital board and dmd. The menu is generated on the digital board. Somewhere red is getting lost.
