Ps3 plays in black and white with av composite cable

Some newer TVs do not have the traditional "yellow" video input, known as an "AV" connection. Even without that input, you should be able to use the standard three-color Wii AV Cable that came with the system.

What to Do:

  1. Look for "component" inputs on your TV. These connections have a row of five differently-colored inputs (green, blue, and red for video, white and red for audio). If you have more than one set of component inputs, it's the first set that generally works with standard AV cables. Look for a set that has a green input with yellow around it, or the word "video" just above or below it.
  2. Plug the yellow end of the Wii A/V cable into this green "Y" input. Plug the white end into the audio "L" and the red into the audio "R." Leave the blue and second red holes open.
  3. composite_inputs_window.png
  4. Turn on your Wii console and set your television to the input select being used.
  5. If you are seeing the image from the Wii in black and white, try the following to get the image in color:
    • Cycle through your television's input channels (usually with the "Input Select" or "Source" button on your TV's remote control) to find the input select that has the image in color.
    • If you're only finding the image in black and white, you may need to switch the setting of the input select from a component signal to a standard AV signal. This can be done by:
      • An on screen menu option. This is often accessed by using the "Menu" button on the remote.
      • A button on the remote that switches between the standard and component signals. These can be labeled such things as "AV" or "Video."

Images have some ghosting, but convergence lines seem to be OK. For example, white images have a yellow shadow to the right of image. Any suggestion?

Some easy steps to determine where and what your problem is:

1) In customer menu select convergence and then advanced (done with the Mitsubishi remote) look to see if grid of lines straight and if "yellow" is seen there.

2) Look to see if it happens when DVD etc played; If only on component from a cable or sat box but not on tuner or DVD inputs it is not the set.

3) Go to a channel that is in black and white and in customer menu turn COLOR all the way down: is problem still there or not?

If problem is not convergence and is present on all inputs it will be a problem with one of the three CRT boards; they plug onto bottom of each of the the three picture tubes this set uses; yellow suggests a problem with the blue one______loss of blue may give you a yellow smear around things/ red and green equal yellow.

You do not need to take the set apart for this.

Let me know what you find, the more you rule out the easier it is to know where the problem is.

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Yellow area on screen

either burn in or magnetic field interference. I suggest moving any speakers away from the tv. if thats not the case, then find a strong magnet, make sweeping motions across the screen with it but dont touch the screen! Keep doing this until the colors change, then "sweep" them with the magnet into a corner and they will mostly dissapea.......r, sounds complicated but worked for me. can be scary so dont try unless sickly despearate or confident.   Hope This helps!

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left and fuzzy images this is a symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

Image retention

most manufactures say not to have a still image on the screen for more than 15% of your viewing time. to fix this you will have to replace the optical assy. i did come across a sony projection where the burn in was actually on the screens themselves. the only thing you can try is to put an all white video pattern on your tv for at least 48 hrs.
