    First boot went into BIOS as per normal. When I opened "integrated peripherals" the system locked totally, no keyboard inputs could un-freeze the BIOS page. I rebooted, now I got a black screen, no beeps, the DVD drive's lights flash as in a normal boot then go off, HDD light on continually but they aren't reading, CPU heat sink is cold indicating no activity. Changing video cards, monitors, resetting BIOS, removing battery, refitting all memory and the CPU did nothing.

Hi, check the cable from your computer tto monitor, then check that the video card is installed properly.
If these fail your video card is most likely dead and need to be replaced.

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."

System dead


Hi Fr.David
You mention '..info on BIOS..'
Is your BIOS (or anything) displaying on the screen?
If screen is also dead, then your PSU 5V (red) section is suspect.
As the fans are fanning then 12V DC (yellow) is still OK.
To check your PSU, unplug & disconnect all power connector cables (note where they go, esp the M/Board supply).
Some PSU's have a green 'signal good' wire which to test must be grounded with a paper-clip etc to black.
This tells the Power Supply Unit to start up.
Black is common negative, Yellow 12V positive, Red 5V positive.
I'm positive.
I hope your test results are not too negative. ;)
Hope this helps.
Clive.

How can i play ps2 on lcd without having a black and white screen ? how can i connect the cables ?.....when i look at the back of my lcd i find three ports (red white yellow) when i use them the screen is...


1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

Bright Blue and Green screens seem to blink.


Do not use component video. Test S video or 3 rca's red black and yellow(video) , see if they work! you need all 3 inputs on component video, sounds like you may have the colors mixed, check all color coding slowly. Sometimes the comp video out can be too strong, try using a splitter , reduces signal by 3 db, try 2 then 3 in line. This is only a test. keep in touch...
