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.

My monitor's color is mixed with the color yellow

There is an option on the monitor to reset colour to factory default. Just bring up the on screen menu by pressing the left most button at the botton. Use the button next to this to highlight the colour settings which I think is the 5th or next to last option down. You will then see the option to reset colour and various other factory default settings. Happy computing

Rear projection screen 152cm lg going yellow

I am guessing that this is an LCD projection set, Please post the make and model so I can confirm. In the mean time, if it is an LCD, there are 2 possiblities.

1) The lamp may require changing. Sometimes the inner surface deteriorates because of the heat.
2) The "light engine" requires replacement as the heat and light have started to burn the LCD surface. This burning starts to show up as a yellowing usually onm one side first and spreading to the other side.

you will have a mains lead with an electric kettle type connection on one end which plugs into the rear of the screen and another similar lead for the pc.

the video lead from the screen will plug into a small dovetailed shaped connector coloured blue on the rear of the computer ( it can only fit one way round , as its broader on one side than the other )

the speaker leads will probably be small jack plugs one for left and one for right, and they plug into the rear of the computer, audio out / left / right.
