SOURCE: Monitor goes to white at cpu shutdown

The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode. Your monitor looks like it may be in need of repair, contact info: PTI Technologies Inc. 7372 Doig Dr. Garden Grove, Ca 92841 Phone: 714-799-3899 Fax: 714-379-6290 Hours: Mon - Fri 8:00am to 6:00pm PST

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.
