Re: Component Video Y, Pr, PB

Whenever I've run across such a situation it's normally a format issue, the 
monitor only supports interlace or it only supports progressive.  The 
voltage levals are pretty much ubiquitous.  The Y channel carries all 
luminance and sync information and should be virtually identical to a 
standard composite output (in 480i mode at-least).  You may have a 
situation where the output parameters in the older player has drifted out 
of spec over a period of time.  One monitor may be less sensitive to the 
out of spec condition than the other.  Such a problem is normally a 
frequency or sync drift rather than a voltage issue.  Anything's possible, 
though, and this is all purely speculation on my part.  Personally I'd 
recommend the customer dump the older DVD player in lieu of a newer unit 
that works with the display.  DVD players (even good ones) are throw away 
cheap these days anyhow.
