Question about Sony KP-57WS500 57" Rear Projection Television
More typically, these color uniformity problems occur without respect
to which input or cable is used. The one exception is when a bad
component cable or component cable connection disturbs the color.
If you're only getting the problem when viewing through the set-top box and HDMI cable, you may try changing the cable, having the box inspected or replaced or tweaking the many XBR1 custom color settings for that specific input.
If you are experiencing a genuine color uniformity issue such as the green haze problem regardless of input after allowing the set a reasonable amount of time for warmup, you may not be able to get it fixed to your satisfaction. Sony's "cure" in most cases has been to replace the optical block. Last I heard, this major component was on back order.They're going to want to do a service call on your set first, of course. If they look at your set and tell you it needs a new OB, I wouldn't waste time being put on a waiting list for the new part. That may never happen, or at least not in a reasonable timeframe. OB replacements don't always go smoothly either; it's a major repair requiring good technician skills. Best bet: go for the XBR2 swap, as a few others have done.
