Sony KP-57WS500 (by 2 users)

If you just bought it 2 months ago, it should be under warranty.  I would
try the warranty bit myself, it might save you a few hundred.  As far as
calibrating a rear projection set yourself, forget it unless you have the
proper equipment and lots of experience.

Press #2 on the remote 11 times to the Option-E O Lamp Time. Note the current value and write it down. Add 2000 to the value (ex if 1356, than 1356+2000= 3356). Divide this number by 100 and write this value to the Option-E 11 P CTL SHT1. For our example above we would have 3356/100= 33.56. So we can round to 34.
Now add 50 to this number. In our example we would have 34+50=84. Write this value to the Option-E 12 P CTL SHT2. Make sure to write the data.
Select AUTO in the menu for the Image Revision setting and exit the menu screen. Confirm that the picture is fine.

There isn't anything you can do to fix it. It is a common problem with a
certain set of Sony TV's. Any consolation you aren't the only one with this
problem. The problems can include flickering in dark scenes, changes in hue
especially green. Depending on where you bought it and if there is any
extended warranty I would try there 1st. I bought mine at Circuit City and
was able to get them to exchange it for a new one even though I had had it
for 4 months. If you can't get it exchanged then go through the warranty
repair process. Definately contact SONY At Your Service customer support. Go
to some of the Sony Forums on the net and you will find a lot more info.
Hope this helps.... Mike... Here's some links...
