Can anyone help i have a three year old sony kp-46wt520 rear projection tv.. last week the tv started to loose its green colour now the picture is still great but the football pitch is more bluer than green......a local tv man came out and said its the mother board and cost would be about$1000........... he new this by just turning it on and changing channels it did take him 30 seconds for his expert view...is there anything i can try before i bin the tv as i will not be paying that much for it to be fixed.
That's good news.. your display shows green which meens your green crt is working so the only other way to tackle this is in the service menu -your drives and cutoff's. you get there by starting with a set in standby next using the remote press buttons 1 after the other "display"- "5" "volume+" -"power"
the set will come on and you should see green writing top left. again using the remote...you need to scroll through the long list of settings pressing button "1" as in channel button 1 to advance the list use button 4 to decrease when you arrive at g cutoff you can use the 3 button or the 6 button to get the color you want also try the g drive again using the 1+4 buttons to get there and the 3+6 buttons to adjust once you have the right color write it into memory pressing in sequence "muting " then "enter"
you will see the display color change if you are doing it right, then you can power down the set and turn it back on again to see your resulting adjustment changes, repeat proceedure if needed.
don't adjust what you don't know about save yourself some grief

Sure turn up your screen control for that color slowly if color comes back then the adjustor is just dirty (no repairable) make sure you don't see milky white lines or a solid color on a blank input.
put the unit on a video position that has no source so the tv displays the input label but nothing else.
slowly adjust the screen control( behind the front grille little black box with 6 little knobs on it)
untill you start to see the coresponding color then back it off till the color is gone, you are done.
if this doesn't work then check your video path from jungle to crt output, your output chip may ne fried
