I bought a WD-73727 exactly 1 year and 2 weeks ago. A few days ago I first noticed a problem where the screen flickers and the picture looks greenish. First I thought it was my Directv receiver so I switch to other input sources (DVD and PS3) and they all had the exact same problem. I tried turning the TV off for a few seconds and turned it back on and still had the same problem. I then turned it off for a few minutes then turned it back on and the problem went away. Today the same problem came back and again the turn off for a few minutes then turning it back still works. However, today the problem seems to come back much more frequently. It seems to happen every 15 to 30 minutes which is really bad.
