After much reading on this forum and great advice from everyone I recently purchased a 42WH46 and am relatively happy with it. There are a few problems that perhaps someone on here can help me with (demon if your out there!) There is a staining on the right hand side of the screen, comes in bout 2/3 inches and is leght of bout half the screen. It shows up only when screen is showing white and its like a light yellow (tobacco stain) colour. Gets better and worse regularly but is always there in some respect. This particualr problem I can live with as its only evident in pure white screen images which are rare. However, after having the TV about a week two spots appeared on the screen. One is a circular spot of sky blue at the bottom right of the screen up and in a few inches. The 2nd spot that appeared is in the very bottom left of the screen and again is a yellow discouration diagonal line. These are always there from the moment the TV is turned on and no amount of convergence tweaking in the Service Set-up will help. Other than these two minor annoyances, when the TV warms up after an hour or so, the picture is fantastic and I'm very pleased. Any ideas on how to clear these problems (although it sounds like its not gonna be possible) or why they are occurring? Many thanks for any assistance.
