I have noticed muted color in the two grey bar areas of my 50HX81 Toshiba while watching in 16:9 format. The set is only 10 months old and was calibrated by an ISF certified technician 6 months ago. I admit to watching 60%-70% in 4:3 mode for standard broadcast stuff but I thought Toshiba put the grey bars in to avoid uneven degrading of the phosphors? I do have a factory authorized serviceman scheduled to look at the problem and it's still under warranty but I was wondering if this is normally a problem in such a short period of time? I have taken to watching standard broadcasts in streatch mode but I don't really concider this an acceptable "fix" for future problems after my set is serviced.
