I have a Sony XBR 36" HDTV that intermittently has a very yellow cast to the screen image. There is no consistency as to when the yellowish cast appears. The TV might have been on for an hour or more or within a few minutes of starting. Normal color can and does reappear without turning the set off. Recorded shows on the digital cable set that were normal when initially recorded have the yellow cast so I am comfortable it is not the cable box have problems.
Any thoughts....
