    On crt based rptv. I've seen this on several models over the last year or
    so. Picture can go quite yellow as set appears to hunt for best color after
    scene changes. I've had a hard time replicating it in the shop. Tweeking the
    G2 values can make it better or worse. I starting to wonder if it is a
    symptom the XDS buffer overrun problem. I now have a set that only does it
    on 1080i. I've found a few posts to other forums but no firm info.
    Anyone care to comment?

    Sorry. Currently its on a HCP4741W where the problem seems to be worse on
    1080i.

    Thanks Jeff:

    As a Samsung ASC, I have access to this information too. I find it really
    frustating that manufacurers will stonewall their servicers when there is a
    known problem for which they don't want to be held accountable for. Or,
    worse yet, they let us do the engineering and feed the solutions back to
    them.
     
  6. I wonder if this is similar to the problem in the Sonys that they extended
    the warranty on to four years. The fix is the CRTs.
