Samsung: wandering white balance

[Bob Loblaw]

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.

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.
