Call Samsung Customer Care or your Local Samsung Authorized Dealer. Your set
being under warranty should be a service related issue. Why some of the post
refer to you not wanting to do this yourself is the fact if you FUBAR it
then it is time/material cost to you since you voided the warranty. There
are way too many vairables in the service menues of these sets, incorrectly
adjusting some of them may produce very undesirable effects, both to your
set and your wallet. Yes, it is an economic issue on the part of service,
and the customer. Same idea as buying that brand new Chev Corvette and then
changing the eprom to a high preformance item. Agreed, a lot of fun finding
out just what it will do without reigns, however, you just produced a
$45000+ libality because no more GM warranty at all.
If you are real careful (take note of the original values. try small changes),
there is little danger of damaging your devices by "hacking" the service menus.
IMHO it's almost the same as "tweaking" your Windows' registry or your BIOS
settings to get more speed. If you change the Windows registry in the wrong way
you may trash settings (requiring system restore/reinstall), and in a PC BIOS it
may not boot anymore unless you reset everything.
