Samsung HLP4663W 46-Inch Widescreen DLP HD-Ready TV Monitor
Samsung 46" DLP HL-P4663W
I wanted to add to the above review.  I just purchased this tv and have 3 other friends with either this one or the 50\\".  All have had this problem of the TV cycling on/off.  The problem turned out to be power filtering.  Make sure you use a power strip with power filtering.  The $80 Monster Cable strip has a filter on it.  There are cheaper ones.  This has cured the problem for all three of my buddies.    So far I am very happy with the TV.  Excellent brightness and very true color.  I have noticed an occasional mismatch of the sound to the picture.  The mouth keeps moving after the words have been said.  I turned off the DNR and DNLe but made no difference then I turned off LNA (Low Noise Amplifier) and havent noticed it since.  Anyone seen this?  --------------------  2 Weeks after purchase    Well my TV did the on/off cycle thing once so far.  Note that I am not using the $80 power strip but the $30 strip.  So I would suggest adding $80 to the price and get the power filter for sure.  I am getting buged by the auido/picture sync.  I am finding a couple of other's seeing the same problem.  It comes and goes and is normally associated with a \\"live\\" broadcast.  For example in the bid debate tonight it was very evident on all broadcasts in HD or not.  It does not matter what combo of settings you try or if you use an analog or digital cable.
