Is the flickering happening on all inputs, or just the cable box (or coax in the wall)?
Does it do the same thing if you use a DVD player or other device?
just brought home brand new LN46A650. To my dismay however I noticed
on the 2nd day that there was flickering on the screen (with some noise coming from the speakers) the first time I switched my LCD set on in the morning. The problem went away after I turned the power off for few seconds. I'm using HDMI cable to connect to my comcast box.
To test this further I turned the TV set on and off couple times and the problem reapppeared on the 4th or 5th try.
I also noticed once that the flickering (with slight popping noise) would appear sometimes when I was switching between the channels (this happened only once)
NOTE: the flickering/noise would go away after I turned off the TV.
I thought I've done my research and chose SAMSUNG brand wisely but I'm having second thoughts...????
I'm using MONSTER power surge protector so I'm thinking this is not electrical issue.
I appreciate quick response to this matter - I have only few days to return this LCD to the store.
