Hi everyone, i'm new to this forum and i would like to know if anybody has the similar problem. The problem is that sometimes when i turn on the tv, it flickers for a bit, i mean the image goes darker then lighter, if that makes sense.Now i understand this is normal when you turn the device on, my problem is that sometimes it makes this effect during movies (very rare, 2 times only) and when playing xbox the other day it started to produce this effect all over the picture, then it went dark and there was only sound (this only happened once. Does this have to do with the audo diming issue (i've read some threads about it) or do you think it might be faulty? I bought this tv last October and i never noticed this until a couple months ago, but since it doesn't happen that often i thought it should be normal.I just don't want to go to the retailer and when asked to show what's going on, nothing happens, because like i said it happens sometimes but not on regular basis. If anyone had a similar issue of someone could give some tips on how to know if it a faulty set, i would appreciate. Thanks in advance and sorry for the wall of text.
