Hi,
I feel like I'm in an episode of 'The Twilight Zone'!! Since I got it, perhaps once a month at most, my PS50C7000 would very occasionally 'blink'. However, that was until the last few weeks, when it has started getting progressively worse and now is often doing it 3 or 4 times in an evening (it's got so noticeable that even my kids have started seeing it). I have a V+ box, so it rules out any sky connection. Then even more strangely, on Monday night whilst I was watching it, it just switched itself into standby and back on again, something it has never ever done before - it may well have been trying to do a software update as I know it does automatically check with Samsung's servers (we have a wireless dongle) , but it has never ever switched itself off and on again autonomously.
I did have a look on the internet and found a very long and interesting discussion on the 'AV******' site - (* being the places where the romans used to meet to debate), and this is apparently a known fault - even now a year since the TVs release there is no actual fix for the fault. My 7000 was a direct replacement from Samsung for a B850 with a 50hz motion edge tracking problem, and I have to say Samsung's customer service was exceptionally good indeed. However, as my 7000 is already an exchange for a previous model and is now over 12 months old, I probably won't get any further with mine, and I'm not sure I really want the expense of replacing 4 sets of infra red 3D glasses with their newer bluetooth ones if they did offer to exchange the set for a PS51D8000 which they seem to be doing for other owners of the C7000 with the blinking fault.
However, I'd be very interested to hear what Samsung have to say to you about this fault and what they offer you as a solution.
Regards
Rob
