Sorry but are you saying that the blink issue was present pre-C series?
Not really sure what you mean AlbaJoe, but...
The C755 European, Nordic model of the TV was in the stores august 2010 here in Denmark. I bought my TV the 2nd of aug. 2010. It wasn't a pre-C series release. But if I'm right, the TV probably did hit the streets in other countries way before that time, as we here in Denmark (in many cases) isn't the first in line to get new models, hardware or anything that has with electronics to do.
But I had my blinking problems the minute I got the TV, and it was very bad with 1-10 blinks a day. So bad, that I contacted Samsung premium support for a repair guy to come out at fix it. The gut came, and swapped the mainboard, nothing else. Of cause as we know know, it doesn't help anything. Also new HDMI cables or different HDMI devices (I tried 4 different HDMI devices), will put an end to the blink problem.
Samsung has been doing something to the problem in a positive direction, with firmware updates. But I'm still not convinced, that they've solved it completely. But since the latest 3011 firmware, I still haven't seen any blinks. And I've watched a lot of TV from Christmas till now I'm still hoping for the best, crossing my fingers.
@e3henri, thanks for remote info...
About the remote, I've always thought it felt quite good & solid in build quality. So I didn't expect the buttons to stop working after a year. And I've really been careful, not pressing hard down on them. I also bought a C755 TV for my father in 2010, and he hasn't had any problems with the remote. So I guess I've just been out of luck with it.
I've not been able to reach Samsung yet by phone, but will ask about a remote replacement. Do any of you know what Samsung does, if you have a faulty remote (still premium warranty on the TV). Do they send a new remote to me, want to repair it or do I have to buy a new one? Then I might look out for third part another brand, maybe a Harmony or anything Logitech remote
