Well, the TV self healed. Samsung were able to set me up with their servicing team. Those guys called me and when I spoke to them, they said they got the details from Samsung and they would come and replace the screen. I was taken aback, because 'what has the screen got to do with the remote sensor acting up'. I didn't want them to change the screen as I was concerned it might crop up some other issues.
So I told them to give me a day or two to decide. In the meanwhile, I search the net and obviously couldn't find anything.
This is what I did:
1. I removed batteries to all remotes (cause I thought the remove was jammed and was continuously sending signal to the tv)
2. I shut down the TV and removed the plug
3. I disconnected all cables, other than power.
Kept it like this for a day.
Next morning, I went and switched it on, and voila, the led stopped flickering. I kept the tv on for a couple of hours, without touching anything, and then gradually put in one cable at a time. Started with aerial and tv remote. then lan. then optical.
and the issue has so far not come back.
I read somewhere that it might be the optical cable which might have caused the issue, but i don't know if you have an optical connected.
so in brief, just unplug everything and keep it disconnected for 24 hours.
Let me know if this works.
All the best. I know how stressful this can be.
