Hi, what an absolute cracker. I'm still trying to find my way around all the settings and features but I'm so pleased with the quality of the TV and the picture. Mind you for a 55in I think the single centre stand is a little flimsy. However, I have a question and wondered if anyone can enlighten me. At the bottom right corner under the frame is a little attachment with what looks like a red LED showing. I can't find any info what this is. I'm assuming it's to do with the infra red remote control, possibly the receiver, but wondered if anyone could tell me fir definite.
