After hearing all the good things about the le26r51b, I went out and bought one. And for the most part, I couldn't be happier about this tv. GREAT image and no fan noise to speak off. However, it DOES have a very VERY annoying sound coming from the lower-right and lower-left corners of the speakers. It sounds a bit like "BEEP, BEEP, BEEP, BEEP, BEEP, BEEP, BEEP..." and it doesn't stop. It doesn't matter if the tv's on "mute", if I adjust the picture settings or anything... it just keeps going. And when I turn on PiP, it goes crazy. It sounds a bit like a squeaky fan or something, but there aren't any fans in the speaker-area, is there? To be honset, the noise is not as bad as that in a CRT-tv, and if the noise was constant ("BEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEP"), I wouldn't mind too much. But a sound that just keeps going on and off, is VERY annoying. My question is: Has annyone else had this kind of problem with the LEXXR51-series? Is it something that's normal for a Samsung-tv? Is there anything I can do to make it stop? PLEASE HELP!!!
