Call me mister unlucky, if you like, for having good hearing, but yes I did read the other LE37C650 reviews which mentioned "buzzing",but I still decided to go with it anyway. Big mistake, from the moment I switched it on, it was buzzing. I played around with the picture mode settings and the only setting I could use without it buzzing was dynamic, even then, if the picture was dark/black it buzzed. Also, if I reduced the backlight setting from 20 to 19, again it buzzed. At first, it was diagnosed as a faulty PSU, but alas, changing that made no difference. The next guess was a faulty panel(screen). At that point, I returned it. I have now got a Samsung LE40C650, having paid the difference for the larger model, and its perfect. I did'nt really want a 40 inch, 37 inch was plenty big enough, but at least it dosn't buzz, so its worth the extra. Have you noticed reviews of the LE40C650 do not mention buzzing at all. I think, Samsung should come clean and admit a problem with certain panel versions, fitted to the 37 inch model. Because, it was a month of hassle I could have well done without.
Don,t get me wrong, Samsung are great value tv's, I would'nt have got another otherwise, but I would give the LE37C650 a miss.Samsung LE37C650 37-inch Widescreen Full HD 1080p 100Hz Motion Plus Allshare Internet LCD TV with Freeview HD
