I just got a replacement unit for one that I had for about 10 months, and it was an older model with the light sensor in it. The remote works fine, but it has a dark spot about the size of this (O) on the screen. It is always there, even when you turn the contrast to where the rest of the screen is blank. Also, the display is not as sharp as my old (newer) one. I had to wait for about 10 or 12 days for this one and thought I would go crazy using 5 or 6 remotes. Oh well...
