My LG 37LC2D stopped responding to my remote control over the weekend. At first I thought it was my remote (Harmony 550), but no. I tried the supplied LG handest and still nothing. No control whatsoever. After skimming through a few websites, I found a report of someone experiencing a similar problem after switching from VGA to TV mode with their 32LC2D. That reminded me that the last thing I did to the TV the day before (when I last used it) was to switch my upscaling DVD player into "auto" mode for detecting what output to send the TV through the HDMI cable. The TV is responding to my remote again, but only after changing the DVD player output through the HDMI cable to 720p, rather than leaving it to decide itself. Anyone else seen this? Is it a common problem?
