I have the 3805 for about a week and am having problem with the remote. Within the first day, the back lit lights for the "source" inputs selection (DVD,CD,VCR1.....etc.) suddenly turned off. I could still select the sources by pushing the buttons blindly but I could not get the back lit on. A day later, I picked up the remote and the back lit lights came back on. This lasted for about about 5 days, then it happened again yesterday. I may find it working again when I get home after work tonight. Has anyone else experienced this? Any helps will be much appreciated. When the back lit lights (again, only the source inputs selection ones) are gone, the "source" button shows a single arrow and instead a double arrow when it is working. Thank you in advance.
