I have a 2500 that displays channels fine. But won't download/update the guide (all show as 'to be announced').Also the time on the front if it just display's 12:00 and never updates to the proper time. I have unplugged for several minutes and restart with no luck. It has worked for a VERY long time without fail. What are my options to get this replaced/repaired with something that still has an older s-video or composite output on it? I have this connected to an older TV that does't have HDMI.
