Have you ever heard of this before? I have a Sony KDS-A2000 SXRD projection tv. We've had it about 5 months. We were watching it last night and everything was fine. This morning I turned the TV on using the remote. It began changing channels by itself and it won't stop! I can't even access the menu or anything because it keeps clicking away. It isn't the remote - we took the batteries out. The button on the TV isn't mashed in - I checked it. It must be something internal. We tried resetting the TV, but that had no effect. I'm going to call Sony once I get home from work, but I was wondering if anyone had ever heard of anything like this before? Any insight? Is it going to cost a lot to fix? Thanks!
