Looking for some advice regarding my R15-500. Haven't found anything that is similar to my situation. The following issue has occurred three times in the last month: I will be watching TV (live TV) and the picture will go Black, but the audio still plays. Pressing buttons on the remote causes the picture to go to static and no audio. The record light will come on. A red button reset will get me back to normal (after the reboot). No pattern so far. The first two times were within a couple of days, this last time it lasted a couple of weeks. Is my whole unit going dead or just the Hard Drive? I can possibly replace the Hard Drive if that's the problem, but don't really want to buy a new receiver now.
