I have an Anthem AVM50 that I have had for several years. Approximately three weeks ago, it started coming on by itself. It will quickly cycle through the inputs and usually stop on DVD. If it is left on, it will repeat this process approximately every five minutes. If I then turn it off manually, it will also usually come back on and within a few minutes. When I remove power, wait for a few minutes, and then restore power, it may repeat the problem almost immediately or wait for two or three days. I have placed all my remote controls in a drawer to make sure they were not randomly causing a problem. I even taped over the remote sensor. I checked to make sure all cables were connected properly.
Anthem technical support had no suggestions other than to send in for repair. I thought I would ask this forum if anyone had experienced a similar problem.
