My current setup is an HR21 with AM21(OTA). I started getting this message yesterday on one of my OTA channels. Today ALL my OTA channels display this message. I checked my connections...they're fine. I even did a reset...still nothing. Normally when I press the on button on my remote, the TV, HR21 and AM21 start up. Likewise when I press the off button everything shuts off. But since I've been getting this meassage, the AM21 light stays on when I shut everything off. Anyone else experiencing this?
