Has anyone else had this problem? My unit has been working fine until the last three weeks. i've noticed that when i power the unit to stand by mode i can't get it to come out of stand by. no blue lights anywhere. I've tried hitting the power on the remote and manually pushing the power button, but nothing ever happens. it just stays in stand by. The only way to fix it is to unplug it. the RBR doesn't work when this happens. I stopped putting it in stanby mode for the last couple weeks and it's been fine until this happened the other day: i've notice that sometimes the channel doesn't change when i type in a number (it is a channel i receive). I'll punch in say 298 enter and I can see the numbers come up, but it just stays on the same channel. Just curious if anyone else has seen this.
