OK...been awhile since I've been here. I have three HR23-700s and working great forever.....connected to Whole-Home. Today I cam home and one of the three appeared dead.....no lights, no nothing. I unplugged and left for 10+ minutes and plugged back in....nothing. I tried pushing/holding power button on front....nothing. Any ideas ?.......and HARD reset secret key combo to try ? I do have the monthly maintenance (DIRECTV Protection Plan Monthly) so I guess next steps is to call DirectTV and have them replace the box ? Any guidance I'd appreciate. Also, what box will I get ?
