Need help with 921, screen goes black except for a very thin line at the top and you have to hold down power button for ten sec. to re start every morning when I turn on the TV. Seems to be locking up more often too. Is this thing on its last leg? I am still having a hard time giving it back...

Can I now get the HD PK's on Dish while still using my 921? Do I have to invest again?

Just got 921 and can't get caller id to come up. Talked to Dish tech no help. Any ideas on what to do.
