I've had this unit for quite a while and it's been working fine until recently. It's started to freeze and I have to reset by unplugging. When it comes back on it has trouble acquiring information and gets stuck at 97%. It continues to try and gets stuck at 80%. It usually takes a few tries but eventually acquires the information. Today it's not working so hot. I can't get to live tv at all. Is it toast or are there some other resets or workarounds I could try?
