I had DISH installed in Jan. '09 & had no problems at all until early July 2009, when my original 722 started acting up - restarting repeatedly, hard drive running at all different times of day or night, and could not watch either TV1 or TV2 until the rcvr finished resetting.
I have had the same problems as “richjh213” since August. Sometimes I also get a blank TV screen but the guide will display then I can go to “My Recordings” and play a recorded show but again just a blank screen then fast forward then back to “Live TV” and the TV programming will return to normal. I am on my 6th VIP 722 since 5/08.
The 722 replacement unit #2 replaced in 8/09 also had a DVR hard drive that was locking up so after reading some of the threads on this site I think the #1 & #2 722 replacements may have been caused by high DVR hard drive temps >142 deg (menu 63 counters). By placing the 722 on its side and elevating it so that fan air moves through the unit I have gotten my Avg. Temp down to 107 deg.
722 Replacement units #3-#6 DVR hard drive functions seem to be working fine but again like “richjh213” these units keep locking up. I just double checked the house electrical and no open grounds or REV polarity. Over the past few months these 722’s have been plugged into the wall or a “APC” surge protector. I am going to try a different wall plug though.
Also not sure if dish antenna grounding has any impact on this issue….but I found some loose Sat cable connections and some of the Sat cable grounds are rusted up and some of the copper grounds on the house where the Sat cable enters the house were a bit loose. I tightened everything down.
The video feed is also via HDMI on a Harman Kardon AV receiver and optical audio.
During the last 2 Dish Tech calls the tech said they were receiving info from the 722 over the network that my 722’s were bad…..one tech referenced the screen (613 details (Value:7: -2)) indicated that the hard drive was bad. The last three 722’s have had this value.
If I don’t get this fixed fast I think I am going back to Comcast…..I can’t believe I am saying this but I would save a lot of money….of course cheaper programming but at least it works most of the time.
