Just purchased U-Verse 2 weeks ago, on my 3rd DVR unit. All 3 freeze when the tv and unit is powered off for more than 5 minutes. Once I power back on the screen is frozen. The oly option I have that works is to unplug unit and plug back in so it can reboot. The most recent service guy told me that he thinks it's the HDMI cable and my Sony TV. He recommended I try component cables. I did and still have the same issue, frozen screen. No one has an answer, any insight is greatly appreciated.

I have been with ATT Uverse for a couple of years.

I am currently waiting for the service person to come by again; DVR locking up again.

This starts with the screen going blank, then a message comes up saying searching for service, then a small gear comes up followed by the small gear being joined by a larger gear. This is usually a 15 minuet cycle. Last night it happened twice within an hour.  We has a repairman out last Saturday and now I am waiting for another.

If I did not like Uverse programming, we would switch cable providers; although we are about to the point where we have had enough.

Does anybody have any ideas why the DVR locks up? If ATT knows they are not saying.

I have notice recent problems w/the dvr's.  The issues are recordings being lost or a red X and I think it might have something to do w/an update.  Don't think your tv is rear projection, but we have also notice pix freezing when too close to a rear projection tv.  If you did just replace tv make sure all fitttings are tight.  A loose F-connector on the wall or back of the box can definately cause freezing.
