I have a RCA DVR40 with a 160 gb hard drive upgrade installed 12/06. This week, I noticed a loss of video output (blue screen of death) which would last anywhere from a few seconds to several minutes. Today when I turned on the tv, had a blue screen for several minutes before video came back on. It will often work perfectly for fairly long periods of time. On several occasions I have unplugged tivo and powered back up, which has also restored the video. I have lights on the front panel which do flash in response to the remote buttons being hit. No issues with pixalation which I experienced when the hard drive was dying.

From looking at a number of the other posts, I am guessing that the power supply may be failing, but wanted to make sure that is a correct guess before I go further. Thanks
