In hindsight (of course) there were a couple of warning signs that something was going on.
First, when I would turn on the living room tv there would be a notice that there wasn't a connection to the satellite, but that would go away within a few seconds. I never put the HR20-700 in standby. I thought that was a little weird.
The second warning started Thursday night. we were in the living room watching a movie that was recorded on the bedroom HR23-700. The movie disappeared and a notice popped up indicating that the home network connection was lost. I had to run the network setup on both dvrs to get it back. This happened several more times that evening. It continued Friday morning. I was thinking that since I have the protection plan I would call Directv and schedule a service call. We went to work, came back after, watched a bit of tv and then went out to dinner. It was just ten minutes after we got home and turned on the tv when Missy was walking by the tv when she said she smelled something burning. The rest is explained in the first post.
Now I don't know if the deca would have caught fire without the tv being on or not. But caught fire it did.
A new deca is being sent (the black one), I took the white one from the bedroom dvr and connected to the living room unit. So far no more fires. ;-)
As for as my avatar, that is a picture of my constant companion and canine soul-mate of 15 years Smoke (Cossack's Smoke-In-The-Aire). It was taken when we were moving to Florida, crossing the Georgia/Florida state lines. Sadly two years ago he crossed over the Rainbow Bridge. I still miss him very much.
"I'm sorry we nearly burned your house down, I can offer you $10 off for the next 6 months,....." Hmmm....not sure if that is a joke or not but it is better than the response from the first csr I talked to, which was...."What do you want me to do about it?". I won't repeat my response.
I'm thinking about calling Directv and seeing (under the protection plan) if they will replace the two dvrs with the HR24 with the built in deca. I don't have a lot of trust in those external ones anymore.
