This was scary tonight. All of a sudden this evening we had noxious fumes fill the house. We got the kids to one area of the house and I started running around to figure out where they were coming from. I determined it was from one of my receivers --- an HR23-700. That unit had stopped working a couple of days ago, I had spoken to DIRECTV yesterday, and they were in process of shipping me a new one. (Unfortunately they say another HR23.) I had not unplugged the one that stopped working. Little did I know what would happen this evening. I could not help but open the box after this occurred this evening. One of the components/resistors is totally fried as well as the surrounding board. Has anyone heard of this happening? The funny thing is that this is the only receiver I have that is not in an AV cabinet. i.e., it had totally unrestricted airflow around the whole unit. I called retention saying that I had no confidence in getting another HR23 after this situation. It could have been MUCH worse had we not been home and immediately unplugged the unit. They said they could have someone come out and look at the installation after the new unit arrived. I don't know what good that will be as this was internal to the unit with nothing around it. Alternatively they said a could upgrade to a different model, they would pick up the cost, but that would require a new 24 month agreement. That does not seem right as well. Thoughts? Recommendations of how to proceed? Thanks.
