I see an FCC label on the DECA unit but not a UL or ETL label. Those are the labs that test things for safety. I don't even plug in a 5v or 12v wall transformer unless I see a UL or ETL mark on it.

These agencies test for things like this.

I thought about heat build up but the television stand where the dvr and dvd disc player are located is open in front and back so I would think there wouldn't be any heat build up. The more I look at the burnt ends the more I think there was some sort of short. What caused the short is a mystery because of the way it seemed to slowly deteriorate.

I keep looking at the photo.
I see the coax is what overheated and caught fire in the end.
The receiver can only output 13/18 volts and less than half an amp.

It's too late to know, "but" seems like the coax had a short, or stray strand of the shield that caused this.


Other reason could be if the shield wires didn't come in good contact with F-connector (?) at DECA box; that could create some resistance ( a few Ohm) so increased voltage's drop to that level and the shield connection become a heater.

I didn't realize that Directv contracted through GM for these :confused:

Update: I just got off the phone with Taven, great guy. He was actually appalled when he read the notes from last night and saw what little was being done because of the issue. So now two HR24s will be installed Monday, the installer is instructed to go over every connection from dish to boxes and look over the burnt deca. Also he added Showtime and Starz for 6 months. When I told Missy that there won't be any more external deca's in the house she was greatly relieved as she has a deathly fear of fire...fire where it shouldn't be. I'm relieved also.
Thanks to everyone who expressed concerned and relief that nothing really bad happened. I appreciate that.



since the hr24 has an integrated deca unit. doesnt it mean that the same hardware from the external unit be there or is the deca built into it in a different way?

Same or similar chips. The suspect here is the connector. I see shorts in the field daily, so this is very concerning if that is the true cause.

Thanks for the follow up. Kind of sucks that you had to call multiple times to get this fixed the right way.

BubblePuppy, you might want to log this problem at http://www.cpsc.gov/. Yes DIRECTV will be fixing your problem it might be worth for the Consumer Product Safety Commision to know about something that might have started a fire.

See post My Setup for configuration info.

If that broken end of the cable is permanently attached to the DECA box then DTV must recall all such DECA boxes before real tragedy will happen.
It it detachable short coax cable then quickly replace all of them.

It was the permanent "Sat Rcvr/ Power" end.

It's just a pigtail attached to a connector and then shrink tubing.

Is there F-type (threaded)connector inside under shrink tube ?

It looks like it, but I'm not cutting one up to find it.

That would bring DTV to expensive recall - all DECA of the batch must be recalled immediately !

It is just a normal connector inside it. Some of the new black ones come loose, so we have to tear off the shrink tube and tighten it up.

Just got the call from the installer...he is on his way with two HR24s. I can't be there but Missy knows what to do. Also the installer is not to take the burnt deca.

Wow, I just saw this thread. What a relief that you came home when you did. I'm glad the second person at DirecTV took appropriate action. Perhaps someone here at DBStalk with access to DirecTV can find out who to send the burned DECA to for analysis. Glad your family is OK.

The mods here certainly do have contacts, but if it takes that, then I'd think that's a failure. DirecTV should initiate getting it back to analyze.

I'm glad that I no longer need them.

I did get a call from Bruce from Directv. They are sending a team out to investigate this. This team may be flying from CA. I'm not sure. I'm keeping the HR20 and the deca for their investigation.
Here is what I don't get, I talked to 5 people between Friday night and Saturday morning, no one seemed to have a heightened concern about one of directv's supplied equipment catching fire. I would think one of the five would have contacted someone higher up.
Bruce said he found out about it by reading my post, perhaps someone here alerted him.
Anyway it has moved up the "fire" ladder, so to speak.

Addendum: I did get a pm requesting my contact info so I could be contacted directly, so there was some Dirctv/DBSTalk communication.
Thank you D.B. for that.

I can't imagine a front line CSR has anything in their script/training to deal/handle something like this.

I did talk to a supervisor on Friday night. But yea...there was a lot of stuttering going on and I'm sure a lot of page turning.
The tech I talked to Saturday was very knowledgeable and never once resorted to script talk. In fact had this happened even ten to 15 minutes earlier and we had been home he would have been the one I would have talked to, but he was leaving for lunch when I called.

It is quite encouraging to hear they are taking this all very seriously and going to that length to investigage the matter.

The final findings will be very interesting.
