A Melting DirecTV Tuner?

Posted by on Sep 16, 2009 | 12 Comments

Today I discovered a friend of mine had a squirrel chew through the neutral line on the power pole outside their house. The end result was nearly every appliance in their home being fried with raw current — apparently the breaker box only tripped one of the breakers.

Where things get really weird is that during the cleanup from the event, they discovered that their DirecTV box was leaking a significant quantity of a water like liquid. The consistency was definitely water-like, not like melted glue or paste of some sort. And even stranger was the quantity.

What in the heck could create this quantity of mysterious liquid from inside a DirecTV tuner box? They are certainly not water cooled. And had something have melted, surely the consistency would have been less like yellow water and more like a sticky paste?

It is at this point that I must ask for your thoughts on the matter. The only thing I have ever heard of along this line is water coming in via the coax cabling — and even this is very rare. If you have any ideas, please hit the comments to share your ideas as to what might create this kind of liquid from someplace that there should not be any.

    Not knowing the insides of a DirecTV box and only going off of your description, my guess would be the liquid from a liquid filled Capacitor from the power supply. It shouldn’t be a lot of liquid though. These would be rarely used in any other part of that type of device.

    Sounds like capacitors to me

    Matt, I’m thinking that the squirrel somehow got to that tuner and took a big whiz. That’s one pissed-off squirrel! Mystery solved!

    there isn’t any liquid in the box
    you’re crazy

    Just a hunch, but I suspect that the liquid leaking was from the power supply electrolytic capacitors. Many of the larger can type electrolytic caps used in power supply applications have a liquid in them. If a large surge came in it’s possible that it blew the cap apart and that’s what you’re seeing. Shouldn’t be much…maybe a few teaspoons at most is all I’d expect to see even from the largest ones.

    The liquid you are referring to is probably coming from one or more electrolytic capacitors on the pc board of the DirectTV.

    Matt,
    I f it really is water, I would check for leaks where the cable enters the house. Sometimes water will travel along the cable, especially, if the cable enters at a highs point than the tuner.

    I think you’ve got one hell of a conspiracy-theory story on your hands.

    LOL, I totally had the pee jokes coming. Set myself up there…heh.

    And thanks all on the capacitors, this makes a lot of sense. Passed this on.
