My DECA is screaming

    The power inserter/DECA unit on my HR34 started shrieking tonight. No idea about the cause. It was a moderately loud, continuous whistle.

    It finally went away after I unplugged it from the power source. After I plugged it back in, the shrieking went away and everything works fine, as far as I can tell.

    I'm wondering if it was a leaking capacitor. Will D* replace this unit at no charge, or should I just buy a replacement on ebay or something?

    Need more clarification....

    DECA is an internal component within the HR34.

    So is the HR34 making the sound, the power supply, external CCK unit, or something else?

    Portland,...
    Sounds like a power supply going bad. I had a power brick sound like that once before it died.

    I wonder if this is a SWiM power inserter you're trying to describe.

    Yeah...I was thinking that too...and trying to narrow things down to just what was being described.

    Well there was a DECA reported in this forum that went on fire.

    We don't know if it's even the DECA itself at this point...the OP hasn't added the necessary information to diagnose.

    OP here.

    It was definitely the DECA. I believe it is used specifically to bridge my wired ethernet to the DECA cloud. I understand that the HR34 does not have a need for a DECA under normal circumstances. There is a power adapter hooked up to it, but I don't recall if it was the SWiM Power Inserter or not.

    Anyway, everything is working fine now. I wonder if I should just go ahead and replace it just in case.

    So it was the device that has the Ethernet cable from your router that was making the noise? That would be the Cinema Connection Kit. It would have needed a PI (power adapter). If you do have a HR34 and it is near where the CCK is located, just completely disconnect it and plug the Ethernet cable into the HR34.

    I'll give this a try. I seem to recall that plugging the ethernet cable directly into the box would disable the internal DECA. Perhaps that was the case with the HR24. I just got the HR34 about 2-3 months ago.

    BTW, I do not have a CCK, which if I recall is basically a wireless ethernet adapter. I have a CAT6 cable that I ran from my home router to the TV location. The box in question was definitely a DECA which may have been used as a CCK.

    I'll have to look up some of the wiring/topology diagrams from a couple years ago to remember exactly what it was called.

    I had that DECA set up for the internet connection. It was left over from a previous dvr, just get rid of it if the 34 is close enough to your router or can be connected to it by an ethernet cable. Everything works just fine without that set up.

    being this is the location of the previous hddvr as stated, it is true that with previous model of receivers (the hr24 for example ) having the ethernet plugged directly into the receiver it would disable whole home. Now being you have the hr34 in the place were the older one was you can remove the deca and plug it directly into the receiver as it has a built in cck and it will not interfere with whole home as previous one did.

    Now saying that you can also probably clean up your wires a little, Not knowing how everything is set up and what you have I am going to be doing some guessing here. I am going to assume this is were your power inserter is also so you probably have the cable coming in and going to your power inserter going to power to swm port, on the power inserter "to receiver" i is probably going to a 2 way splitter, from the 2 way splitter to the receiver and the other to the deca ( cck ). If you do away with the cck you can also do away with the 2way splitter. so now you can just have the cable going into the power inserter from outside and one cable from the power inserter to receiver.
