[HN7000S] Sat-Out Shorting modem out

Last week my HN7000s modem went completely dark on me, (no lights) I fiddled around plugging and unplugging things in and out finally leaving it alone and just using my cellular air card for awhile. I looked over and noticed the HN7000s was back on after half a day of being off. Hooked back in and all was fine for ~5 days.

Modem again went all dark, after doing some googling I saw articles mentioning sat out being shorted out by cabling issues etc and sure enough, when I unplug the SAT OUT cable, the modem lights back up like Christmas, as soon as I plug SAT OUT back in it all goes dark.

I spent most of this morning swapping out my cabling to see if there was something shorting out the cabling underground. But finally went all the way to where the cable plugs into the radio and have isolated my issue to the radio and not any of my cabling.

My real problem is this hughesnet system was inherited from the previous owner, I'm very aware that I am no longer under any contract. I know at one time HN wanted to charge me $100+ just to send a service tech out for an old issue I fixed myself. I wouldn't think to much about upgrading etc, except my business should be getting its T1 installed in the next 2-3 months. Any suggestions would be appreciated.

Depending upon which generation of equipment you have, I may have a spare transmitter. Can you show us a photo?

Its the power supply, had same problem 2x in the last 3 years,
did all the same things you did with the same result BUT then I changed the power supply and that fixed the problem. It seems that
the power supply went bad, probably in a storm, by disc the Tx
it removes the load and the Modem then comes back to life.
I now keep a spare in stock.

BTW my system is also a HN7000S
Hope this helps and Good Luck Jim

Assuming you mean power adapter rather than power supply, I'm going to speculate that your issue may have either been coincidental. The job of the power adapter is to take AC/voltage from the wall socket and convert it to the DC/voltages needed by the modem. Protection from that side should be provided via a UPS device.

Protection on the cable side of the modem however, is internal. There are built-in circuit breakers that automatically shut down the modem when a cable short condition is detected. Most often this occurs as a result of a poor connector installation somewhere in the path. Even one strand of shielding coming into contact with the center conductor is enough to shut down the modem. And this feature applies to the SAT IN port as well as the SAT OUT port. That said, an internal short in either the transmitter or the LNB will also appear to the modem as a cable short.

So given that the power adapter is on the AC side of them modem, I am struggling to imagine how it's responsible for these symptoms

Are you for real, power adapter is just another term for a power supply, the more common term used in the industry?
“ A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (mechanical, chemical, solar) to electrical energy. Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from:
Electrical energy transmission systems or power lines. Common examples of this include power supplies that convert AC line voltage to DC voltage.”
You can struggle all you like, the fact is that in my case the power supply WAS bad and it DID cause the problems the OP stated. It is also a fact that replacing the power supply fixed the problem.
Now I was just suggesting a possible solution to help someone out, you on the other hand seem more interested in showing everyone how smart you are.
Good luck with that……… Jim

Search engine definitions don't impress me nearly as much as does an open mind Jim. I haven't posted here this long without having some idea of how this stuff works. But I'm guessing you're not "in the industry". Because you apparently don't realize that the Hughes (external) power adapter converts AC to DC, which in turn feeds the basic 6.5v and 19.5v inputs required by the HN7000S modem (internal) DC power supply, which in turn breaks them down to the various voltages and currents required by the modem board components, the LNB, and the transmitter. I just wanted to make sure which one you were talking about.

Stranger things have happened. But I've replaced several failed or failing Hughes power adapters over the last 12 years or so. Not one cable fault among them. And I've fixed even more cable faults, not one of them attributed to a bad power adapter. Given the info you provided, I'm still thinking coincidence.

P.S. If you still don't believe there's a power adapter in this equation, check your HN7000S owners manual.

I've swapped my input and output cables as well as replacing the first run (from the transmitter) with new cabling. So have eliminated any of the cabling. Despite what cable I have hooked in its always the TX radio one that is shorting.

I would try the power supply, just because its probably the least costly thing to attempt to fix looking now at where I can pick one up. I will try to slip out and get some pictures of the dish itself to provide more information on the equipment I have. TY for the suggestions and information so far.

Understand. Like I said, an internal short inside the transmitter can appear to the modem as a cable short. LNB too for that matter, except the issue would manifest itself on the Sat In port.

I was a telecommunications troubleshooter and satcom engineer in another life, which ingrained in me the need for redundancy. So if/when it comes to it, I've got a shelf full of spares for my own HughesNet system. They're easy to come by on eBay; »www.ebay.com/itm/USE-HughesNet-6···060b66f5

But I'd have to confirm which outdoor unit you have before I can point you toward the appropriate transmitter.

It is absolutely common for a bad transmitter to 'short out'
I have seen it many many times over the years

Between gregg and ebay you should be able to find another
Just need to make sure if the one you buy is still good, there are plenty of worn out or way past their prime ones out there - got to work that out with the sellers

I was able to get out and snap some pictures, if you need other shots let me know.

Also, the power supply on my HN7000s is a 45W, which seems harder to find at a good price.

Pretty sure that's the Anubis model of TRIA, and I have some transmitters to fit. But they're all 2 watts, which are more expensive than are the 1 watt versions. Also, your HN7000S must have been an upgrade. Because ordinarily it would have a 64w power adapter. If you do elect to replace it, don't waste time looking for a 45w, go for the more common (and more appropriate) 64w

I've been experiencing intermittent outages for the past two weeks. In some cases I can get back to work by rebooting the computer. In others only the Lan and Power lights appear on the modem & I can get started again by umplugging the modem.

The funny thing is for the past 5 days I've had the two light variety disconnect every afternoon. Sometimes it comes back by itself, other times it comes back while I'm talking to the tech.

Yesterday when my signal strength was 16 the tech said I needed to have the antenna repositioned. While I was talking to her it went back to 73.

Do modem issues appear intermittently? If so, can I just go on ebay and purchase a used 7000S modem?

Good idea to start your own topic on this issue, it's likely unrelated to the OP. Your type of outage is often seen during the height of the summer - is typical of older systems - and is very often caused by over-heating.

Next time it happens, take the garden hose and spray some water on the TRIA. If the issue goes away, it's overheating. To narrow it down, next time try to cool just the LNB. They usually go first. If that's not it, spray the transmitter. They overheat too, but the LNBs historically go first.

I am happy to report that the new 65w power supply arrived yesterday, plugged it in and everything lit up like Christmas. I have been connected without interruption since about noon yesterday and in fact my signal strength appears to be more solid than before. Thanks for your help guys, if this lasts the weekend we can officially mark this thing SOLVED.

//greg//

just a quick fyi- the 7000's were briefly shipped new in box for installs with a 45w power adapter, maybe for 6 months or so. techs in the field were complaining within weeks of their release, as we were noticing transmit issues. 64w power supply appeared to resolve the issue. thus hns started sending 64w power adapters with the radios, as the modems were apparently already boxed up and shipped out. anytime we saw 45w power adapters, we were to swap them out. it was obviously years ago, but i do recall when it happened.

You need to Mocap the outside cables. If they are not sealed you will find yourself looking at a new radio because they will allow water into the thing and burn it up.
