Jynxbox V3 lost satellite signal

[Canuckgold]

My Jynxbox V3 was working fine with the new TP updates until about a week ago when one morning I got No Signal on all transponders 110, 119 and 129. I have both an ATSC tuner and a JB200 tuner installed so I tried switching them around. The ATSC tuner works fine in either slot but the JB200 tuner gave no signal. I figured my JB200 tuner was kaput so I got a new one and installed it today. Well, I still have the same problem of No Signal through the JB200 tuner. I contacted the tuner supplier who said the new module was tested to be working before shipment. I have an Nfusion HD for testing and the signal comes in fine so the problem has to be with the Jynxbox receiver somewhere. Does anyone have any suggestions or is my receiver toast?

Personally I'd do a factory default and set everything up again. Something make have corrupted somewhere on you. You know it's not dish alignment, switch issue or line issue if your NFusion is seeing signal and as you say the tuner is new and tested. Let us know how that works for you.

Go into the receiver sat menu, look and see if the LNB power has been turned off, I don't know why but some times it will just turn off, if it's off just turn back it on.

what does it say when you hit Menu button then Tools then Sytem info..
Just Curios what it says for both RF/slots 1 and 2

[Canuckgold]

The receiver shows whatever tuner I have installed in which slot. I can switch the tuners around and the receiver sees them. The ATSC tuner works in either slot but neither the old nor the new JB200 tuner gets any signal on any transponders.

Make sure and module is fully seated as sometimes it appears to be but isn't then do as I suggested in post 2. You are installing the module with the box off I hope and the power cord unplugged as well as the lnb cable in disconnected. You can also factory default the box with the module out then turn off the box, install it and see if it recognises it.

I've followed all your suggestions but I think there may be an issue with another component in the receiver. I started again this morning after leaving the receiver off overnight. When I booted it up, I went to check the 129 transponders and found I had a signal. I scanned the sat and found a whole bunch of channels which worked. I then started to check the list of 110 transponders and found the first few were working but as I scrolled down the list, they stopped working. I went back to 129 and found they were not working either. I'm guessing some component is failing under load so I'm guessing I'm going to have to have my receiver repaired.

Get a quote first as a new box is probably going to cost about the same unless you know someone that repairs electronics.

What file are you using on the V3 receiver ? A friend told me that he is using V15 file and it is working fine on the original Jynxbox receiver.

[Canuckgold]

I've tried using both 239 and 243. I had 243 loaded and working for over a year before the failure. I'll give V15 a try tomorrow but I'm now convinced there is a component failure in the receiver.

these boxes have been overheating w/the turbo/8psk TPs .. try removing the cover &/or a laptop fan

[Canuckgold]

I got the tuner vendor to send a fully tested replacement. It arrived on Thursday and it's been working perfectly ever since. It's a shame I had so much grief with the first replacement because I thought maybe the receiver was at fault. I would insist on having replacement tuners extensively tested prior to shipment in future. The defect rate seems to be incredibly high.

You need a power inserter or an old DN receiver to power the LNBs & a fan, if not your new tuner will be dead soon.

[Canuckgold]

I'm using standard LNBs which don't draw as much power as other types. The new JB200 also has a much bigger heat sink than the original which lasted almost 3 years. I've taken the cover off the receiver for now so it will run cooler. I'm also trying to get some repair information as I understand these tuners can be fixed. I have a digital multimeter and moderate soldering skills so I'm looking for specific repair instructions if anyone has them available.

[Canuckgold]

I drilled a bunch of holes in the cover over the CPU and JB200 area and added a fan but the result was too much noise so I added the heat sink from my old JB200 to the new one and now its running cooler. The new JB200 has a heat sink about twice the size of the original so hopefully the combination will ensure longevity. I still have the cover off while I source a quieter fan or laptop cooler.

Check db level on the fan or laptop cooler before purchasing. It is usually marked on the fan itself. The lower the rating the better.

[Canuckgold]

I found a fairly quiet fan but my wife thinks it's still too noisy so I'm running it with the cover off. Interestingly, I found that the JB200 tuner board heats up to around 140 C when in use. If I switch to the ASTC board, the JB200 cools down to around 80 C. Is there a critical temperature limit to be avoided?

140 celcius?Is that what you typed???You must mean 140 farenheit.If that's the case,140 isn't too hot for a reasonably made component.
140 celcius the thing would be melting...or on fire.That's 284 farenheit

Not sure how your powering that fan but if it's a 12V try find a power supply for 6V. It will slow it down and run much quieter.
I actually have a 12V running on a Prosat with a 4V supply and you can't hear it at all and there is more than enough air flow.

When I put 12 volts to it, it sounds like a hover craft. LOL

I didn't know that.I got mine running on a 12 v power supply but noisy and not wife friendly.I will look into a lower power supply when I get a chance.

Strange issue with my V2. Do a factory reset and dish settings... Good signal ... But when I put off my receiver and later put it on , signal is lost....Any idea??...

[hutch]

Look Larry,,,If you indeed have reset the TPs...

try pulling the plug & letting it cool down,,, pull the cover off & w/luck the JB200 module will revive... if not replace it...

[Anubis]

I have seen the issue before and usually if you change the channel you are on to another and wait a few seconds the signal will usually kick in. Not exactly sure what the cause of this is but if that does not work simply hard boot the box. If you are turning off your box for say the evening I also recommend turning it off with the remote then turning the back switch off as well if the switch is easily accessible.

[larryg]

Thank's guys...Was indeed a JB200 module overheating issue ...Pull the cover off and put a fan and resolved the problem !!
