is my lnb on some kind of timer?

ActingDanClark

Had set up a humax foxsat for the folks, dual input from a quad lnb. Bought them a walker dual input (saorview and freesat) tv Saturday. Used one of the cables from the humax to set up and all was good. Last night though both tv and humax indicated "no signal", so no freesat programs. This morning all the channels were fine, then later gone again, both on the tv and the humax. Has the old man somehow switched off the lnb, and if so how do I rectify?thanks In advance!

Liameter-thanks. Thing is, service was perfect til New tv, and now theres no permanent signal to either the tv or the box. Dish is well mounted and not exposed. There's no obstruction eg large tree.

damian say how you have connected sat cables, why use one of the cables from the humax?

ActingDanClark

With the humax,to enable viewing while recording two cables from the lnb are necessary. I used one of these direct into tge tv as it has an inbuilt freesat tuner. All was fine initially, but satellite channels vanished, then reappeared, and are now absent again

swoofer

when you set up the humax if i remember correctly it ask if you have a dual feed or a single feed, and then checks automatically, you cant then disconnect one cable, to illustrate, take out second lead from humax and tv should work. its too late for me to look at my humax

How would the tv know, or why would it care, what is connected to the other lnb outputs?

swoofer

oh go to bed you

oops

ActingDanClark

Thanks all, ill try that with the humax, might try loop from lnb out. As was asked though, why would any incorrect set up of the humax influence service to the tv freesat tuner?

swoofer

dont, just unplug sat cable from humax first, then if you have tv already connceted by sat cable disconnect it, check f connector is made up properly and re- connect. this may not work but it can help. then if tv sat works you could start on humax ie do a re-install and set it up for one feed.

i am just up! waiting for post so be quick and report back.

NB always have boxes switched off when taking off leads.

get the lnb working first and then we can tell you why it got knocked out

Don't do that. If you need 3 feeds from the dish then use 3 feeds. LNB out is not for a third feed.

'Loop out' on the Humax is primarily for feeding its own 2nd tuner in single cable mode (where you don't have a 2nd feed from the lnb available): this is a setup option & lessens the confusion caused by not having all channels available for watch/record by greying them out in the menus.

ActingDanClark

That was my thinking in looping from lnb out to lnb 2. Update- disconnected all 4 connectors from lnb and left it overnight(this wasn't based on any tech info) reconnected all this morning having unplugged power and f connecter from humax. All sat channels working on tv currently, gonna reconnect humax tomorrow morning with remaining feed to lnb1 and a bought cable from lnb out to lnb 2 in. Not in a position to report current status as its in the folks house 10 miles away!
All your input is greatly appreciated- connects are all good !

Peter Rhea

There's nothing in an lnb that can be 'reset' by power-cycling.

ActingDanClark

My suspicion was that some setting between the lnb/pvr had been altered via the hymax remote. I couldn't understand why the channels would dissapear from the tv, even if something had blown in the pvr

swoofer

well all I can say is that my suggestion worked and that is good news because otherwise if it did not it was a blown lnb or... the dish moved. When you set up the humax you are going to be in a right pickle if it happens again.

ActingDanClark

That's the fear

swoofer

but if you listen to me you wil be fine, will you yourself be accessing the humax.

ActingDanClark

Yeah, but I've 2 at home, never a problem, which is why I bought one for the folks,I'm kinda tied to one lnb feed in tho!

swoofer

why have you one lnb in, you can do a loop out trick, thats what the loop out is for ie people with one feed. have you a quad lnb at home?

steveon

you have to do the loop out from the back of the humax and u need to set it up in the menu to tell the box u are using only one cable, otherwise you will have exactly the problems you have been experiencing.

Can you not leave the 2 cables in the humax and have a new cable ran for the tv combo?

ActingDanClark

the other 2 cables are spoken for and its a difficult run if i was to replace the quad with an octo( as in the 4 cables are in a conduit under a lawn, sealed at both ends with silicone, before anyone asks)

Peter Rhea

A multiswitch would probably be the best way to get more receiver feeds, then. I presume the satellite tuner in the tv is for your folks' convenience?

Did anyone ask yet which cable you originally disconnected from the Humax?

The problem with the tv's satellite reception is/was more than likely a loose connector or short. I don't know why anyone would want to cause confusion by suggesting it's some way connected with the setup of the Humax.

swoofer

got it in one, we dont actually know how the cables are connected. even now 2 cables are accounted for but where do they go to? I think its a quad with 2 to sky, and 2 did go to humax, then op used the loop out of the humax to the sat connector on the tv. I never used the loop out on a humax to another sat and never had a need to. I do know it was to be used if you only had one feed, saves money. All I can say is that when you set up the humax it does ask if 2 or one connection.

his best bet is the loop out trick.

Peter Rhea

He didn't use LNB1-out to connect the tv. Maybe he removed the feed from LNB1-in & this caused the problem with the Humax. I don't know how exactly it utilises each tuner, or how it would react with only tuner 2 connected to the dish.

swoofer

what did he use?

Peter Rhea

Are you just taking the piss now? One of the LNB feeds to the Humax. He didn't say which one, afaics.

ActingDanClark

I disconnected lnb 2 from the humax and used that to set up the tv, and yes, that's to minimize number of remotes. That done, to restore functionality to the humax I attempted to provide service to the tv tuner via the lnb out from the humax, and lost everything. Then removed lnb out cable and reconnected using the lnb 2 to the tv, but tv AND humax reported no signal.
THEN the signal returned to the tv next day, only to disappear
Currently have freesat working on the tv using the original lnblater.2 cable (works now, don't know why) and my intention is to leave this as is , leave lnb1 connected on the humax, and loop lnb2 from lnb out. Unfortunately was up to my t**s today so no developments to report

Peter Rhea

Are you using the twist-on f-connectors? In some cases, if the connector isn't a particularly tight fit on the cable & you don't watch what you're doing, you can undo the connector body from the cable, while tightening the nut.

For the loop ill be using a cable bought in power city, otherwise connects are twist on but did the job til the arrival of the new tv, and the one to the tv was fine for a while. Thanks for the suggestions!

Powercity cables are terrible quailty. Some of them use a centre conductor so thin it won't make contact with the receiver properly. I would not recommend using them for satellite use. If you are using one and having problems this may be the cause.

They'll do the job just fine, provided they're a good fit for the cable, they're fitted correctly to begin with & they remain so. Intermittent operation could be a result of the centre conductor becoming withdrawn from the connection on the receiver as the one on the cable is inadvertently twisted off while screwing it onto the receiver female connection.

ActingDanClark

thanks. however all i did was unscrew lnb 2 and connect it to the tv,which is now working fine apparently. humax wont be approached til tomorrow as im on the road

Peter Rhea

If you moved the Humax receiver to get at the connectors, it might have been enough to upset the LNB1-in connection if it wasn't great to begin with.

I don't want to keep banging on about it, the point I'm trying to make is that most of these faults are caused by fairly mundane things, dodgy connections being one of the most common.

ActingDanClark

Didnt feel you were, that Saud, even if that were the
case, I don't understand how lnb2 cable didnt supply
a constant service to the tv freesat tuner. I'll check the
connects though, thanks

ActingDanClark

Didas I said I would having left the humax unplugged for a few days, checked the lnb1 connect, did the biz and everything works having formatted the humax.
Thanks all for your contributions and advice
