Hi

I have seen this mentioned before but have never fallen to this issue until now.

I had two openbox s10 both connected to a sky quad lnb. both working fine.

Updated the channel list on both boxes. One work fine and other one has no signal issues.

Now to elimate issue with box i tried the box that was working on the feed that wasnt and that also started having no signal issues.

Alot of solution have been mentioned from diode fixes to inline amplifiers.

What would do you recommend as a process of elimination to solve this issue

Forget any mention of diodes as your problem is either the LNB or the down lead or F connectors. If one line from the LNB works then try the NON working receiver on that line if that works then you've proved both receivers are ok. You could even connect the dead down lead to the known working section of the LNB if it works the you've proved the fault is with the LNB if it dont then it's the lead or F connectors.

its not the openbox its the way that both boxes act on the lnb that the problem. i have seen this problem a few times.
do both boxes work fine if just 1 connected to lnb and your getting the problem when you try attach both to the lnb ?
or are you saying that both boxes work on 1 feed and not the other ?
 
It is when one attahced to one LNB.

The feed tht is workin both boxes work fine. The feed tht doesnt wirk both boxes dont work.

Now what i dont get is when the guy who got these boxes first put them
in he had no issues with both boxes working fine and now this feed seems to be playing up.

Any solutions suggestions???

I hav reflashed images tried differrnt channels lists to no avail.

What about on fleaby there are these no signal fxes what are they exactly??
 
the ebay fixes are

Brand new lnb put on a week ago.

What do u mean shorting cable??
 
Just an update guys

plugged a skybox f3 into same feed that i was having issues with no signal and all channels working perfect no issues.

mate has bought one them diode fixes from fleabay and once it comes i will post back with results.

the diode fix is a mith ( bullshit ) the problem as jimi said is with your lnb, ill bet your using a sky quad lnb, the problem is the lnb is not switching properly ( openbox's arnt very good at swithing from horizontal to vertial with some lnbs ) Polarisation switching is controlled by DC voltage supplied by the receiver. 12.5v to 14.5v gives vertical and 15.5 to 18v gives horizontal polarisation. A higher voltage than that can damage the LNB. A voltage that is too low will prevent the LNB from working correctly, change your lnb to a inverto or icecrypt and your problem is solved, trust me i do this for a living.

I cannot leave this statement unchallenged. It is not a 'mith' (sic).

As far as I am aware I did the first fix using a diode to drop the voltage (about 0.5v) as my S9 was not getting the vertical TP's.

The single LNB was not changed as it worked satisfactorily with all other receivers.

Having said that some receivers (including Openbox) do have problems with multiple feed LNB's.
 
from what i know it does work as the openbox pushes out a good voltage and the basic sky lnb's just cannt handle the little more juice that it gives out
saying that i have only ever seen this problem with 2 boxes conected to the lnb
 
Wha i dont get it if it was an LNB issue then why is the Skybox F3 working on the same feed and LNB ??

Thoughts.

you's seem to know it all lol so no point in me trying to help you, iv only been working at sats for over 10 years
peace out
 
i or no one else is saying we know it all slyboxhd but all i can say is i and respected member of the site spent a week trying all sorts to sort his dish
he has a dm 500,dm600 and dm800 and a spare feed for testing . as soon as we put a openbox on the spare feed the dm500 and openbox couldnt get a signal
we changed the lnb from a octo to a quad and tried again same results . put an new octo on and still the same
we added filter that he picked up for a couple a quid and job done all 4 boxes would clear
so i dont really care if you have never came accross this before as i have and got it solved with filter on the openbox feed
i cant say for sure this is the problem here but after trying another box on the feed and it clearing signal ok its my guess

oh and i also been dealing with sat for years doesnt mean i know it all . like you seem to think about yourself
 
Lol. Lets play nice boyz :)

I am hoping to try the fix tmz as well and will post back to see if work.

Thanks for advice guys :)

i dont think i know it all but have been trained buy cai and know that if you need a diode added to a lnb fed there is somthing wrong with the lnb or the satbox is no compatable with said lnb.
if you where trained like i have been you would know that.
END OF
 
maybe the ground on the lnb isn't really earth ground,so 1 receiver would interfere with another.
The coax should be earth grounded with said grounding block where the coax comes into the house.
Also,it must be a universal lnb problem because standard ku linear lnbs work fine if you can get away with it.
I have no low freq transponders(below 11700)so I use standard ku linear.
 
ye i have not been trained in anything to do with sat just a hobby but i have fitted lots a boxes an dishes and only ever had this problem with openboxes and multi feeds
all on cheap sky lnb's . yes it would be the pro way to fit new lnb and spend more cash to fix a problem but there is a problem with openboxes on multi feeds
and i have seen these filters work and in a respected member of this forum house
i at first got him to try everything we could think of and it was him that called my to say it was sorted with a stupid 3 quid filter from the market
i dont care what training you have had i wouldnt be up no ladder if a £3 filter would do the job
