No Signal issues Openbox s10

I hate these "My dick is bigger than your dick threads " :(
Seems to be a few of them on the forum recently

i hate the wrong info being spread about these sites as cardsharing can be hard enough to do for some people with the correct info.
 
what info is wrong slybox ? that openboxes have a problem with sky lnb's ? that filters can help in some cases ?
or something else
 
OK lets get to the problem, has any member got one of these receivers and a multimeter? I would like to know the voltage readings when a vertical transponder is selected (should be ~12v dc) and the reading when a horizontal transponder is selected (should be ~18v dc).
With the circuit shown the 100pf capacitor will be a short circuit at the frequencies concerned but although the diode will drop ~0.6v I dont like this fix, far better would be to correct the receivers circuitry so that the correct voltages are sent to the LNB.
If the voltages are high then the receivers should be returned to the dealers along with a letter detailing the fault.
Guys lets not start name calling lets get to the bottom of the problem but also remember their are con men out there.
 
i thought the same mate people making a killing selling these at a £10 a pop on ebay is ripping the ass a little but when a mate of mine got one from the supplier he got the openbox from
and it worked i was shocked . thats all i can say on it i didnt open the box on his and got the pic from else where after looking into it
but will get him to post his findings and a couple a pics of the device . maybe he wont get shot down in flames like i have :p

all i can say is i have seen it cure signal problem and cant say whats in the little device but will get pics posted by the member that owns it
i wouldnt say its a better fix than ditching the sky crap but i can say it worked for him.
and no i aint selling them or saying anyone should get one but for £3 he paid it saved us putting up a second dish

hello
jimi

have a s11 at home and s9 at girlfriends house but my multimeter is at work, will test them tomorrow and put my findings hear.
hope this helps

hears wots in it: Specifications
Military/High-Rel:NV(Z) Nom.(V) Reference Voltage:7.5@I(Z) (A) (Test Condition):335mTolerance (%):10P(D) Max. (W):10Z(z) Max. (ê) Dyn. Imped.:1.3Maximum Operating Temp (øC):175Package Style:DO-4Mounting Style:TPulsed Measurementæ


notic the dyn. imped it says 1.3, that means that the diode cut's the voltage buy 1.3 volts
im only hear to help people and get help, im not hear to argu with you, im trying to help you and others as others are reading this, that have the same problem and need to know how to fix it.
hope this helps
 
seems to back up what i said then drops the higher voltage kicked out be openbox to an acceptable level
 
Please can someone post the item number as I want to see exactly what is going on. I cannot imagine that a receiver manufacture would have the LNB switching voltages out by either 0.6 or 1.3 volts. The modification at the best would be a bodge and I dont like those. Can anyone give the specifications of the SKY LNB or is any member using these receivers with another brand of twin or quad LNB without problems?
 
when I had my first S9 if I connected it too one feed and my official sky box to the same dish through the second feed of the sky LNB the S9 would only receive low band frequencies if I turned the sky box off the S9 received all frequencies I replaced the LNB with a different sky LNB purchased from digidude and it cured the problem both boxex would then receive all frequencies so I would say that some sky LNB's are not compatible with S9's

I see the same problem was talked about about a year and a half ago see this thread https://www.digitalworldz.co.uk/index.php?threads/267860/
As manic01 posted in that thread it seems to be an S10/LNB problem we will know more when the voltages are measured.

hello
jimi

just a quick post on voltage reading as playing cards tonight.
was only able to test my s11 as have no time but hears the readings: horizontal low = 19.61v to high
vertical low = 14.54 ok
horizontal high = 19.63 to high
vertical high = 14.46 ok

as you can see the box is putting out to much voltage on horizontal high & low. imo the old sky quad lnb's cant hadle the extra voltage and outher lnbs like inverto/icyptd can.
will dig out the lnb that gave me the truble and give readings from Spectrum analyzer and will get readings from s9 IF NEEDED? but think you can see the problem.
hope this helps

My S9 was producing too high a voltage to switch my LNB. I looked at the main board with a view to doing a 'proper' solution to the problem by changing a dropper resistor. I found as to be expected that SMD's appeared to be involved in the LNB voltages. I am not competent to work with SMD's so I contacted my supplier who accepted that there was a fault. However I would still have the cost of returning the GBP60 box and the hassle involved so found the voltage dropped by a diode worked for me. There was no capacitor involved so can only guess someone had a 22kHz band switching problem with the diode by itself so put in the bypass.

What does not help is that the threshold V/H voltages are not always stated in the LNB specs - as an example one full spec gives 11v-14v for V and 16-20 for H.
 
in another thread about the varistor I found that to be a handy spot to measure the voltage out of the box with the lnb hooked up as a load.On a fixed dish I have no problem with a universal lnb but on a motorized setup it's a pain to tweak the dish.I have to switch from a V tp to an H then back again to get a signal quality reading.So I just use the universal for my fixed dish.I didn't try any other firmware to see if other manufacturers (opticum or manhattan) have the same problem.
 
Just the the diode on the feed I was having issues with and voila all channels workin. No issues with No Signal :)
