F5s No Signal all channels

[andylad]

Hi can some help , this is driving me crazy, I have an F5s downstairs ,f5 in one bedroom & very recently purchased 5fs in second bedroom all running off quad lnb(ex sky kit)

for some reason since I purchased the 3rd box , I get no signal on all channels on latest box, this has also passed on to box in other bedroom. If I unplug one of the box's & leave for an hour , it works fine, however it would seem I'm unable to use 3 box's at same time. I'm looking to purchase a forth box but as you can see I'm struggling . Any help pointers would be a great, thanks. Andy

Hi sound like a drop in the signal power...
are you running 3 cables from the LNB one to each box.....

LNB could be faulty or you need a signal booster

the sky box f5 is known for this they drain the lnb power

You can either go down the route of fitting the skybox LNB fixes that they sell on ebay:

No Signal Fix s9 s10 s11 s12 F3 F5 V Polarized channel selection Openbox Skybox | eBay

Or the better option of replacing the LNB, I know the Zinwell (J4L) model works perfectly with 4 Skyboxes. So anything after that model should work fine as well

Thanks people, its not the no signal fix as its all channels not working when I power up 3 box's, for the sake of ?5 I'll order a new lnb ,

ill let you know, really appreciate your responses

I have 3 feeds from my LNB..1 to the F5 and 2 to my Sky HD+ box...mine works fine so does sound like your LNB could have died

genam i will give you 10/1 you stick another F5 on your setup & you'll get the same probs
the F5's drain the power so much from the lnb its frighting

Quick suggestion, would an amplifier not work?

Yes i know it costs a similar amount but another person who reads this with this sort of issue may have an amplifier lying around (like i do )
