Tune failed message keeps appearing.

Try and figure this out.

I had a 3rd spare coax running in the room but not being used. Running from same lnb as the other 2. It was coiled up not being used. So I uncoiled it and plugged it in one of the tuners. Instantly got picture again. And both tuners are showing signal.

What's going on?

That could be a sign that either the two feeds you were using are damaged in some way or that your LNB is on its way out or both. you need to check the cable runs and all f-plugs to make sure they are in good working order and maybe get that LNB checked out or replaced all together.

How easy is it to replace an lnb? It's not expensive for a new one.

On a sky dish it's just a matter of one screw usually on the collar of the LNB or the bracket holding it to the arm. a new LNB for one is just a few quid but make sure you get the rite one.

 

[Martincape]

How do I know which one I need pal?

 

[Larry-G]

you would need to identify the dish type but most will come with a couple of different collar types any way, you just use the correct collar for the dish and throw the old one.

It seems spot on now pal. The spare cabe I plugged in seems to have helped. Could the one I was using have been degraded and caused the blackout? As I still have 2 cables plugged into solo with good signal strength.

Yes .

Defo a problem with your other 2 cables then buddy. I would snip a couple inches off n re connect. But be sure to use proper tape n not insulation tape.

Each port on LNB is in essence an individual LNB. It is possible that the one previoulsy being used is faulty and cable is fine. If you swap the cables around at LNB you will know whether it was cable or port on LNB.

Cable A. Untouched cable still coneected to receiver.
Cable B. The one that has been disconnected.
Cable C. The cable that has been uncoiled.

Swap cables B & C around.

Thank you for all your help. Still hasn't failed since I swapped over. So it could be a faulty lnb port. I'll swap cables over at the dish tomorrow and see what happens. It's a quad lnb so I can afford to lose two lol

What's proper tape pal? I thought insulation tape would be ideal.

 

[abu baniaz]

Amalgamating tape. It's rubber and sticks to itself. But you shouldn't need it if you pull the hood down.

Don't use insulating tape (PVC tape). What you want is self-amalgamating tape, which is a form of rubber tape (not sticky) which you stretch as you wrap around the F connector on the LNB. It forms a watertight seal and moulds to the connector. Works well on single and twin LNBs, but is a bit tricky on quads and octos due to the limited spacing between the connectors, but it can be done. Alternatively, purchase some rubber boots for the cable and put some silicone grease (not silicone sealant!) on the cable end and over the F connector before you slide the boot on.
