tuner lock help

[john doe]

I've recently bought a os mini single sat tuner for a spare room. in another room I have two feeds going into living room & two upstairs (4 feeds from LNB). in the upstairs room with the 2 feeds. i have taken one cable and taken over to the spare room, I had to buy a RG6 Satellite cable extension to reach (came already fitted with the F connecter and joining barrel).

the issue I get on the os mini is tuner lock, aslo on the other box upstairs (vu zero) if the os mini is switched on, the channels break up (plays for second and goes to black screen with no picture). if I switch the os mini off the other box (vu zero) works fine. but no picture on the OS mini.

I know it not a single issues. am missing something. do I need to swop the cables around? I hope not, as I 've pinned the cable to wall.

1. what happens if you connect to the Vu out?

1. what happens if you go from the Vu out direct to the Edision? Bypassing the extender?

same issue tuner failed.

[john doe]

same issue tuner failed.

I've just noticed that the os mini tuner A is showing in red

[john doe]

also the zero is now working all channel, even if the os mini is on, but still no picture on the os

[john doe]

anyone!! any suggestions

Draw a diagram. Include any splitters/combiners

How are you expecting a picture if the receiver is powered off?

[john doe]

the receiver is powered on but no picture.

can you elaborate in regards to draw diagram

[abu baniaz]

Please ignore my post.

[john doe]

would I need a splitter? and if so what splitter.

[john doe]

SORTED IT I had to change the feeds around from the zero to the os mini and vise vera.

You can't simply split a cable feed from an LNB and share it between two receivers. If you have both powered on they will conflict for control of the LNB depending on what channel you tune to. There are different voltages and signalling tomes sent up the cable to the LNB depending on whether you are tuned to a Vertically or Horizontally polarised transponder.

You need either more cable runs from the LNB (an octo rather than a quad) or you need to invest in a quattro LNB and a multiswitch.

thanks. it works fine and can watch different channels at same time and two different receivers with no issues. it was basically down to swopping the feeds around
