My in laws have run a cable up stairs to carry the HD Sky up stairs (coax), when attatching a tv link to it, the link does not work, and the picture drops to about 20 percent quality, any ideas?
Carefully check the connectors on each end of the cable for shorts. If even one thin strand of the braid is touching the central core then the RF2 output voltage will automatically turn of to prevent damage.
The thing is the signal of the pciture carries perfeect upstairs, but as soon as you connect the tv link it drops signal, and the link doesnt work (it is not a faulty tv link, I have checked)
Chek the instructions fully, although there is an option to turn off and on the rf2 output there is also a power up option which will enable the remote functions and tv picture to work.
Connect the TV link and then go back into the Sky box menu to ensure the "RF outlet power supply" setting is still enabled. If the box is at all unhappy with what's connected to RF2 then it will turn the power off to prevent damage.
You select this setting by pressing "services" then 4 then 0 then 1 then "select" this takes you to the Installer Set-up page where the setting can be accessed (item 4, RF Outlets).
