Video sender?

Do any of you guys use wireless video senders?

I bought a new set up so i could transmit the skybox downstairs to the tv upstairs in the bedroom and couldnt get it to work and now the receiver doesnt even turn on so its going back. So i tried an old system ive had for years, but forgot all about it, til i found it in my loft.

Both the transmitter and receiver light up, but doesnt matter which channels i put them on, i get no signal or audio to the tv in the bedroom.

I have had to use scart out the skybox to the transmitter and scart into my tv upstairs from the receiver, ive even tried swapping the units thinking i had them the wrong way round, but still nothing.

Any help appreciated, cheers :thumbup1:
