Wireless AV Setup Bollocks

My dad wants a TV in the kitchen but we have no aerials etc so we've bought a wireless AV transmitter.

Trying to put it as simply as I can, these little transmitters have composite inputs (red yellow and white) and the Sky box I'm trying to wire it up to only has SCART sockets. So, as you would do, I decided to use one of those little SCART to Composite converters like you get with games consoles - suddenly, I'm getting to picture.

I then go from connecting different Sky and Freeview boxes with a similar setup but straight into a TV rather than a transmitter and, unless I use a Scart to Scart lead, nothing appears.

Is this the day the world has decided to void the usage of Composite cables, or is there something I can do about this? Many thanks.

Sounds like you've either got a crossover where you need a straight or a straight where you need a crossover.

A Sky box will usually be set to output RGB rather than composite video on the main scart socket. Try using the secondary scart (which I think has to output composite video to allow for recording to a VCR?).

Alternatively, go into the picture settings and turn off RGB output to see if this makes it work (albeit at the expense of picture quality on the directly-connected set).

I've tried both of these and neither have worked. The VCR output doesn't work at all, even with a Scart, and the TV output refuses to work when a Composite is in sight, and either RGB or PAL will bring a picture up on the settings.

I'm pretty sure that Sky boxes refuse to work with composite, but even connecting the audio jacks doesn't produce any sound to the other end.

Sorry for the late post. I came across a Scart lead with a switch and it works fine. However, I'm getting a dodgy signal on the other end of the transmitter (either fuzzy audio or a flickery picture) Furthermore, it's badly effecting my wireless router. Any advice? :)

2.4GHz is a busy band, it might explain both. Getting a 5GHz router would solve the problem, or a 5GHz video sender if such things exist

The fuzzy audio / flickering picture will be your wireless router interfering with the video sender.

You can try changing channels on your router or video sender (if it has that option), otherwise you will need to replace one of them. If your neighbours have equipment on the same frequencies you may not be able to find a clear channel to transmit on though.
