loop through working but no Sky output

[markspraggins]

Hi. Thomson DSI 4101 went mad and wouldn't switch on. Eventually got it working but now terrestrial signals loop through but can only get Sky through scart. So to confirm aerial in to Thomson and out to distribution through RF1 gives all terrestrial channels with a good signal.... but no Sky. Tried changing channels from 68 but no luck. Anyone seen this before please. Thanks

From 68 to what? Hopefully the frequency that the Sky box is outputting its analogue signal on?

Try disconnecting the TV aerial from RF in - if you are in the process of DSO, your terrestrial signals could be being changed, and you may find that a digital MUX is now broadcasting on the same terrestrial frequency that your Sky box is outputting on. Removing the TV aerial from the equation - so that the only signal being sent via the RF connection is the Sky box analogue output - should remove this possibility.

thanks Broadz. Yep - tested with no aerial in the RF in. Same problem - absolutely no signal. It just feels that somewher along the line the Sky feed to the RF is not working

Welcome to AVF.
RF1 Out is for the main TV which you don't need as you have the better Scart, and it's RF2 Out that's intended for "distribution" to other TVs.

Or your TV is not using it's analogue tuner.
When you say you receive all the "terrestrial channels" is that Freeview or the 5 analogue ones?
