I've just got the above box to replace the outgoing skybox. On the sky box it says I have 90% on signal and quality on both inputs and I've never had a problem. I've just tried several times to install the humax but it says I have no signal. I've checked the f-connectors are on correctly etc but it made no difference. Am I doing something wrong? Is there a certain order I have plug it all in? Any pointers would be great.
