holburn,
I have joined today because I am concerned that you are being misunderstood and, like all of the people here, am keen to get you up and running with your system.
However, I am also aware that I may have completely misread your posts and got the wrong end of the stick.
My confusion arises because you use the words "signal" and TV together which, immediately, to me means the aerial signal. And yet you refer to the HDMI and SCART cables, which do have signals but of a different nature.
So, please, can you help me - just one more time - with a few simple questions. I apologise if that is frustrating and I am teaching you to suck eggs.
1. Can you confirm that you have a aerial coax cable from your aerial wall socket to your Humax aerial input and also one from the Humax aerial output to the TV.
2. Can you confirm you have connected the HDMI cable from the HUMAX HDMI socket to an HDMI socket on your TV.
3. With the Humax switched on and yout TV's input switched to the HDMI socket that the Humax is connected to, do you get a picture?
4. If you do not, is the lack of a picture the problem? If so can you press the V-Format button on the remote to cycle through the HDMI output resolutions.
5. If you do receive a picture, can you switch to your TV's own Tuner. Do you receive a picture?
6. If you don't, is that your problem?
7. If you do have a picture using the TV's internal Tuner, please swich off the Humax. Do you still receive a TV picture form the TV's internal Tuner?
8. If you do not receive a picture, is that your problem?
Please can you answer Yes/No alongside each number. this wil help to resolve your problem and, perhaps, save the aggravation of returning the box.
