Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That sounds as if the ultimate source for the TV signal that is to go from the digisender to your Samsung TV, is not present. What TV service do you have, actually, that is supplying the digisender (and the Samsung TV via the digisender) ?
OK. But the Sky service must be lacking, then. Check the Sky box, for its status lights.
If you will, if all looks 'normal' on the Sky box, then unplug it.
And wait 5 minutes.
Then after that much time (or longer) plug the Sky box back in.
Wait 2 minutes.
See if the Digisender is now working, then see if the TV is working.
Let me know how it goes and what you see, so that I can advise you further or - if it is a success, what I recommended to you, so that I can close this case. Thanks.
Check the connection from Sky box to Digisender, then. Re-seat cables, what cables are involved.
HDMI Cables can be bad (esp. if cheap) or go bad.
Do you have a spare? or can you swap cables with each other at least?
OK, then. Digisender is complaining about no signal source.
Defective HDMI cables eliminated (hopefully) as cause, because swapped out, and re-seated too.
Sky box has been turned Off for a while. (After swapping cables you might need to power the Sky box off for 5 minutes again, and try it again. Swapping cables can upset a system, after all. Some power-down time again might help at this point.)
If you swapped the HDMI cables since then - yes!
Also power down the Digisender for 5 minutes... the TV isn't of much moment at the moment, so it can stay On.
That's a shame!
Well, we got it to the point where there are two possible interpretations left (aside from the odd possible case where *both* HDMI cables are defective... unlikely of course...):
1. you have a defective Digisender.
2. your Sky service is down.
I advise you to check on your Sky service, by calling Sky, asking them to verify that there is no service outage and your account is in good shape. (I hope I'm not talking nonsense here... I am presuming that Sky service is not just 'its taken out of the air its free' service. That it has a status and a company to call and so forth.)
If Sky service is not down, you probably have a defective Digisender I would guess. The light on the Sky box is green, after all. (Maybe that's just the box, not the Sky service itself, that is indicated as to its status.)
If the Sky service *is* down for now, you need to (have Sky) get it Up and Running again.
I see the case this way. If you have anything else to mention about the situation that might change my opnion, let me know, please.
(And, If this answers the whole problem/question of course, then please rate my answer if that's how it is.)
Check the Sky service too (unless it's a free-service and no company and no account of yours to access it etc.)
That sounds sensible. We've done just about everything else that could be needed, I think.
If you're done with the case, please rate my work and my answer(s). Thanks. Good luck!
That's fair - come back to this case once your sure how it went and have the full context of my work and my opinions and estimations of the situation etc. etc.... at this web page:
Thanks. Good luck. Enjoy your Sunday (international date line time zones permitting.)
