Hi there

We recently bought a new Teac LEDV2420DT Tv for our caravan. I had trouble setting up initially but thought I was just struggling with the caravans satellite dish.

However I bought the TV inside and plugged in the satellite cable from our Freeview box and get absolutely nothing!

I have tried scrolling through the preset LNB settings and re-scanning but nothing. The quality bar shows nothing

Any ideas?? I have spent hours trying to fix this!! Any ideas would be greatly appreciated

Is there an option for LNB power?


Sounds as if the TV is not powering up the LNB.


EDIT: I've just checked the manual, so long as you are choosing Optus D1 as per the manual, it should pick it up on your house dish (there is the option to change the frequency from 11300 to 10750 to try that though). It should be preconfigured for LNB power.


Just double checking that you are tuning using Satellite settings, not DVB-T?

TVs do not have built in satellite freeview.


they have UHF / terrestrial freeview. You don't need a dish you need a UHF aerial




ok sorry, foot in mouth. I see that TV does. my bad

I have no experience of this TV but I am looking at the user manual. 


One thing that I ran into with a completely different unit was a faulty country setting. It might be worth trying the other countries just to see if anything comes up on the scan.


Changing the LNB frequency is definitely worthwhile. The default appears to be 11300 but 10750 seems to be more common these days. As the manual suggests, try all available frequencies. If nothing seems to work, put it back to 11300 unless you know for certain what your LNB uses.


Your set-ups should not be using a DISEqC switch so that should be off. But you never know so you could try running through the options for DISEqC 1.0.


Check settings as advised above. That is all I can think of.

I suspect it's the power requirements for the LNB (Quad supplied by Sky I think).


If I try to power the sky dish from the TV I get no satellite signal, nor do I get a signal if I try to power the dish from my Matchmaster Multiswitch, It seems I can only power the sky dish from the Sky STB.


Although there does not appear to be much of a voltage difference between the Sky STB (18.52v) and the multiswitch (18.12v) so I don't know why it does not work.
