Mrs Pearce: I would have a look at Freeview reception has changed? | ukfree.tv - independent free digital TV advice as there is no transmitter problems reported at the moment.

Thanks for the replies jb38 and Briantist. I'm getting asked a lot of questions re the switchover at work.

Can I ask one more?

I'v heard that some devices at switchover will prompt for a re-tune?

i.e Click OK to reset your TV and perform a full system reset.

If this is true, do you know where I could find a list of devices that will do this?

Regards

My freeview stopped working on Sunday. The picture on all of the freeview channels is very bright.

The picture is fine with the analogue channels and with movies played through a PC.

What could be causing this?

My postcode is SW9 9PE

Aerial Point: I don't think such a list exists. The changes to allow boxes to auto retune at switchover was added to the specification for Freeview (the so-called D-Book) quite some years ago.

Adrian: It is most likely the SCART cable that connects your Freeview box to the set. Remove it from both devices and then reconnect it firmly.

Aerial Point: Just to confirm / back up Briantist's reply to your query insomuch that this is quite correct there isn't any list, and with so many variations in the menu facilities offered between the various brands (and sometimes across different models within) from basic primitive to quite sophisticated its not practical to make a note of them.

Hello,

Recently moved into a new flat, and it picks up every single SD channel fine, however, it struggles with the HD channels.

When I first tuned it in the day time, it picked them all up, and the signal/quality were both strong. However, as soon as it got dark, it lost all signal/quality.

I have since retuned all channels, and it won't pick up any HD channels at all. Doing a signal check on channel 31 in the Manual install option gives 0% Signal and 0% quality, however every other frequency channel is around 70% signal, 100% quality.

Any ideas? Using a Humax HDR-FOX T2.

THanks all

Alex: Although the Crystal Palace signal on C31 is predicted to offer reasonable odds on giving good reception on the HD services, the signal is at risk of interference from both Sandy Heath and Reigate at your location. When retuning at a time of receiving a poor quality signal (or no signal) the details of the HD channels would have been removed from the receiver's memory. Wait until 18th April 2012 for the high power HD service to start at Crystal Palace, otherwise, until that date keep looking at doing a manual tune on C31 to see if the low power signal has returned.
