As of yesterday, I have suddenly lost all four Freeview HD channels,with each of them displaying 'No Signal' when selected. The Freeview HD tuner is built into the TV set, not a separate box. Analogue and digital SD reception fine. Aerial sited on roof.
I wonder if there is a problem in my area,or could my set be at fault?

Like Mr Poulton, I too lost Freeview HD signal on Friday 20th Jan from about 21:05 to 21:55.
Freeview SD was unaffected, continuing with 60% signal strength.
This was experienced both by the tuner in my Humax Freeview HD box and built in tuner on Samsung TV.
Aerial is on the roof. Location: Uxbridge

I have new TV with a built in Freeview HD receiver but as yet cannot get HD channels. My transmitter is Crystal Palace and i believe the power level is low from the HD mux. Is this so and will it be increased when digital changeover occurs?
I live in St Pauls Cray

Ron Knight: Yes, the power of the HD services from Crystal Palace will be increased when switchover occurs.
HD services are not part of the standard offering before switchover. Crystal Palace is one of four transmitters that were chosen to carry it before switchover though.
The current HD service is lower power than the current pre-switchover standard definition services (which are on lower power than they will be come switchover).
Try manually tuning to Ch31 for HD services from Crystal Palace now.

I appear to have a "single frequency interference" problem covering the ITV1 etc multiplex which began on Thursday 17th Jan. I have a Humax PVR-9300T freeview box and a roof ariel directed towards Crystal Palace. I have followed the instructions to clear all channels on the box and reset but am unable to reconnect the ITV1 multiplex. On the TV in the bedroom with integrated Freeview the same channels are black. Please help if poss.
