Freeview is attached via the aerial socket. There are no messages displayed on the screen with the exception of 'SKY' or 'Freeview' in the top left hand corner. If I switch to the Blu-ray input (HDMI) 'DVD' is displayed in the top left hand corner and 'No Signal' in the centre of the screen. (I would expect this as the Blu-ray was switched off. The reason for the late reply is that your web server was down yesterday.
Everything was switched off at the wall socket. The hdmi cables were removed (SKY and DVD). The SKY card was also removed. The system was switched off for at least 10 minutes. Even with the HDMI cables removed no signal was detected through the AV socket (Freeview). I was able to access the TV menu and with the aid of the TV manual check every option available. For some unknown reason the system seems to have rectified itself as it now works as expected. However, I still wish to know what caused the problem. It seems that it is a software issue as the TV seems to think there is still an input from a disconnected HDMI port hence not allowing input from the AV input.
I've just checked the firmware version on the TV and according to the link you sent me it is the current version (ver 1.267). As I'm paranoid I check for software updates on a fairly regular basis. It would seem that the problem I have was not addressed on that update. Where do we go from here?
The TV has an inbuilt freeview tuner. The aerial plugs into the AV socket at the rear of the set. Under normal circumstances this works fine. It's just a case of selecting the AV socket as the input port.
Strangely enough I considered resetting the TV to it's Factory settings and as you can imagine I was reluctant to do that due to the amount of setup required for the added components. However, if the problem reoccurs that would seem to be the only option. At least it might solve the lip-sync problems too!
I have sold Panasonic Toughbooks (Laptops) to the MOD for nearly 20 years. In my experience once a product has been replaced by an updated version they are no longer interested. I can only assume they have the same strategy with their consumer products which probably explains their current financial problems. It's a shame as they can (on occasions) produce some really good stuff!
