Loss of bbc1dvb after scanning panasonic tx-28dt4

Hi,
BBC1 and BBC2 are among the strongest signals you could simply have a low signal reception, try a channel dump and re scan for all digital signals, try re tuning on a different aerial if that's possible. If all this proves fruitless the fault will most likely be on the Main AV Panel where the tuner an IF stages are found. Post your Brand and Model Number for more specific help suggestions

You might have more than one transmitter. Some TV's etc only store a certain number of channels and have a max amount!. When weaker transmitters are present sometimes the memory of the TV will only store the stronger signals first from these weaker sites, with the two BBC channels being too weak to be detected.
The solution is to do a manual search on the transmitters you know are very strong. For example if channel 43 has strong signal you would search on that. The auto search will start at 21 and work it's way to 69. But if your area transmitter with the strongest signals is high up the scale the weaker transmitters will be selected first!

So you think I'm gonna answer my own question then tell you how I did it, so that you can then CHARGE someone else for MY answer?! I don't think so! An excellent 'service' you have here - I DON'T think.

Make sure that you do a new install retune not an update the channels have moved around a lot

Make sure all cables are securely connected to your Freeview Box or Freeview TV before you begin

Do a Factory Reset of your Freeview TV and then do a rescan of new channels. If successfull then all channels should be back and working.

try re scanning your channels, happening a bit at moment because of switch from analogue for bbc etc

I have solved the problem by selecting Manual Tune in the Menu. This means selecting each channel one at a time beginning at 21. The indicator shows the Signal Strength and Quality for each channel. If both show a green bar (strong on both counts) give it time to identify the new programs on each channel and add them. It will show how many found and added if you wait a few minutes. When each channel is done, move on to the next one. The last channel is 65 I believe but there is not much up the top end.
When I had finished going through this routine I found it had indeed added all channels I needed including BBC1 and BBC2

I have contacted Panasonic, they are aware of the problem and will post you an update card to correct the fault.

I have the same box and re-tuned mine with the same results as you.However i discovered that the NEW BBC channels were on the channel guide list starting at channel 800
