Since digital switchover i cannot recieve bbc1/bbc2

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!

This This is a difficult one . You may have to go online to get an Upgrade for the TV..You will need a flash drive and of course there must be a USB socket on your tv... Other than that im stumped. Sorry.
hope this helps

Could only get bbc1 london,wales, scotland, or northern ireland. Could not get bbc1 south.

Try other nearby post codes, tried 3 or 4 then eventually hit on one that worked . (Bournemouth area)

cant get bbc1and bbc2 on the hitachi digital television fter retunining it

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.

sounds like power surge. try unplugging unit from wall. wait 2 minutes. this reset the microprocessor in the tv. plug back in and enjoy!

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.

I also have the Sony IDTV KD-28DX4OU Digital TV.After the digital switchover I lost BBC1 and BBC2 despite retuning three times.
I contacted Digital switchover people (useless) and they passed the buck to Sony.I contacted Sony and they said they cannot fix the problem and that I should get a digital set top box. So the £650 I spent on integrated Digital TV has been wasted.If like me your cheesed off with this then I suggest you complain here

I have

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

Are you in the UK? Is the new DVD player compatible with TV in your area?

Some technical details like make and model would be helpful.
