You may lose some channels when you retune the TV as the channels have been rearranged. To locate them look at the EPG although you may still find that some channels are no longer available on FREEVIEW. See the following link for additional information

If the above process does not work then check the link above for additional information and also visit the accompanying site links below to find more information for your model of TV / FREEVIEW box.

The official line on this is that you should try and retune again, but there are some Panasonic models with similar model numbers to yours which have been specifically identified as having incompatibility problems with the Freeview retune.
However, your model is definitely not one which appears on the problem list, so it's worth checking that your aerial wasn't misaligned or damaged during the gales last weekend. In addition the Winter Hill transmitter is currently undergoing work until December which will significantly boost the digital signal and give it HDTV capability, so your box may have have been knocked out of kilter if the current digital service was temporarily operating at restricted capacity. Digital signals are by their nature much weaker than analogue tv and if you have a marginal aerial system which has been up for many years and which feeds a number of televisions in the house then it's definitely a good idea to see about upgrading your aerial system.
The difference in actual parts costs between a top spec aerial system and a poor one are surprisingly low, it's also easily possible with careful design and installation to get a better performance with poor parts than you can get with a poorly designed and installed system using top quality parts. One thing does hold true though: a well designed and installed system using poor parts will only last a few years before needing serious attention but a proper job can last up to thirty years.
If you're sure about your aerial system and retuning does not help, then you'll need to contact Panasonic directly. The first web address below will give you their contact number along with a list of Freeview boxes with known retune issues. A second web address which I've given takes you to an excellent Sheffield based tv aerial company which has an incredibly informative website.

Sounds like you haven't retuned the set correctly. Use the factory settings/ default setting if poss. Look out for too much signal if you are on a booster.

When TV channels are moved from one frequency to another frequency that was previously used by a different channel (sorry, but there's no simple way of saying that !) as has happened recently in th UK, some digital TVs and digiboxes struggle to sort the channel list out properly and channels can go missing as you describe.
If your equipment has the option to delete all currently stored channels (normally in the tuning menu options) then do so and then do a full re-tune.
Sometimes, this solves the problem as the equipment is no longer aware of any previous use of a frequency and just loads every channel it finds.
If this doesnt work, or your equipment doesnt have the option, then there is normally the option soemwhere in the menus to retore the item to "factory defaults/configuration". This will clear all previously stored channels and after a full re-tune your missing chanels should be there. However, any other configuration changes you previously made, e.g picture size, output type (RGB/NSCT/etc), etc will be lost and you'll need to set these again.
NB. some regions of the country have lost some channels temporarily now until after the switch over programme completes at the end of 2012. If you visit the Freeview website, this will tell you if your area is affected.
