How to get a perfect picture for my PANASONIC VIERA SMART LED 3D TV.

You need to select setup from the TV menu then switch the Viera link on. I think retuning must have switched it off.
This worked for me

You need to (either or both) change from Shop setting to Home, and turn off Viera Link demo.

Go into the menu, choose set up and re set to shipping settings.

You need to connect the tv on the network, press the green button on the remote, follow the instructions and the code will appear on the screen. But only few models of selected countries of these tv's have the Media Center Extender capability - if the tv that you bought doesn't have the Green button then you can't pair it up with your pc. In that case you will have to connect it to a router and configure it just like another pc - not directly to your pc.

You need to run a DLNA server on your Windows 7 PC, I recomend using a program called Serviio: http://www.serviio.org/
Simply download and install, select the folders that you want view on your TV and you should be viewing your films and pictures in no time.

This is controlled by the Split and Swap buttons on the remote; the size of the second picture can be adjusted with the Aspect button. First press split and use the Input button to select the source of the right picture of the split screen (TV channel or video inputs). Then press Swap and use the input button to select the source of the second screen. Swap again if desired or press Aspect to change the size of the main screen window. However, it is not available if you are using the HDMI, PC and SD Card viewing mode. Since the TV doesn't have dual digital tuners, you can't watch two different digital channels on the split screen.

The manual for the Panasonic TH-42PX600U is available from from Panasonic here: http://www2.panasonic.com/consumer-electronics/support/Televisions/Plasma-HDTVs/model.TH-42PX600U . See page 18 of the manual, page 10 of the PDF.

I hope this helps.
