I assume this is happening when watching a range of media eg Netflix\Amazon, terrestrial, and Bluerays\Sky boxes?
Or does it only happen on one particular source?
No your not charged for follow on questions, sorry I didnt see your response.
If its happening across a range of sources it sounds like this is a video processing fault.
You can try and use the different picture settings, however if its that obvious I would look to take the unit into a service centre and get them to check if the TV news a new control board.
What is the model number of the TV, and I will see what picture settings and modes are available.
I have noticed something similar on my Samsung 8000 but its only when you get jet black, it looks patchy in places, but Samsung have said thats just down to the video processor. Give me a few minutes and I will see what your options are for changing settings yourself.
To edit the picture settings, press the menu button.
Select Picture and then viewing mode from the sub menu.
There should be 9 or 10 different modes you can play with to see if the issue is less obvious.
If you dont have the TV manual to hand, you can have a look at the manual here, which lists the options and what they are normally for and how to set a professional or custom mode.
As I say its not just Panasonic, however confident if its happening across all sources its a TV fault rather than poor HDMI cable etc.
The only other thing you may want to check is the TV is up to date as it may be a software fault they have fixed with the latest release.
Agreed, I have also check the engineer notes for your TV there is no recall or anything listed by Panasonic as a known fault
You can certainly call them, they will ask you to take it into a service centre, they will put a test card on and most likely shrug it off, but certainly worth getting them to look at it.
You can find the nearest service centre here.
Its not a great job, but when you see some of the delivery men that take them you probably would prefer to drop it off yourself.
No problem, appreciate if you can rate the service received this evening.
