The problem just started last week but I was away on holliday so have only just had to deal wqith the problem
It is a Panasonic TX-42A00B flat screen but not smart TV. It works fine as a monitor with virgin cable, or as a monitor for recording, or as a picture viewer with a USB. But on Freeview on primary input it will not keep the ( 164) chanels after tune up

I guess the TV model number would be TX-42A400B or some thing?

Since TV loses channel data that indicates EEPROM (memory) chip failure, this chip would be mounted on main board of TV and entire main board will be replaced to resolve the problem. I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. If TV is out of warranty then you would need to take the TV in repair shop for main board replacement and this kind or repair may cost around 90 plus Pounds or so. I trust my input will help you out. Please feel free to respond if you have any additional questions.
