Hello Alain,
You need to use two-step authentication to log in to Google, otherwise it just will not let you log in. Then, you will need to update the software – then (in my experience) reset the TV to default and log in again. After that, leave the TV for a day or two to ‘stabilise’
The BV14 is a lovely TV, but… as with all B&O products of the era, it’s all about software.
