SONY BRAVIA KD49XD8305 PLAY STORE says: Something went wrong, check your WIFI

[elioloconte]

Good morning,
I have a SONY BRAVIA KD49XD8305 TV with Android.
Since a few days PLAY STORE does not work anymore... it tells me it can't find WIFI, I need it in order to update an app.

I've tried everything, deleted the cache, updated software (PKGS.7220.0365EUA), reset, change WIFI, use ethernet connection..... , when I check the connection, it says that EVERYTHING IS OK and indeed other apps (NETFLIX, RAIPLAY, YOUTUBE etc) work normally, only PLAY STORE doesn't.

What can I do ?

Thank you
