Philips TV 55pus6162/12 screen upside down

[Carmelo Labadie]

Hi all,

Since a week ago, the picture of my Philips tv 55pus6162/12 is inverted, upside down, on all sources, all menus, even on the philips logo when powering on.

I tried performing a factory reset, a firmware upgrade through usb,.. Nothing changed this situation.

The service menu (062596) has no (self explaining) invert option.

Any idea?
