i first wrote to Fxtec 2020-02-15, got a first answer 4 days later, was asked 2020-02-24 if i preferred a new screen to install myself or a repair service with Fxtec, and was confirmed 2020-02-26 to receive a new screen in the coming weeks - which arrived indeed yesterday, after all this covid hassle. so i am perfectly happy with their service.
now i only need the video HOWTO to replace the Pro1 screen...
ADDON : issue of switching screens solved : see here
