Taken to replace the 555. Small worries ...

Taken to replace the 555. Small compatibility issues with my new TV Philips 55PUS7909 / 12 is out. Hoping Logitech rule problem fairly quickly (despite contact by telephone with their service, and the person on the phone was friendly and seemed to know his job). I keep everything the same for the basic commands that allow me still access the main functions of the various devices.
On programming the remote control, this is always done in the same way, either online or following software: for those who already had a Logitech product, no worries. By cons, for the one who will do it for the first time, it will have a little grope and probably use their service remains responsive.
Delivery always on top at Amazon.
