Hi @ZSOLT88 Felhívjuk figyelmét, hogy ez a közösség nyelve az angol.
Translation: home button doesn't work, what could be wrong?
Would you please start by letting us know the full model number of your TV.
This has happened to me in the past, a quick telephone call to Sony Support told me to key in a sequence that bought back the Home key.
I would try a soft reset first, hold down the remote power button for several seconds until you see Restart.
