Thanks for waiting.
Here is how to change the language;
Open the tv`s menu and go to the 4th icon down , that is the one that looks like a gear (setup) , open this and go to the second selection /item dowm and use the side arrow to open it and select english .
You should then have everything back to normal .
By the way , you can download your manual at the link below ;
Its on page 26 of the english only manual
