MY MUMS TV ONLY 4YEARS OLD 42"PLASMA HAS CHANGED LANGUAGE AND DOESNT GIVE YOU A CHOICE OF ENGLISH, ALSO NO PICTURE ONLY HAS SOUND AND WHEN TURNED OFF AND BACK ON HAS A COUNTDOWN 4MINS - 0 THEN TURNS ITSELF OFF
PROBOBLY UNREPAIRABLE BUT YOU NEVER KNOW SOMEONE COULD SOLVE THE PROBLEM !
Do you have an instruction manual for the TV? Have you tried unplugging it (as opposed to just turning it off)? If nothing works, it would be worth it to pay a TV engineer to come and repair it.
Do you know what language you changed it to? I have a mobile phone when you change the language it also changes the names. For example if you change the phone to Italian in the language screen it says Inglese not English.
