(Kirjoitin seuraavan puhtaaksi ystävälliseltä paikalliselta RTV-huoltajalta saamastani valokopiosta. Valikkokuvissa varmaan kuuluisi olla värejä, mutta ne ei näy valokopiossa. Jos käyt huoltovalikossa, kannattaa olla tarkkana ettei muuta vääriä asetuksia tai muuten pahimmillaan kuva ja kaikki muu saatta mennä aivan vikuralleen. Oman TV:n arvot kannattaa kirjata ensiksi paperille muistiin)
CONFIGURATION AND FAULT DIAGNOSIS FOR CIRCUITS CONNECTED TO THE IIC-BUS
