Does the backlight appear for ~1 second, when you turn on the TV and then disappears, or it is dead all the time?

Witam.
Sprawdź bezpiecznik F4.
Zmierz rezystancje po stronie wtórnego uzwojenia transformatorów inwertera - powinny wynosić około 1.1 kΩ.
Podaj napięcia z układu U3.
W celach testowych możesz wyłączyć ochronę (protect) układu U3 (OZ964). W sieci są opisy wyłączenia protect dla tego układu, jednak robisz to na własną odpowiedzialność - uruchamianie TV z wyłączonymi zabezpieczeniami może doprowadzić do pogłębienia istniejących już uszkodzeń.
Pozdrawiam
