#1 Panasonic TX-48CX400B - podświetlenie gaśnie.

Witam,
posiadam tv Panasonic model TX-48CX400B.
Objawy:
tv prawidłowo się uruchamia, obraz jest, dźwięk także.
Podświetlenie tv przez kilkanaście sekund od uruchomienia, później gaśnie.
Jakieś wskazówki ?
Na moje gdyby któraś dioda LED była uszkodzona to nie byłoby wogóle podświetlenia o ile rozumiem ?


obsada TV:
Zasilacz VESTEL 17IPS20
T-con to 14Y_J1FU13TMGC4LV0.0

Proszę sprawdzić diody.
Taki objaw może występować przy uszkodzeniu jednej z nich.

Jeżeli dźwięk zostaje i działa pilot to 99% któraś z diod.
Ile przewodów zasila panel?
