raresv Posted June 14, 2022 Share Posted June 14, 2022 (edited) Buna seara, este vb de un TV LG43UJ620V, apare uneori pt foarte scurt timp LG pe ecran si apoi se stinge. De cele mai multe ori clipeste ledul rosu. Am masurat si sunt prezente tensiunile de 13.2V, cum as putea verifica daca este vb de led-urile de back light sau de sursa? Am vazut ca exista 2 ramuri de alimentare a LED-urilor dar in lipsa unui doc tehnic nu stiu ce tensiune/curent sa livrez. https://postimg.cc/BtG7Fzpr Edited June 14, 2022 by raresv Quote Link to comment Share on other sites More sharing options...
