tv LG 26LC3R

Recommended Posts

Buna ziua, am un TV LG 26LC3R caruia i se intrerupe back light-ul in momentul in care conectez semnal pe una din cele doua intrari AV. Tin sa mentionez ca pe tv analog functioneaza perfect .Toate tensiunile sunt OK!Multumesc anticipat tuturor ce m-ar putea ajuta cu un sfat

Multumesc mult pentru raspuns, am verificat intrarile sunt OK nu au vreun scurt, am uitat sa mentionez ca dispare backlight-ul dupa 2-3 secunde de la conectare

dispare comande ON de pe inverter.

Doar cand il cuplati pe AV??? Ciudat!!! Si pe tuner merge ok,nu se intampla nimic?!?! De la ce-i dati semnal AV?!?Dar daca il treceti in AV din telecomanda fara sa-l cuplati la o sursa AV si atunci dispare lumina?!?!
