Va salut.

Acest tv are probleme cu alimentarea ledurilor de backlight in st/by,ceea ce nu am intalnit pana acum.

La pornire tv totul ok,dar cand il trec in st/by ledurile raman aprinse slab cu o tensiune pe led de 2.5v.

Driver-ul leduri este MAP3202,sursa alimentare cu comanda leduri pe ea este EAX64905001,initial tv-ul a avut toate ledurile in scurt,am schimbat ledurile cu cod 32 conform tabel de la D-ul Badila V....e,cod bareta POLA 2.0 32''.

Tensiunile masurate pe leduri in on are 66v rezulta 3.5v/led,in st/by am 47v rezulta 2.5v/led. Tv este echipat cu 2 barete a cate 6 leduri si una cu 7 leduri.

Am mai luat leduri de la d-ul Badila si nu am avut probleme cu ele.

A mai intalnit cineva fenomenul acesta si cum a rezolvat?

Va multumesc pentru timpul acordat.
