Buna seara!

Stie cineva pe unde pot gasi lampi in forma de U pentru un tv lcd de 46" Samsung le46b530p7w, am cautat online si nu am gasiti nimic in RO, sau daca se pot adapta barete led de la un Samsung led tot de 46". Baretele le-am gasit de cumparat insa ce fac cu driverul necesar pentru ele?

Va multumesc, stima!

 

L.E. : Uitasem sa spun ca are momente cand ecranul sta si 2 ore deschis fara sa schiteze nimic, alteori se deschide pentru cateva secunde apoi se inchide ramanand doar sunet.

Revin cu problema acestui tv!

In momentul in care tv-ul sta deschis ceva vreme si apuca sa se incalzeasca, daca il inchid si apoi il deschid, backlight-ul dispare in cateva secunde. Daca insist, dupa vreo 2-3 reporniri, isi revine, sta aprins.

Ciudat faptul ca in momentul in care deconectez cablul de la mainboard, backlight-ul sta aprins, indiferent ca e rece sau cald tv-ul.

Am verificat tensiuni, ok!

Tensiunea inv-on, in momentul in care backlight-ul pica, ramane de 5v.

O alta problema ce ar fi la acest tv, nu pastreaza setarile dupa ce il repornesc.

 

Mainboard: BN41-01165A

Psu: BN44-00265B

Invertor: CMO T87i030.0

Panel: ChiMei V460H1-L06 rev.C1

Acum 18 ore, Costica Tv a spus:

Daca backlightul sta aprins continu cu mufa dintre sursa si main deconectata, defectul e pe main, torsioneaza usor placa cu tv-ul pornit si vezi ce face.

Va multumesc! Asta banuiam si eu! Revin cu informatii dupa ce fac cateva masuratori pe mainboard, eventual il si "gatui putin" :D
