 Dungi verticale colorate,lipsa imagine!! Nu stiu daca tv-ul a ramas pe functia de TV sau pe vreo intrare auxiliara,gen HDMI,SCART...deoarece cu cablul de antena bagat NU are sunet ! Porneste ,opreste din butonul de pe panoul tv! Suspectez placa t-con : T550HVN08.2 CTRL BD 55T23-C03 cu eticheta aditionala : TT-5550 T20C20-649-M255279-04288-02! Am cumparat o alta placa t-con,tot din seria T5550HVN08.2 CTRL BD 55T23-C03 dar cu eticheta aditionala seria : TT-5550 T20C12-618-JJZ18453-19. Cu noul t-con ,la pornire ,ledul de st-by trece din verde in alb succesiv.....fara sa porneasca tv-ul....nici iluminare panel!! Cu t-con suspectat defect ,tv porneste cu ,dungi,inclusiv iluminare panel! Am inteles ca noul t-con ar trebui ''imperecheat'' cu placa de baza si panelul meu !! Adica rescris softul in una din cele doua memorii de pe t-con : U401( 24C32R ) sau cealalta FLASH (25Q32) nu stiu exact care!! T-con-ul are o mufa dedicata pt aceasta operatiuneAre cineva idee....a facut cineva aceasta operatiune si mai ales un soft adecvat tipului de panel si placi de baza scrise mai sus

Am pus cele doua memorii de pe t-con cu dungi ,pe noul t-con,efectul fiind ca tv-ul da eroare 5 flashuri ,adica t-con sau panel defect !!

Panelul este V500FWME01 si nu cred a fi defect! Cu t-con-ul cu dungi,toate tensiunile (VGL,VGH ,ADD,etc ) sant ok!!

Verificati panglica dintre t- con si mb.

Este foarte sensibila si se intrerup traseele catre mb.

de asemenea trebuie resoftat tv- ul dupa inlocuire t- con.
