led finlux 26'' cu probleme display


Recommended Posts

imaginea pe display este statica si plina de liniute fine orizontale, dupa ceva timp, zeci de sec., ecranul se albeste iar cind schimb programul din telec. reapare o imagine ca la inceput si se continua secventa, defectul poate fi din ecran sau PCB-ul alipit :  ecranul este BOE / HT260wxc-200 iar PCB-ul contine driver-ul de led-uri ( rt8566 si n6066ss ) si lvds-ul cu circuitele aferente display ( HX8861-F timing kontroler , 042z reglaj Vcom, RT9955 gen. tensiuni multiple vgh, vgl,...), dvs. ce parere aveti ?

citeva sfaturi ?

tensiunile par bune,  Vgh =24v, Vgl= -4,5v,

Cat ai stat sa astepti pana acum faceai 1000 de poze, da deee, ce sa zicem toate lcd-urile sunt echipate cu acest display si acelasi defect, ce rost mai are sa desfacem ecranul si sa facem cateva poze ici si colo..daca defectul e comun....nu mai trebuie alte detalii....vrem sa luam de-a gata fara sa muncim...asa ceva nu prea se poate!
