Panel lLTJ400HM04-B

Recommended Posts

Buna seara, am si eu a cest tv samsung care se manifesta dupa cum se vede in pozele de mai jos.

Am deconectat pe rand cate o panglica de la t-con la panel dar defectul persista pe ambele parti. O metoda de depanare a acestui panel, eventuale filmulete ar fi foarte bine venite. Multumnesc!

100% panel defect, incercati sa presati usor panglicile, poate aveti vreo sansa de reusita.

Mi-am dat seama ca defectul e exclusiv din panel, o sa-l verific maine mai amanuntit dar se pare ca a mai fost umblat la acest panel.

28.9v respectiv -7.4v Normale zic eu.

Am palpat panglicile dar fara nici o modificare. Am observat altceva, daca deconectez panglica din dreapta se vede negru pe acea jumatate, dar cand deconectez si partea din stanga  ramane imaginea pe partea stanga si se pierde treptat(avand ambele panglici deconectate) Asta mi se pare ciudat...

E clar ca panelul e defect dar ce anume? Traseele in panel, circuitele de pe panglici. Care e explicatia ca pe o parte cu panglica deconectata imaginea ramane pt cateva secunde si dispare treptat? Am intalnit multe paneluri defecte dar nici 1 cu acest defect...
