Sziasztok TanyaTagok!
Ezeknél a lapoknál egy fehér kerámia? cucc van a proci tetején.
Ez rá van ragasztva?
Hogyan lehet gyógyítani? Mármint mivel lehet hozzáférni / kellően melegíteni? Csak BGA rework géppel? (Sokszor eredményre vezet egy precízen kivitelezett melengetés forrólevegős állomással.
Válaszaitokat köszönöm:
Péter

Üdvözletem mindenkinek !
Már megint belefutottam egy komoly hibába.
Szeretném megkérdezni a nálam tapasztaltabb kollégákat , hogy mire tippelnek a következő hibajelenséggel kapcsolatban .Én személy szerint a kijelzőt gyanúsítom.
A tv bekapcsolását követöen kijelző felső 1/3 felében látható a kép az alsó 2/3 rész függőlegesen fehér és szürke csíkok láthatóak.
Majd 20 perc bemelegedés után teljes lesz a kép(de nem hibátlan).Akkor is marad egy vízszintes csík és átnyalatni színkülönbség. A fényképen jól látható.
Ennek a kijelzőnek mindkettő oldalán van cof fülek. Valószínű,hogy átköthető.
A kijelző típusa: LC320WUD
