lg 60pk250 plazma tv tápjavítás után nincs kép
Üdv az Uraknak! A fenti tv táphibával került hozzám. Nem volt standby. A tápjában cseréltem 3BR1565JF regulátor ic-t és 1db shottky diódát. Ezek után a táp indul, feszek megvannak.Kivétel az Y-sus panelon lévő -Vy és VSC feszeket nem mérem. Valami ötlet esetleg? Nem vagyok a plazmába otthon, de jó volna megjavítani. A panel 60R1-es, a tápegység EAY60968901 Előre is köszönöm a segítséget, és jó éjszakát mindenkinek. Üdv Zoli
Samsung UE43NU7092U TV nem indul, sw hiba?
Sziasztok!
A fenti gép 12V-os ágán 2 db 470uF/ 25V elkó púpos volt. A táp 7-11V között pulzált. Cseréje után stabilan beállt a 12,6V.
De! nem indul, nem tud bebootolni. Szakaszosan villogtatja a stby ledet. Szoftver hibára gondolok, alacsony/ ingadozó táp miatt sérülhetett a tartalom.
Találtam benne a BGA-s NANDon kívül egy 24C512 eepromot és egy 25Q80 FLASHt. A kijelzője CY-NN043HGNV6V.
Ezek tartalmát kicserélném hátha ...
Megköszönném ha valaki tudna küldeni tartalmat vagy forrást hozzá.
üdv, colore
