Samsung ue48h5003aw

Recommended Posts

Buna ziua !

am un televizor samsung ue48h5003aw care porneste apare backlight  fara imagine sau OSD sunet are .

Daca decuplez panglicele de la ticon la panel apare jumatate de imagine.

ticonul panelului are foarte putine piese cateva diode si condensatori

Cu panglica din stanga pusa, toate tensiunile cad,am masurat la rece ,ohmetric,nu pare a fi rezistente fata de masa

Ma bate gandul sa pun sursa cu 12V si 5A sa vad daca se incalzesc condesatori ceva

Cel mai probabil un consum mare pe tensiunea VGH. Daca ai noroc gasesti un condensator smd cu rezistenta. Sau o dioda. Eu alimentez separat VGH din sursa externa si cresc usor tensiunea pana la valoarea data de producator. Ce este defect se incinge sau face....poc. Cauta o dioda in stanga sus.
