LG 32LS3400 nem indul
Sziasztok! Adott a témában szereplő tv. Előélete nem ismert. A tápban szakadt volt a bizti, valamint zárlatos volt a táp fet. A fet és bizti csere után világít a stand by, meg is van a 3,5V, de bekapcsolás után 3-at villog a stand by led, majd nem világít, kikapcsolás után átvált folyamatos pirosra. Tehát ki-be kapcsolásra reagál, mintha működne rendesen, de a tápon nincs meg a 12v és a 24V, csak a stand by. Mi lehet még a gond? 
i have a strange problem with my LG 55 led tv HDMI INPUTS.

when i connect the cable tv HDMI to the HDMI input of the lg led tv .the tv says NO SIGNAL .but if i connect to the same inputs a china tv box all is working fine. all the HDMI inputs are the same. non of them work with cable tv but work well with the china tv box.
