SHARP LC-60LE635E, csak kettőt villog a led! Main board hibás!


A fent nevezett készülék áram alá helyezve megjön a készenlét. Bekapcsolva kettőt villog a led rajta, de semmi más életjelet nem ad. Ezt addig csinálja amíg a power gombbal ki nem kapcsolom. Ez most valami hibakód lenne? Vagy esetleg szotver hiba? Honnan lehet letölteni a szotvert, és hogyan kell beletölteni? A segítségeteket előre is köszönöm.
