TV LCD HANTAREX cu probleme

Recommended Posts

Buna ziua... Sunt in posesia unui tv lcd Hantarex 32sgtv cu o problema Defectul se manifesta in felul urmator..se aprinde ledul rosu de stand bye...la actionarea telecomenzii sau al butonului frontal de start, se aprinde si ledul verde pentru 8-10 secunde, apoi se restarteaza si in continuu la acelasi interval de timp.... Tensiunile sunt ok (24..12..5v de pe sursa)...am schimbat majoritatea condensatorilor... Neoanele au fost verificate si sunt ok... Poate fi dumpul?...ma poate ajuta vreun coleg cu un dump ptr acest tv?HANTAREX LCD 32SGTVplaca video--- CHAGALL2 REV 01..am gasit si ceva documentatie...va multumesc anticipat

"Tensiunile sunt ok (24..12..5v de pe sursa)" - raman stabile in cele 8 - 10 sec. ?

si 24v este stabila.....ptr a verifica neoanele, am alimentat separat pinul ON/OFF cu o sursa externa de 3.3v,deoarece nu este tensiune pe acest pin...

Nu poate nimeni sa ma lamureasca daca este nomal sa am un consum asa de mare pe ramura 3.3v?Am observat ca doar Micronas VCT 49X3 se incalzaste relativ putin si ld1117-33 destul de mult...
