OVP Orava CTV2184A - trasnit

Recommended Posts

Salut! Am de reparat un TV OVP CTV2184A care a incetat sa functioneze in urama unui trasnet. Problema este ca nu identific sasiul sau vreo schema care sa semene cat de cat. Are cineva vreo schema care sa coincida cate de cat cu sasiul asta? Multumesc anticipat!

Salut! Am reusit sa pornesc sursa, avea ars UC3843, MOSFET-ul si o dioda redresoare de pe B+. Acum problema este ca nu am mai avut sa-i pun dioda BYT52M si i-am pus prima oara 1N5408 (a mers vreo 5 minute si a ars-o) dupa care am pus 1N5062 (s-a ars dupa 3 minute desi era de 2A si nu de 1,4A cum era originala). Tensiunile sunt in regula cat timp functioneaza. Am sa incerc sa-i pun becul ca sarcina sa vad daca imi mai arde redresoarea. Ce dioda mai merge pusa in loc de BYT52M (1000V, 1.4A). Schema se bazeaza pe TDA9351PS/N3/2/1754 Multumesc!
