clony Posted May 3, 2017 Share Posted May 3, 2017 Ma poate ajtua cineva cu identificarea acestei componente UB101? Tv nu porneste, nu se aprinde led-ul de standby si am 4 ohm rezistenta pe optocuplor in primar. Optocuplorul dat jos e ok. Are cineva o schema pt tp.s506.pb818 ? Link to comment

sorintv Posted May 3, 2017 Share Posted May 3, 2017 (edited) Ceva cu UB101 in sursa. https://haier.encompass.com/shop/model_research_docs/?file=/HAI/sm/32D3005B.pdf Posibil un OB2263 sau OB2273 ca in sursele LED Blaupunkt chinezesti. Edited May 3, 2017 by sorintvr Link to comment
cristronic Posted May 4, 2017 Share Posted May 4, 2017 Eu cred ca se poate monta SG6859ATZ si care se gaseste la pret destul de bun. Link to comment
SASSU Posted May 4, 2017 Share Posted May 4, 2017 Pai trebuie vazut schema interna la ambele Link to comment
Florinel TV Posted May 4, 2017 Share Posted May 4, 2017 Dupa cum vad eu in poza 3 pini sunt pe gnd si pe el scrie 30R sa nu fie 3 rezistente incapsulate intro capsula Link to comment
clony Posted May 4, 2017 Author Share Posted May 4, 2017 Dupa cum vad eu in poza 3 pini sunt pe gnd si pe el scrie 30R sa nu fie 3 rezistente incapsulate intro capsula Doar pin 1 este legat la GND printr-un condensator. Am dat azi comanda de 1 OB2263 si vad cand ajunge cum se comporta Nu are nimeni o astfel de placa defecta, cu probleme de soft sau sa aiba tensiunile pe secundar? As cumpara si una partial defecta daca nu gasesc acest integrat. Link to comment
