daniel_ac Posted June 24, 2014 Share Posted June 24, 2014 (edited) Am primit un tv grundig cuc 2130 cu STV9306 A/B(cred) lipsa. Nu stiu care din aceste 3 modele le-a avut. Conform pdf-ului am gasit STV9306 si/sau STV9306A momentan nu ma prind care este diferenta dintre ele. Incerc sa evaluez pagubele sa vad daca se justifica investitia/reparatia. Traful de linii "scapa" FIT = defect, modelul hr8665 Care este tensiunea corecta de alimentare in punctul A (U final linii), nu am gasit nicaieri specificat in pdf. Sursa pare sa functioneze corect, celelalte tensiuni existand si conform schemei sunt ok, mai putin U final linii l-am gasit 180V??? nu sunt convins ca este corecta. Putin ajutor va rog. multumesc Edited June 24, 2014 by daniel_ac Quote Link to comment Share on other sites More sharing options...
Toni Marginean Posted June 24, 2014 Share Posted June 24, 2014 CI vertical este STV9306 simplu iar tensiunea de alimentare +A este functie de tub intre 135 si 152V. Fiind tensiunea de alimentare mare trafo linii descarca. Quote Link to comment Share on other sites More sharing options...
daniel_ac Posted June 24, 2014 Author Share Posted June 24, 2014 Mare dreptate aveti cu tensiunea, daca ma uitam mai atent la pagina cu transformatorul de linii si STV in tabel sunt specificate tensiunile in raport cu tipul si diagonala tubului. multumesc pentru indrumari Quote Link to comment Share on other sites More sharing options...
daniel_ac Posted June 25, 2014 Author Share Posted June 25, 2014 sursa cu bec montat are tensiune de 145V, daca inseriez becul cu traful de linii creste la 180-190 Quote Link to comment Share on other sites More sharing options...
