BUGHIU Posted July 11, 2012 Share Posted July 11, 2012 Cum adica,credeti ca cele doua tensiuni nu sant in regula? Ce face/nu face aparatul?!?! Link to comment
florinellll Posted July 11, 2012 Author Share Posted July 11, 2012 Scuze de intarzierepe c.i. scrie K052 1117 33 .Se pare ca ar fi echivalent cu LM1117-33.Tv-ul functioneaza aparent normal insa la un moment dat dispare imaginea sunet normal,convertoarele functioneaza.Ar mai fi o problema c.i..SI9933BDY se incinge foarte tare din prima secunda de functionare ,dar tv functioneaza normal.Daca deconectez modulul LVDS ,regulatorul ..SI9933BDY nu se mai incinge.Voi cumpara un SI9933BDY care este echivalent cu FDS4953 sa vad ce se intampla.Daca aveti sugestii sunt bine venite.

BUGHIU Posted July 11, 2012 Share Posted July 11, 2012 Ozn-ul(integratul) ala mare de pe placa lvds nu ''fierbe''in timp relativ scurt??Dar daca deconectati panglicile de la panel? ce se intampla cu ....temperatura lor?!?! Practic lasati placa t-con fara ...sarcina daca decuplati panelul. Link to comment
dan cod Posted July 12, 2012 Share Posted July 12, 2012 Scuze de intarzierepe c.i. scrie K052 1117 33 . Se pare ca ar fi echivalent cu LM1117-33. Este echivalent si este un stabilizator de 3,3V.Deci pe intrarea lui ar trebui sa aiba vreo 5V si pe iesire 3,3V.Deci clar ceva nu-i in regula acolo.Ori ceva consuma mult ori nu primeste cat trebuie pe intrare.

florinellll Posted July 12, 2012 Author Share Posted July 12, 2012 Rezolvat.C.I. defect SI9933BDY se ambala termic ,furniza doar 2,9v ,corect 5v.L-am inlocuit cu ce am gasit respectiv IRF 7316. Link to comment
