bobo Posted July 1, 2014 Share Posted July 1, 2014 buna seara. care este modalitatea de anulare a protectiei? am incercat sa-l "pacalesc" cu un led din pinul 4 la masa dar nu functioneaza. exista alta modalitate sau am omis ceva? multumesc anticipat.

Guest cata82 Posted July 2, 2014 Share Posted July 2, 2014 Mai inseriati cu ledul un rezistor de 5.1k alimentat la o tensiune de 8-15v. Quote Link to comment Share on other sites More sharing options...

Guest Posted April 14, 2016 Share Posted April 14, 2016 (edited) Salut. Stie cineva cum se anuleaza protectia la acest invertor: VIT71037.50 LOGAH REV.1, metoda cu led la pinul 4 sau 10(OZ964SN) am incercat-o, dar fara rezultat, gasisem odata pe un forum ceva asemanator, unde anularea se facea prin deconectarea unor pinii la LM339, dar nu mai dau de acel forum. Samsung LE37A557P2F CI-urile de pe Invertor: U1=LM339 U2=OZ964SN U3=LM324 Edited April 14, 2016 by Guest Quote Link to comment Share on other sites More sharing options...

leoncris Posted April 14, 2016 Share Posted April 14, 2016 (edited) Ai 5V in pinul 5 ? http://archive.espec.ws/section328/file19858.html Edited April 14, 2016 by leoncris Quote Link to comment Share on other sites More sharing options...
Guest Posted April 14, 2016 Share Posted April 14, 2016 Ai 5V in pinul 5 ? C8 , inlocuit ? Tv-ul functioneaza perfect 3-4 ore dupa care invertorul intra inexplicabil in protectie, ramine doar sunet-ul, mentionez ca am verificat lampii, chopper-e, c-urile de pe invertor, sursa e ok......., si culmea e ca doar cu capacul(tv) pus face aceasta manifestare, fara capac nu se mai opreste. Dupa intrarea in protectie a invertor-ului ramine 5v la pin-ul 5(OZ964SN). Quote Link to comment Share on other sites More sharing options...
Guest Posted April 14, 2016 Share Posted April 14, 2016 A testat cineva schema de mai jos, pe invertoare, care in afara de OZ964 mai are si alte integrate?(LM339, LM324........etc). Zice ceva rusu-l aici "В LCD LG 32LK330-ZB Инвертор VIT71884.00 REV:2.LOGAH (OZ964 + LM339) победить не удалось, то работает, то нет, но удалось отключить защиту только одновременно по 4 и 10 ногам. По отдельности защита не блокировалась", dar din traducerea google nu poti pricepe nimic. Quote Link to comment Share on other sites More sharing options...
