Buna ziua.Am probleme cu un tv echipat cu aceasta placa....am pus leduri noi se aprind 3 secunde apoi se micsoreaza la minim lumina apoi iar revine la normal si tot asa continuu....nu ramine fluxul luminos la normal...cind se aprind normal tensiunea e de 153v iar cind scade ajunge la 109v..masuratorile au fost facute cu ledurile conectate.aveti ceva idei...multumesc,,,

Are ceva probleme pe controler , asa cred eu, in caz ca baretele sunt testate cu tester-ul, daca baretele sunt ok atunci poate fi controlerul defect, eu am luat teapa de la ASWO cu STK-uri 2 buc, unul a fost ok si unul defect era pentru o combina Sony , pretul a fost piperat 720lei pe ele, acum poate fi si baretele cu probleme
