Buna ziua , acest lcd are imagine 2 secunde dupa care se stinge iluminarea panelului si se aude doar sunetul . Am verificat bara de 24 volti era ok dar am schimbat totusi electroliticii dar fara rezultat . Modulele invertoare master slave sint ITW-EE26-M si ITW-EE26-S iar controlerul cu care este prevazut masterul est OZ9936 , exista vreo modalitate de eliminare a protectiei ? Multumesc .

Am revenit la acest lcd , cautind pe net am gasit o rezolvare care merge la acest tv , in pinul 1 trebuie injectat 2 volti dar cu pinul deconectat de la restul circuitelor , ridicat in aer de pe pcb si asa alimentat cu 2 volti . Eu am gasit un 5 volti pe un condensator smd din zona pinilor 7 - 8 , am lipit un semireglabil de 22kohmi intre masa si acei 5 volti , am reglat sa fie 2 volti pe cursor si apoi am conectat la pinul 1 OZ . Dupa pornire nu s-au mai stins neoanele cu toate ca masurat pe pinul 1 era 1,90 volti .
