Recommended Posts

Am un prieten cu un tv Amstrad tv2714 la care s-a defectat partea de alimentare care are urmatorul cod "04ta069g". Am gasit condensatori umflati pe care i-am schimbat , am verificat ceilalti cond cu esr-metru si par buni ,optocuplorul ic20 l-am gasit explodat , dupa inlocuirea acestora la actionarea butonului pover se aprind pentru o fractiune de secunda tuburile neon iar ledul verde clipeste des iar la decuplare se aprind iarasi tuburilre pentru scurt timp la masurare tensiunea de 5v stand by este de fapt circa 8v, daca are cineva shema acestui tv as fi foarte recunoscator :jytuiyu
