defect: ecranul verzui cu dungulite orizontale;are sonor. La masuratori am constatat ca tensiunile pe tunurile rgb sunt egale cu tensiunea de alimentare a finalului video(tda6107q) adica 180v.La actionarea screen-uli se modifica aceste tensiuni cu iluminarea respectiv intunecarea ecranului.Am inlocuit tda6107q si tda8842 dar defectul persista :nas:o schema sau idei sunt binevenite multumesc tuturor
