Buna ziua , acest televizor crt sasiu MD1.1E AB functioneaza corect in afara de oprirea in st-by . La apasarea butonului respectiv de pe telecomanda ledul se face galben , dispare sunetul dar ramane imaginea cu programul pe care se afla . Daca in faza asta este oprit din butonul ON-OFF ledul pana sa se stinga trece in rosu pentru o secunda , repornit din buton ledul lumineaza galben , nu este inalta ( este ca si cum ar fi in st-by ) , pornit din telecomanda sau buton P+ panou , ledul se face verde si porneste corect cu imagine si sunet . Pana in acest moment am schimbat dump memorie 24W04 pentru procesor TMP87CM36N-3425 si optocuplorul CNX82A . Multumesc pentru informatii suplimentare .

Verificati/schimbati R3588,valoare critica(3,3ohm toleranta 5%) ; eventual verificati/schimbati si C2561 cu un capacitor de 3300uf/16v.....poate se rezolva!!!
