sebybastian Posted January 5, 2011 Share Posted January 5, 2011 Buna ziua.Am o problema la un samsung sasiu SCT-11B: la pornire am imagine doar pe 3/4 din ecran iar dupa 10 minute de functionare imaginea revine la normal.Am verificat tensiunile conform schemei si sunt ok. Condensatorii de pe tensiunea de 24V si de pe langa circuitul respectiv (TA 8445) care erau devalorizati i-am inlocuit.Nu am osciloscop sa pot verifica cu precizie formele de unda.Ce as mai putea verifica? Va rog un sfat. Multumesc. Link to comment Share on other sites More sharing options...
