Caut integrat

Recommended Posts

Am umezit degetul si l-am plimbat pe picioare la LA78040 iar rastrul tinde sa se desfaca....Asta nu inseamna ca etajul de verticala lucreaza?Eu asa stiu.....Tensiunile de de alimentare a LA78040 este +29V.Nu este comandat...Pe deflexie am +22V.Am facut varianta din Depanatorul pt recuperarea M52309 ramane dunga insa este serpuita nu dreapta....Parerea mea este ca 90% este TMPA 8823 defect.Memoria am schimbat-o insa fara nici un rezultat,am schimabat de asemenea si condensatorul de pe Vsaw.Rog o oferta pt integrat daca are cineva s-au alte sugestii...Multumesc.
