multumesc , deocamdata l-am curatat putin de praf si l-am lasat sa se acomodeze la temp. proprietarul mi-a spus ca s-a "jucat" la telecomanda. o sa-i verific si bobina de deflexie si circuitul de corectie E-W. daca defectul este cunoscut la acest sasiu , nu mi-ar prinde rau niste sugestii.

:aplauze Buna seara. Defect rezolvat! ... dupa ceva sapaturi am gasit un cond. C407 ( 270pF/250v ) in scurt, dar acest cond.nu l-am gasit decat pe sasiu...in schema nu este. In schimb in schema , pe circuitul de corectie E-W am gasit C411 notat de 3 ori , cu trei valori diferite.... C413 de 2 ori si multe alte notatii gresite. Multumesc !
