palcu ion Posted July 11, 2009 Share Posted July 11, 2009 daca programatorul e bun atunci poate fi defect c 127=2.7nf stiroflex sau eventual semireglabilul de reglaj frecventa linii r125 Quote Link to comment Share on other sites More sharing options...
Bird Posted July 11, 2009 Author Share Posted July 11, 2009 Buna ! Am schimbat cam tot ce era de schimbat de la oscilator am schimbat si integratul si..il aduc aproape sincronizat din semireglabil dupa care pleaca in sens invers frecventa modificandu-se vertiginos . Eu am de gand ..fie ca-l fac fie ca nu , sa-l dau degeaba cuiva pe care-l intereseaza ...Amatori ?? Quote Link to comment Share on other sites More sharing options...
palcu ion Posted July 11, 2009 Share Posted July 11, 2009 atentie,C=2.7nf trebuie sa fie stiroflex Quote Link to comment Share on other sites More sharing options...
palcu ion Posted July 11, 2009 Share Posted July 11, 2009 poti decupla U VAR de la programator si pune un semireglabil (+12v,masa,Uvar selector)ca sa fii sigur ca ai inlaturat posibilitatea ca programatorul sa fie de vina Quote Link to comment Share on other sites More sharing options...
Bird Posted July 11, 2009 Author Share Posted July 11, 2009 Va salut ! Am gasit fisurat cablajul pe pin28 . dar nu e rezolvata problema . Acum il pun in stare relativa de sincronizare , apare un gen de "50Hz " pe marginile verticale si cand se desincronizeaza e si pe linii si pe cadre (asta mai rar ).Odata cu desincronizarea apare si un fel de tarait O FI O DESCARCARE ??.

dariuspopescu Posted July 16, 2009 Share Posted July 16, 2009 incearca sa ii schimbi driverul tz final linii (u501) .Daca nu ai unul de Sport monointegrat, incearca schimbarea cu unul de tv cu 5 CI. Quote Link to comment Share on other sites More sharing options...
