dan cod Posted October 30, 2012 Share Posted October 30, 2012 Eu asta as face primul lucru as rescrie dumpul.De ce nu poti?nu ai interfata?trebuie atunci ori sa iti faci una ori sa iti cumperi .Nu mai faci nimic acum in depanare fara sa poti programa macar memorii uzuale.

coman ion Posted October 30, 2012 Share Posted October 30, 2012 Acest sasiu porneste si cu memorie goala dar trebuie asteptat ceva mai mult decat de obicei dupa comanda on(eventual se dau mai multe comenzi).Nu cred ca aici e problema.Din ce spune autorul ,tv trece in stby in momentul in care ar trebui sa apara imaginea,adica dupa trecerea perioadei de blancare ,la aparitia curentilor catodici.Este defect tipic de tub slim.O proba pe alt tub ar fi edificatoare.

virgil_19 Posted October 31, 2012 Author Share Posted October 31, 2012 Va salut. Nu cred ca problema este din cauza tubului. . Am inlocuit mem. orig. cu 24WC64 , TVC porneste indicand ,, Hotel ..." in partea de jos a ecranului , imag. tremura . Tot din memorie este problema . Momentan nu am una goala sa verific. Ma intereseaza o schema o schema functionala , prt. rescrierea mem. Cu stima , Virgil. Link to comment Share on other sites More sharing options...
