Salut am si eu un tv thomas tcb-063tx care porneste din telecomanda dar nu afiseaza nimic si nu are nici sunet. Am schimbat toti condensatori din sursa cu alti noi dar degeaba.Am masurat tensiunea in secundar am 116v am masurat pe cadre am si acolo tensiune am si inalta dar tot nu vrea.Am marit ug2 si pe ecran apar niste dungi subtiri paralele de la stanga la dreapta si nu stiu ce sa-i mai fac.va rog frumos daca se poate sa ma ajutati cu ideile dumneavoastra. va multumesc frumos.

Uita-teb pe modulul de teletext..anumite "placi"......au avut un condensator de 22uF,romanesc de IPRS,cu carcasa de platic gri...si dadea defecte urate si ciudate......si vezi sa iti functineze corect stabilizatorul de 5 volti....lipituri proaste la stabilizator,condensatorul de 10 uF.....
