Reglez progr. -fine tuner ,il memorez = OK , dupa 2-3 min ,, fuge" usor in partea superioara , imag. cu desincroniuzare. Care C sa-l mai verific ? Cu stima , Virgil.

Nu este defect de CAF?.... Incercati sa refaceti reglajul bobinei din demodulatorul de FI. Eu vad ca este echipat cu TDA8362,deci este bobina dintre pinii 2 si 3 ai integratului. Eventual bobina schimbata.

100% este din CAF.Este tipic la cele cu TDA8362.Merge acolo orice bobina luata din alt TV cu 8362.
