Defect ascuns TV AIWA 215AT.

Recommended Posts

Televizorul AIWA 215AT, are imaginea buna ca-si culoare, contrast si luminozitate, dar este brazdata de niste unde orizontale in "S" care curg de la dreapta la stanga.Am verificat daca acest lucru se intampla si cu samnal de la un DVD player extern; DA deci probleme nu este de la transmisia prin cablu locala. Asa ca am inlocuit condensatorul de filtraj pe alimentare si 2 condensatori de filtraj de langa chopper si nu s-a rezolvat nimic.Nu stiu daca ceea ce se intampla este un efect de moire ?Nu stiu cum se manifesta acesta ?Va rog dati-mi sfaturi in aceasta problema !
