uP SDA20563-A516 Beko

Recommended Posts

O problema destul de ciudata la un TV Beko, in sensul ca nu mai regleaza lumina, culoare, contrast ( tens. rez. in urma integrarii la iesirea uP SDA20563-A516 nu se modifica, desi pe OSD apare ca s-ar modifica )Cu alte cuvinte, iesirile SDA20563-A516 pt. comada analogica a TDA8362 nu trimit comenzi catre jungla. Jungla e OK ( defect uP sau prb. de soft ).Prin intrare in menu service apare o rubrica cu TDA4680. Acest IC se comanda cu magistrala I2C si n-are nici o treaba cu TV in cauza ( acelasi TDA4680 e folosit cu uP SDA20563-A516 intr-un model de TV NEI ).Stie cineva cum se poate modifica din menu service uP a. i. sa se poata activa iesirile uP ( pinii 18, 19, 22 ) pentru comanda TDA8362?Sau trebuie musai inlocuit uP?
