Sziasztok!
EEPROM-ot cseréltem, ugyanaz a jelenség, EEPROM nélkül semmit sem csinál.
Feszültség alá helyezéskor folyamatosan világít az előlap, mert be van kötve az ILL bemenete is, bekapcsolás után villogni kezd szabályosan, és nem reagál semmire.
Van valami ötletetek rá?
Üdv: Jácint
Segítségeteket kérem! Sehol sem tudom beszerezni a µPC 555-es IC-t, amely egy Sansui tuner javításához kellene. Ha valakinek van ötlete, ossza meg velem!

Sziasztok!
Keresem Clatronic SLS 570 kapcsolási rajzát ,ha valaki tud segítsen
előre is kőszőnöm.
A fenti autórádió.cd-vel elakadtam. A készülék működik, csak a hangszórók némák.
A vonalkimeneten is jó, a végfok kap tápot ,jelet,stby-t. cseréltem a ta8275hq-t, a kimeneti lábakon 7,5 V mérhető bekapcsolt állapotban, a rajta lévő diódákon 3477 felirat van, jóknak tűnnek. Kicsit melegszik, bár a hűtőbordát még nem tettem rá. Valakinek volna ötlete, mit nézzek meg?
Előre is köszönöm.
