Hello. I’m new on forum. I have blown amplifier digipro 1000 from DB technologies. I found some bad parts, but cannot identify this diode. It has marking 31. In wiring it is d12 and d13. Scheme is there: https://elektrotanya.com/cgi-bin/download2.cgi?uid=19628&cid=1541665480&fid=289613&file=db-technologies_s10_sch_pcb.pdf&x=28&y=15
Thank you in advance.
Sziasztok!
Fent nevezett Sony TA-N9000-es csodaszép végfok került ma a kezeim közé.
Hibajelensége, hogy bekapcsolás után a "Standby" led elkezd villogni.
Gyors ránézésre volt csak időm, de elsőre elkeseredtem.
Majdnem minden alkatrész "Sony" típusú benne.
Szükséges feszültségek első mérésre rendben
Alkatrész teszterrel végigmérve a tranzisztorféleségeket/FETeket és diódákat úgy néz ki minden rendben.
Ellenállások elsőre jónak tűnnek.
Valaki nem futott bele véletlenül előélete során ennek a típusnak a "szériahibájába"?
Mivel a tulaj elmondása szerint kb. 4-5 évente volt ugyanilyen hibával "javítva", bár utólagos forrasztásra utaló jelek nem láthatóak a panelon.
Köszi,
Krisztián
