Harman Kardon AVR151-171 táphiba MEGOLDVA


A címben említett erősítő tápja azt produkálja, hogy a STB 5V pulzál rajta, ha a front panel csatlakoztatva van, akkor a power led jól mutatja a jelenséget. Nem védelmi módban van, hanem tényleg mérve is, mászkál a táp folyamatosan 2-5V közt. Elkók esr-re, kapacitásra jók.  TF91 trafó és az IC91 névre hallgató pwm contorller is jó. Aki esetleg javította ezt a kapcsolóüzemű tápot, adhatna pár tanácsot, mert ezekben nem nagyon vagyok otthon...


Üdv.: Viktor


A hibát az IC92 pwm kontroller okozta, de jól meg is szívatott mert rendeltem a HQ-tól, még szerencse, hogy 2 db-ot, persze amit elsőre beforrasztottam halott volt, és el vitte magával az IC91-et is. Mindkettő cseréje után a táp elindult.
