Hi to all,
I am looking many days for schematics for the LAX MA7200 audio amplifier.
I think it is made in far east and is copy of other model, probably a QSE brand.
Similar to this-or made from the same factory-is the ODY-PRO 7200, which has a board with a printed label "XILICA" which is a Canadian company.
Any of the schematics is great help for me, as I have to service more than 20 units.
In case you met any of them please inform.
Thanks for your time for reading
sziasztok--nem tudom itt a tanyan ilyesmivel foglalkozik-e valaki,de kellene nekem a renault 22DC461/62T tipusu kazonak a kodja, RN461FX6011436--FD0999026011436--7700 433 946 R003...elore is koszonom...
Sziasztok!
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...
Köszönöm!
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.
A fent említett erősítő került hozzám szerelésre. Nagyon szerencsés módon 220-at kaphatott a bemenetére, mert felrobbant a bemenetválasztó ic benne, és a vezérlő mikrokontroller, ami egyébként HD404222 névre hallgat. Lát rá valaki bármi esélyt, hogy szerezzek ilyen ic-t felprogramozva?
