Sziasztok 
Lehet ennek kalkulálni a kódot, vagy ha kiolvasom a memót abból meg lehet tudni.

Hello to everyone!
Thanks in advance if someone can help)
I have a problem with replacement of malfunctioned final amplifier at Cascade BE7944.
It is play sounds through front loudspeakers with distortion. 
It is not a problem with wires (I have tested it them with ohmmeter) and loudspeakers (brand new).    
I have replaced with Traffic pro and it worked fine.
Radioengineer has announced the verdict - problem with final amplifier and it is must be replaced, and preferably with service manual or schematic, which I do not have. And I did not allow him to unassemble my Becker just "for to watch how it is looks from inside")  
The problem is following:
1. Do someone have and can share with me with service manual or schematic of Becker Cascade BE7944.
2. As far as I understand BE7944 is further development of schematic Audio 10 ECE Typ 6011 (or 4011), which service manual is available at Internet - can I use it as general background for BE7944?
3. At present time unfortunately there is no possibility to find original MLT TDA 7454, only CHN or unnamed versions. I do not want to install that, but according to datasheet for TDA 7454 it can be replaced with TDA 738 *. And TDA738 * can be raplaced with TDA 7560 or TDA 7850 (in my case TDA 7851 L). If it is possible to replace TDA 7454 with TDA 7851 L and with which modifications? And will I not lose the “Backer surround” function? 
4. Any other suggestions? Please withought "sell this dinosaur"
 I have written to Harman / Becker with this problem but still no answer ...   
Thanks to all!
 

Üdv mindenkinek.
Adott ez az autó amiben gyári cd van de erősítőt szeretnének bele rakni de a fejegységen nincs rca kimenet,az lenne a kérdésem hogy ehhez a tipushoz lehet e kapni rca adaptert vagy marad jelszint átalakító?
Köszönöm.

Sziasztok. Sikerult atveretnem magamat vasarolvan egy ilyen bluetooth-os auto hifi-t. Beuzemeleskor a kezelopanel 2 gombjara reagal csak. Megneztem a leveheto elolapot, latszik, hogy valaki mar kibontotta. Ehez a modelhez nem talaltam rajzot, csak a 3800-ashoz, de a gombok bekotese nem egyezik. Idokozben ratalatam egy masik hirdetesre, ott mar hibasnak hirdetik ezt a 3900-as modellt, es ugyanazzal a hibaval: 2 gombra reagal csak. Ez szeriabetegseg lenne? Ha talakozott mar valaki ezzel a hibaval, meg tudta javitani?
