Üdvözlet Mindenkinek!
Egy ismerősöm hozta a fent nevezett készüléket,hogy szeretné beszerelni a Nissan Micrájába. Az autóban jelenleg egy Sony 1 Din méretű cd rádió van,eredetileg Nissan Blaupunkt 1 Din méretű ISO csatlakozós készülék volt. A Clarionhoz megkaptam a csatlakozókat kb. 30 cm vezetékkel. Letöltöttem az SM-jét a tanyáról, asztalon bekötöttem a tápokat / akksi,gyújtás,test/. Bekapcsolva a készüléket a következőt írja ki: Check TH12HW, INVALID EQ. Segítséget szeretnék kérni a bekötéshez, hogy használható legyen. A Micra 2006-os évjáratú 1.2 benzines.
A válaszokat előre is köszönöm mindenkinek:Misi
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!
