Becker Cascade BE7944 need help!

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!
 
CD 30 MP3 autórádió időnként elhallgat
sziasztok: megnézném az alaplap forrasztásait, de nem tudom kiszedni. Az előlapot kiszedtem, de a gyanús a Kép43A ábrán, a hűtőbordán látható 4 db 5mm-es lyuk, olyan, mintha csőszegecs lenne. Antenna és csatlakozója jó, amikor elhallgatnak a hangszórók, a kijelző világít, mutat. A gyereké, egy 11 éves OPEL Astra G-ben van Szedett szét ilyet valaki, vagy csak erőszakosabban kell bánni vele? Bálint
VW Tiguan olajcsere intervallum nullázása MEGOLDVA
Sziasztok!
VW Tiguannál hogyan lehet kitörölni az olajcsere intervallumot?
Köszi.
Grundig (Opel) CD30 MP3 autórádió magától bekapcsol? Megoldva!
Sziasztok, a tulajdonos állítása szerint az este leállított autóban a rádiót reggelre véletlenszerűen bekapcsolva találják. Ha jól néztem, ezen nincs gyújtás pont, csak direkt B+. Tényleg be lehet kapcsolni kivett kulccsal is, de ilyenkor adott idő után kikapcsol. Sőt a rajza szerint feszültségcsökkenésre is lekapcsol. Találkozott már valaki ilyesmivel? Előlapi gomb okozhatja?
Minden segítséget köszönök!
Laci

Vadmalacka javaslata alapján szétszedtem a CD loader kapcsolót, megtisztítottam, leápoltam az érintkezősávokat, összeraktam. A gép több mint 2 napja készenlétben van, egyszer sem kapcsolt be. Nagyon köszönöm a segítséget, a téma lezárható.
Még egyszer köszönöm!
