Audiowox VME9312TS DVD-lemezt nem mindig játsza le, új fejjel.
Sziasztok!
Még decemberben került hozzám, azzal a hibával, hogy tel mute, és nem tudtunk tovább menni, de itt hagyták és nálam bekapcsolt. Kipróbálva a rádió szól, de a dvd-ét nem játszotta le, mindig azt írta BAD DISC, rendeltem hozzá fejet, egy- két lemezt lejátszik, a többire azt írja mint előtte. Fej cserekor a három csavar beállítását nem biztos hogy jól állítottam be, ami a fej mechanikát fogja, minden csavar alatt van rugó, és hagytam lógást is, mert ezt pont szétszedésnél nem jegyeztem meg a csavarok behajtási mélységét. Mennyire kellene betekerni a csavarokat, hogy pontosabban vigye a dvd lemezeket? Előre is köszönöm a segítségeteket. Egy másik mechanikát lefényképeztem, de ebből hiányzott a fej, a rossz lett beletéve.
Help with repair of 6 disc CD changer for a Nissan Frontier 2001
I have a Matsushita 28185 9Z600 CD 6 disc player from my 2001 Nissan Frontier. It also has a Ref No. CQ-EN8060Z and I really need help with the mechanics of this unit. My 6 year old grandson knocked it off my workbench and a part flew out of it and I have no idea how or where it fits in. I think it is the thing that moves the CD's in and out because it opens up and closes back like it is designed to grab and hold something. Has anyone ever taken a similar CD player/radio apart? It looks so simple but for the life of me my brain just will not solve the puzzle. I have never been good at doing puzzles anyway, the pieces all look alike. Thanks for any help in advance. Please stay safe during this pandemic. Ralph         Coinhunter@Charter.net
Toyota TM4200 (Panasonic) autó rádiómagnó folyamatosan oda-vissza játszik
Üdvözletem Mindenkinek! Adott a címben szereplő autórádió, ami a kazetta behelyezése után folyamatosan oda-vissza játszik. Az egyik oldalról lejátszik pár másodpercet,majd vagy átvált a másik oldalra vagy csak egy keveset előre teker és megint lejátszik pár másodpercet. Folyamatosan ezt csinálja. Az orsók forgását ellenőrző optika működik, az ínpulzusokat adja. Ha esetleg van valakinek valami ötlete, vagy már találkozott ezzel a hibávalés tudna segíteni,azt megköszönném.
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!
