This radio is to a 1970's MG/MGB vehicle. Its using an older 14 Pin DIP IC to
do the FM stuff, its marked T2D. Cross ref comes to a NTE723.
If I put my metal probe on pin 9 or 10 (detector) I can hear a local FM station playing,
but the tuning has no effect.
I have 100 ohms from pin 9 or 10 to gnd. Pin 3 is seen directly tied to gnd, and pin 4 also reads short to gnd
and there is no DC volts on it also no dc volts on pin 5. I can see no dc volts on any pin I probe. Is the IC bad?
Its not getting warm for short and current draw on the PS is minimal.
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!
Sziasztok!
Egyik barátom keresett meg ezzel a ford gyári fejegységgel. Használtan vett kocsi, akkucsere után derült ki hogy a rádió kódot kér. A szerviz a papírok bemutatása után 10.000 Ft-ot kér a kód megadásáért. Ez azért kicsit soknak tűnik, mivel nekik pár perc lenne kikeresni az adatbázisból.
Megígértem hogy kiolvasom az eepromból, de sajnos a kód az MCU-ban van. Ilyent még nem csináltam, és nem akarom elrontani a készüléket - akkor inkább menjen a 10 ezres kódmegadás a szervizben.
A sorozatszáma M006142. Ebből is ki lehet nyerni online kalkulátorral, de ez is fizetős és szerintem nem elég megbízható ezért nem szívesen fizetnénk nekik.
Melyik megoldás lehetne az egyszerűbb?
Esetleg valaki ki tudja a sorozatszámból deríteni a kódot?
Előre is köszönöm!
