Repair instructions and ASK Logik7 from the E65!
Good day,

as you all know I am going to repair a defective Logik7.
I just wanted to show my work and presentieren because of the many questions that I'm not yet as far : Thumbsup:
Come rare in the hobby room at my in-laws.

Picture # 1: Here's the Logik7 board, you see four stages
1x Center speaker
1x both rear doors
1x bass left
1x bass right
Picture # 2: I've removed the old broken amplifiers and exposed contacts.
Image No. 3: The same close-up
Picture # 4: These two stages are to replace the old
Picture # 5: I was looking something Sprittig ;-)) do not have hands trembled, but I did not want to hide from you!

I
I also soldered the amp already part way to the board (or
no photo), for the speakers I have 0.5 mm ² thick and 3cm long lines used for
the signals of the thin black? mm ².

Will keep you here with that Fred up to date.

mfg odd ....

Edit of 19/03/2012: As I already wrote yesterday, I was
sprittig something and so I said instead of 0.5mm ², 1.5mm ² to
the TDA soldered ;-( (Now I know why it was so hard * LOL *

This will, of course, correct and add new pictures!

THIS IS HIS 2'ND POST


So

I was now again in the basement and I studied the board.

If you want to use an external amplifier, for which I have marked the low-frequency signal.

If you simply want to repair his Logik7 that will please the TDA1562 as specified soldered to the motherboard.

I assume no warranty, all work is done at your own risk!


Who is a benefit sional repair wants, which is aimed to please the user: "King.reparatur" from the other forum!

I feel the effort is too great and I do not want to operate commercial is.

I only went about creating it and prove that a repair is possible in our Logik7


ALL REQUESTS FOR JOY WHEN REPAIR

FIG 1: Instructions

FIGURE 2: it should look like it! (Thermal grease and do not forget to drill)

mfg odd ....

More to follow ....... O lines





I hereby publicly thank you for the user from the Russian dj0vitamin BMW forum ( www.bmwclub.ru ), who has developed a similar guide own un told me his knowledge

HIS 3'RD POST

Have now labeled this.

So much fun with it : Thumbsup:

HP. Here you can see how difficult it is to enfernen the old amps without damaging the contacts

The connections are labeled with base, emitter, collector (abbreviated diagram by the letters B, E, K)

thanks

Nice find paper....someone needs to be the guinea pig and let us know how it goes.

Excellent find bro!

That's because I have no clue what was written but I will take it to my electronics guy and I am quite sure he can decipher it. It funny as I just received my Logic 7 amp in the mail today after sending it out for repair. It it works then that will save me on future repairs

I just checked around and seem like no one have them chips...

Nice find. I did a similar repair to my SID (Saab Info Display) albeit way less complex. I hope I never need this info but nice to know it is out there. I hope mine lasts since it is not on the CPO dime.

dont know what 96% of any of that means but i sure wish i did.

basically it's instructions on which chip to remove from
the logic 7 , & which chip to replace it with .
Also the soldering points are given .

I did some research the BEK transistor KT3107 it's Russian
TDA8564 and TDA1562 u could find them all on eBay

Nice find. Just sent mine off to Becker for repair. Now we have instructions on the repair. Very good find

I bought all the caps all the transistor all amplifiers can't wait to get back to NYC to dive on this put the marine corps electronics knowledge to work

Yes , I seem to have ran into that same wall. A company on the away coast just informed me that they can't locate a chip that is needed . I believe Paper is onto something. Must investigate into it further. Mean while no sounds ! :mad:

This is some crazy info. I wish I really knew what to do with it. The shop on the west coast has yet to tell me what chip it was that they couldn't get but i would think just like I found it in eBay and the site you posted I would think by them being a big company. However if I need to get the oart and get it to them Ao be it. I may need that unit if its still availabe. I'm 3 ask units in the hole. Lol

Great find, I will be definately ordering the chips as my drivers side bass seems to crackle a lot.
