Here are logic 7 repair instructions for every 1

OK I AM NoT TAKING ANY CREDIT FOR THIS .
I FOUND IT WHILE READING ON A GERMAN FORUM .

HERE IS A COPY & PASTE OF THERE INSTRUCTIONS WITH PIC'S
DO AT YOUR OWN RISK !!!



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 thick and 3cm long lines used for
the signals of the thin black? mm .

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 , 1.5mm 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.



TDA1562 datasheet: Page 3
http://translate.googleusercontent.c...DCfVr9q-GX5M0g


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

Important: Do not forget before discharging the capacitors. With a light bulb or a resistor.

Way to prevent it before it transmits when soldering

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

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.

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 !

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
