    Big problems and its getting worse

    Hi there,

    im new to this forum, while ive already read all posts that
    could help me with my problem.

    Ive got a PAL Wii (LEH169...) with a d2c chipset. ive bought
    a d2pro9 chip (blue label) and a wii-clip v4c. Ive soldered
    the chip onto the clip and clipped it onto the d2c chip.
    Then i got a constant red light with the wii reading originals
    (wii sports) and refusing backups (cant be read).

    i tried to solder the clk bridge, didnt help. i soldered j to j with
    the red cable coming with the clip. didnt help. clk bridged
    plus j bridged and vice versa didnt help, while i got the inching
    problem as long as j to j were wired together.

    then i tried to carefully remove the clip and replace it.
    nothing but red light. now ive discovered that one little
    transistor (the left one to solder point "c" on the wii pcb)
    has been removed and 2 little legs on the ic are bent down.

    the wii is still working but who knows how long?

    the first problem may be my own fault, as i was apparently
    not careful enough at removing the clip. the second one,
    hm, could it be a fake clip? but it has all signs of being an
    original plus a "genuine" sticker on the inner side.

    what should i do? as the solder on the j point, the
    missing transistor and the bent legs are clear signs of
    having opened my wii, i cant send it to nintendo.

    every help is aprecciated.

    hi again,

    the legs are okay again, dont ask why... ive done nothing
    to them.

    here is a photo of the pcb.




    of the clips back.

    It could be that the D2Pro9 may not be updated to the latest firmware. First find out from the reseller if they shipped it with latest firmware and what version they say it shipped with. The latest is 2.3 (H/W) and 1.6 (SPI). You could also goto the d2pro website and download the 1.6 utility disc which wne read by the Wii it will tell you the firmware versions.

    hey,

    thanks for the quick reply.

    ive already burnt the 1.6 disc, but as the red light wont switch to blue
    my wii doesnt recognize burnt discs. im using verbatim dvd-r, but the red light
    does tell me theres something wrong elsewhere.

    yes, to flash the firmware could be good, but i havent got a jtag programmer
    yet. does it have to be the original or could i build one myself?

    what to do with the loosened transistor? since its so tiny, ive got no
    idea how and if to glue it back on the pcb...

    from the pic it doesnt look like clk was bridged... though you stated you tried it, make sure it is bridged. dont solder j from chip to j from board if clk is bridged. You should fix the part of the board that broke, becareful in doing so, use tweezers to hold it in place, flux it and then touch it with an iron , do this to both sides so its secure. Inspect the chip underside with a magnifying glass to make sure that nothing on it is mashed. Use a thin blade to go through the slots to straighten things up.
    Since you have a d2c chipset, ask the retailer you bought it from if the firmware on the d2pro9 is 2.3/1.6 if its not then that would be why its not working. Get them to flash it with 2.3/1.6 firmware.

    if the task is beyond your scope you should really look for a professional in your area.

    hey, im glad to talk to professionals here.

    when i first soldered the clk bridge, the drive sounded different,
    e.g. not good, so i removed the bridge.

    im willing to try to fix the missing transistor myself. in case i dont
    succeed, i would surely call for someone whos more into microelectronics.

    what i dont exactly understand is: what means, to "flux"? im from germany so
    im not getting the exact meaning. you want me to solder the tiny transistor back onto the pcb? concluding from the fact, that it loosened that quickly, i would have thought it was just glued onto the motherboard. and to reach the underside in order to check it, i would surely have to disassemble my wii furthermore? phew, i think then its up to someone skilled to help me on.

    what slots are you referring to? hm, i hope its not as difficult as it sounds.

    You can't just use glue to stick the resistor back on, you would have to solder it on which is going to require precise handling. So if you have not done this type of soldering then I would leave to a professional otherwise you could end up causing more damage.

    yes, i think youre right. as i mentioned, the wii is still functional.
    but transistors are there to avoid unusual peaks, as far as i know.
    so it would be silly to use it as long as its broken. damn, i wouldnt
    have thought it could turn out so difficult.
    thank you so far for all your help.
    is there somewhere an exact guide to soldering tiny pieces on motherboards? just to be sure im unable to do it ;-)

    I dont have speakers on this computer atm, but video seems to be what I used to do for repair.
