lpd8 repair
lpd8 repair Posted on: 26.09.2011 by Sam Hanno have a buddies lpd8, trying to use it for effects in traktor scratch, but the usb port is broken off. the port itself is in good shape, just broken off its mounting points on the board. when that happened, it pulled up the solder pads on the board as well. is this fixable, or is the board trashed? | |
| Megan Konarik 07.12.2012 | Hello, I repaired mine just a bit more than a month ago but yet forgot the right places for cables. I'll take a look toevening . If I forget to do, just re-post in a couple of days. But I guess that if I wrote for everybody that: "the white cable on the left of the R1 resistor the green cable on the left of the R2 resistor" ... it must be what I did. And the device work perfectly. Don't worry to much with the fact you don't feel quiet about doing it by yourself. Because of two things: - if you don't try to fix it, your device is still good enough for one thing: land on the trash. So you don't have nothing to lose (no more). Really. - and it's not as difficult as it can seem. I allow myself saying that because it was for me the first time I soldered as thin. And I was really surprised when I plugged the device and it lights up. You just need to be calm and don't try to go too fast: prepare everything you need, take space enough, take your time, breathe, and it will be alright. Note: you really need a good soldering iron (warm between 230 |

So I would like to thank everybody here and hope this will help many in the future. |

| Keiko Luginbill 07.01.2013 | Such a shame that this otherwise excellent device is spoilt by a simple design flaw. The USB connector is fixed to the mother board by the most tenuous of connections and snaps off with the slightest out-of-line force. It is officially un-repairable - ruined by something which would have cost nothing to manufacture properly in the first place. One hates to believe this kind of thing is deliberate, but surely any kind of field testing would have shown up this problem. Another electronic device consigned to the trash can for no good reason. |

| Jetta Drenzek 07.12.2012 | Sorry to revive a dead topic, but I've had this exact same problem after only owning my LPD8 for a grand total of 3 weeks. Akai customer service have responded with a giant foxtrot oscar, and so I'm left to repair it myself, which isn't a problem since I have all the tools and skills needed to do it. However, the pictures don#t show clearly what the white and green wires are going on to. At first I thought white was going to R1, and Green to R3, but then it looks like white is bridging R1 and R2 and green is bridging R2 and R1. But then the post above says the green cable goes on R2. But it definitely looks it's soldered to R3 on the picture. Can anyone shed some light? (Last time I buy an Akai product, second I've owned, second that's broke within two months of light usage! They need to sort out their quality control department) |

| Sam Hanno 26.10.2011 | the pads from the usb port? those have lifted up, but I'm not trying to replace the port. I'm trying to hardwire a usb cord to the board, like djheir's friend did for his lpd8 (at least it looks like it's hardwired. just double checking which points he soldered each cable (vbus, d+, d-, ground) to. |
| Yong Aptekar 25.10.2011 | I can't see the photos large enough on my blackberry, but check if any of the points that pulled off of the board have not lifted up. You are looking for a copper pad that has been separated from the circuit board. If you have any that are lifted, current may still pass through, but not correctly. Hopefully you can't find any lifted pads, if you do, you can't fix them... |
| Sam Hanno 25.10.2011 | alright found my iron and some solder. can anyone confirm that gnd and vbus are soldered to either side of the small tan box there (on mine its black and says "100 10V") and that D- and D+ are soldered to R1 and R2 respectively? thanks |
| Arcelia Siebeneck 07.10.2011 | I did that already - there's definitely current passing through the pots... I believe it's a problem elsewhere on the board... |
| Lisa Lochotzki 07.10.2011 | It sounds like there's no longer +5V (or else voltage) on your pots then. If you know how to use a multimeter, measure the DC voltage accross the POT, the first and the third pin. Should be at least 3.3v. If there's nothing there... you need to find where the power fail, could be a simple open-circuit ferrite bead, or a broken circuit trace. |
| Arcelia Siebeneck 06.10.2011 | I killed an LPD8 recently... all the pots don't work anymore (but the buttons do). I've got no idea what I did but I've tried everything to get it working again |
| Lisa Lochotzki 06.10.2011 | fit a powered usb hub in between for testing purpose... worst case you'll blow the hub or it's powert supply. And it's doable, I did it a couple of times. You just need some patience and tiny wires |
| Sam Hanno 06.10.2011 | ooo boy. time to put my novice soldering skills to the test...good thing there's no loss other than a an old 3 ft usb cord if I totally screw it up. I really hope it doesn't blow up my computer when I try this |
| Evia Neuzil 05.10.2011 | I snapped some pics last evening
with my phone. I got as close as I could so hopefully this helps you some |
| Sam Hanno 26.09.2011 | that'd b awesome if you could without damaging anything. i was going to just borrow it until it turned out to be broken today, if I could fix it maybe he'd just let me have it, and i get a controller for the price of solder :P did your friend solder a new port on, or did he solder the port on inside and then solder the cord to the port permanently? |
| Evia Neuzil 26.09.2011 | Exact same thing happened to my pad. I suspect the kids knocked it over and it landed on the usb jack while a cord was plugged in. I had a friend of mine who's good at soldering take a look and he found that there's no way to get the plug back on. He actually ended up tracing the contacts back to somewhere else on the board and soldered a new usb cord on there. I don't know anything about soldering but let me know if you want me to crack it open and take a picture for reference. |
