Urgent ! Repair / Service Manual for PUSH2

[koljabeckmann]

My Push 2 has a defect Chip (U15), directly behing the usb port. I need the partlist to exchange the chip.

Is there a partlist and/ or service manual avaible?

I tried to resolder - because for whatever reason the pin1 is corroded - though this device was only once used for a gig - but that didn't seem to do the job. Its likely a voltage controller/converter for USB 5V<->12V, but there is only WR89 printed on it, which i cant identify.
The unit does power up over charger and shows the display but cant connect via USB.

Did you get this sorted.

I also have a dead Push 2. It powers up so you see the logo, but its not recognized by the computer. I suspect its the USB port but nothing obvious.

Hey bro, I contacted the support, but no reply so far. Thats really disappointing.

AKAI has their service notes on the net. I am surely not gonna go for PUSH3 when they dont have dervice notes.
I mean there is a voltage converter for 0,05 EUR broke and I cant exchange it, because their are no service notes or they just dont reply.

This is horrible service!

And its their fault anways - its clearly bad soldering which coroded over the years.

If they do not answer Ill go with Akai Force - if they'll do Ill give you a notice.
