BB Playbook Missing Part - no PC-USB Charging - no USB-data connection - GSM-Forum

fa3r4 · 03-21-2014, 01:09

Hello,

I have a Blackberry, that has a broken/missing Part. Its the second part after the usb connector. Its only connected with USB DATA- and USB DATA+.

Does someone know what's this part? I guess a capacitor, does someone know if its replaceable with another one? Or what part I can use for a working usb data connection.

Charging with a normal power plug works, but not connected to a computer. The massmedia mode/data connection also doesn't work.

Any ideas how I can fix this? Or what part I need to buy?

*I cant post links, or upload images. Try to replace the [DOT] with "." (without "")

this is couple of inductor, not capicitor. You can replace it with any inductor for USB-coonector from another mainboard, or simple solder short them.

Hello. Thanks for your help.

I already shorted the pins. (I think for charging it need to be, or it would not charge with the charger).

Does it matter witch inductor I take from another mainboard (or the specs)? Anyway I will try a couple of smd inductor from old mainboards...

post result when you done ^^

Sorry for the Delay.

I tried to replace it with two single inductors with each around 1,0-1,3 Ohms. The original double inductor i guess had something about 2,3 (+1 Ohms.).

It didn't work. It stopped installation on the computer after the recognition of the tablet.

I will give it a new try as soon i find some match able inductors.

Or will it be possible to connect two 1Ohm conductors in series to match the 2,x ohm (like connection two resistors in series)?

what are you seeing at battery icon in PB when you plug USB charrger or connect with PC? and what's the PC say when plugged?
Check again the 4th pin at USB-connector at your PB, if it short with Gnd (less than 350ohm), try to cut it at PCB. This will enable USB-OTG at PB and PC will not recognise PC (but PB's OS not support OTG). I will take picture as soon as I could

what's Khatiger say is right inductor value is not so important,its used to filter high RF signal.Do as per jpg

Thanks both to you.

I checked OTG its not shortet with GND. I only shortet pin5 (GND) with the Housing from the connector.

I also soldered a new connector.

I will remove the ESD IC.

here the acutal state...:

As soon i have 10 Posts i will edit this dump posts with no working links and attach the images.

connected to PC:
Nothing at all. Its like not connected. No charging symbol.
Windows shows unkown device. The Blackberry device manager starts, but then it stops after the installation attempt.

connected to USB-Charger:
shows icon, charges fine.

now check both DATA+&DATA- lines with ohms meter (multimeter) value are almost equal by minor difference.If there is vast difference than data line is not working according to pc require.If so than it is impossible.bcuz no schematic.
Also test that insert any pendrive using its adapter cable and check in file manager, do it show any external drive.If yes than also you can't do any thing bcuz pc connection lines and OTG lines control ic not working, where its located ask some master for schematic or jpg.

one request pls.. upload photo after cleanning well very ugly photo.
sorry.......
