DEAD MTBox(blue) HW v8.4 Need Help - GSM-Forum

free1600 · 02-05-2011, 11:16

Hy all ,
I have a dead MT blue version HW v8.4 .
No lights at all when connect to pc.
If I sort out the card then ask for drivers and installed them .
I can get this :

Device:<\\?\usb#vid_a550&pid_f00d#123456#{e6ef7dcd-1795-4a08-9fbf-aa78423c26f0}>
<App:CR><Version:01.02.0001>
<SN:SCARD NOT PRESENT>

If I put the card then no connection at all :

Can't find device

On D3A I have 3.5v
On D2A I have 0.2v
On D1A I have 0.25v
I have seen some one tells to change the D1A because must have 5v there ?
I checked the PCB tracks , zener diods ,resistances ,capacitors(1 capacitor not work)I don't know his value .
Somebody can assist ?
