While we are happy to help, the shipping alone on this situation is going to cost a lot of money.
As you have spent some time in our forums, you can see that there were some problems with the 1900's that we have since fixed the majority of issues with this update. Your problem however, seems like it may be hardware related, and is very rare.
While I understand that this is hearsay at this point, buying electronics overseas or from foreign countries is always not recommended. I purchased an iPhone in the USA and brought it to China while living there for awhile and ran into the same problems that you are.
As for what can be done now, if you think that the issue is most likely related to the power pin and you likely won't be sending it overseas for repair, you can try opening it up and soldering the points of the power pin to the board.
The pin being loose is usually related to an impact onto the power pin which dislodges the soldering points from the board. If you are feeling adventurous about trying this, PM me and we can go through it together and I can try to help.
