UNIT: Cherry Mobile D12

DIAGNOSTIC: Shorted phone.. P.A problem....

SOLUTION:

Since its a P.A problem it need to be replace with same type of power amplifier..

But i don't have same P.A so I've decided to make a jumper solution...

here's the jumper solution that i make...and it is tested by me many times in china phone with RDA 6231 P.A

here's my finished product:

Talk N Text and TM networks has a strong signal...

tested in receiving text msg

hope it will help...

Br,
Aermachi
