It's not one phone. Theese are several phones from different users, they came to me just dead with equivalent simptoms.

PA ...PA ....10000000% PA.
There are 2 PA at top of the board. 900 and 1800, one of them SHort Circuit.

Repaired almost 15 phones this month

Hope help

Yo GEne ,first look at the RF signal procesor and then check the FLASH if the flash is damaged you need to replace it ,When the flash is wrong you can never flash the phone with nothing.

Ps. but check your cables too.

Gene · 03-27-2003, 11:07

This is not PA. 100%%% I just changed both to 100% working but phone still no power on.
I'll try with RF processor again but i think that will be no result too.
