T610 water damaged - GSM-Forum

Hi!

I have a T610 that is water damaged. I've cleaned the PCB and all was ok except that the phone didn't always connect to the network and if I turn on the GPRS the signal drops and the phone is restarted.
I reflown the PA and antenna switch (as I thought that was wrong) and now the phone is totally dead (when I put the battery the red LED lights up short) and it doesn't even connect to DIV8.4 (the progress bar remains at 0%).

Should I reball some chips?? What can I do to revive the phone??

Thanks

@andreic

You have for sure been reflowing the PA too much, and have resultet in a short. Try to take the PA off the board and see if the phone powers on. Id yes, then you knwo whats wrong.
