Hey All,

I picked up an SMS lately, and it won't power on.

I opened it up bought a new regulator for it, soldered it in, and it still won't power on. I am not sure If I messed up when I soldered, and the voltage is still not being able to run through.

When soldering on the underside of the board, I may have left surface scratches on the board from my hands being shaky when handling the soldering gun, but no big gashes were made, would this affect the power on issue or should I just desolder, and try again.

It could be my soldering skills are not good, since it looks kinda messy.

Does anyone have any guides or tips for fixing the power-on issue, and how to properly desolder the regulator, and install a new one. I am not sure if I did it right.

thanks for the help
