3gs not turn on,charged and recognize by itune

I've replace the battery (new battery has 3.7V) and dock connector assembly, but with no luck. Iphone still not turn on, no battery sign when connected to charge adapter, and still not recognize by PC.

All connectors seems attach to the board pins properly.

How long has this been going on? Did anything happen to the phone? Did it get water damaged or did it get dropped? When you say you replaced the dock connector assembly, how did you do that?

I never use the iphone for almost 2 weeks.

It never dropped or get water damaged. I replaced the dock connector by taking all the assembly and replace with the new one I bought thru ebay.

I think your motherboard would have short circuited.

Why don't you check it using a multimeter?
