Iphone shuts off randomly with camera and sound

My iphone shuts off when ever i try to take a picture and or when i get a notification that blinks the flash or speakers. The odd thing is it only does it when its unplugged from the charger. If it's plugged in , everything is fine. I have already replaced the battery but still does it.

I have ruled out the software as its been restored and DFU restored numerous times and on differnet computers and my phone is way out of warrenty plus i have replaced my screen myself due to it being out of warrenty

Does anyone have any advice on troubleshooting hardware? I am knowledgable in repair and modfication of electronics, can solder and use a multimeter/volt meter.

Thanks

Josh

Try having a look at iFixit.com. The iPhone is not considered user servicable. There is no such thing as a legitimate source for parts for an iPhone. Apple does not sell parts. The only possible sources are:

1. Salvaged from broken/discarded/stolen phones.

2. Fakes

3. Defective castoff parts stolen from one of Apple's suppliers.

Thanks for the reply. I plan on salving parts from other broken iphones, but i just need help verifying what exactly is causing the issue so I dont buy a bunch of parts and not fixt the problem.

Im thinking it has something to do with the logic board cuz it works fine when plugged in.
