How can I make this phone turn back on!

OK this is not a simple press the power button for 10 seconds fix , i know what I am doing but this is beyond my experience so I have come here. This phone had water damage it’s not mine so I can’t tell you exactly what happened…..i have never messed with a logic board before so for my question ….is it possible to replace something on the logic board to make it work again or do you have to buy a new logic board and lose everything . It’s like the phone is completely dead so either it’s not getting power from the battery to make it turn on or there’s something else going on …….

things to mention so we don’t waste each other’s time .

I don’t need a screen
i don’t need a battery and yes the battery has some juice
I tried iTunes
of course iv done a hard reset

Yes it is possible to change a part on the logic board which could bring the phone back to life. But to do this you would need the proper equipment and experience as first you need to know which line is faulty and what component on that line is faulty. As for replacing the logic board it would be easier to buy a second hand iPhone 6. It would work out about the same price. However if you have already brought parts for the one you have it wouldn’t hurt to buy just the logic board but make sure the original home button comes with it.

Could you go into more depth with this ...

The person I’m trying to fix this for really wants to be able to save the photos so if I get a new board it will defeat the purpose of trying to save it . I already told him I probably could not fix the logic board because it’s not a DIY task lol but I’d love to learn

@wtderrick25 If the person needs there data from this phone it is best you stop after ruling out parts. If you want to learn you can start by purchasing:

• some parts phones from eBay

• DCPS

• Microscope

• Soldering station.

• Hot air station.

• Multimeter.

• Board view software.

• Schematics.

You will need to learn the functions of all components on the logic board for example: Capacitors, filters, diodes, resistors, coils, mosfets and the IC’s. You will have to learn to microsolder and know how much heat can be used without damaging surrounding components. You will need to be able to re-ball IC’S and that’s only a start. These skills are not acquired overnight and sometimes take years to master.
