Black screen pinging sound when on charge.
Hi,
I recently managed to revive my daughter's water damaged iPhone 5, but it was suffering with intermittent signal problems and after replacing the screen, it wasn't responsive all the time.
I bought another iPhone 5 that had a damaged logic board, but "all the other parts worked".
Using the guides here, I removed my daughters logic board and put it in this other phone.
Now it won't turn on, and when plugged into the charger, it just pings every few seconds. The screen does not light up.
I thought that I might have damaged the screen flex cable, but both the screens I have, have been tested on another phone and they both still work. I have slao tried both batteries in the phone but still no luck.
I am going to strip it down again, but apart from the screen connector and the battery connector is there anything else I should be looking for?
Thanks
