Shows apple logo for 1 sec and then goes black?
I have replaced the loudspeaker on an IPhone 5s...
The phone worked well before, the only problem was no sound.
Now it wont boot into IOS.. When i press the on/off button, it shows apple logo for 1 sec, and then screen goes black. But i can see that there are light in the screen (on the side when its not assempled),
If i try to start it by holding the on/off button, it shows the logo for 5-6 seconds and then goes black.
I have tried to go to recovery mode (or what it is called), but it wont let me.
Now i have replaced the bottom cable, with jack, charger and microphone on... Still nothing happens..
I have tried to connect a broken screen, but also with the same result.
The only thing i now believe it could be, is the battery. The first time i changed the part, i took the battery out. And when i was trying to boot the Iphone, i said that there was no power on, but the phone was fulle charged before i started.
Could it be a damaged battery??
Or is there someone that have an idea of what else could be wrong???
