My screen won't turn on after replacing the battery

Hi people of iFixIt

I searched the other forums with similar questions, but I didn't find an answer.

My device was working fine, but then one day the iPhone would not get pass the low battery bar. If I plug it in, it just tells me its charging. Unplugged, it tells me to charge it. Yes I have tried it for 24 hours already, and this phone has been like this for the past.. 5 months?

So I have decided to buy a replacement iPhone 5g battery (they told me 5 and 5g is the same).

I put in the battery, and now the iPhone can be seen on iTunes, unlike my old battery.

However, there is no backlight behind the screen. I Yes I made sure the display connectors (not sure what you call it, but i'm talking about the one with the three connectors) were fully in.

No, I do not see any faint apple logo. There is absolutely nothing but a black screen. It doesn't even vibrate when I switch the vibrate button on ( or off, what was it..)

Please help me,

Thanks,

Rin
