Phone went off few hours after battery replacent.

Hello there. Two days ago i used the guide to replace battery. I used 99,8 isopropyl alcohol to remove the adhesive. I used syringe to pour carefully and waited till i remove the battery. After that i replaced with the new battery (original samsung). I put everything back as the guide asked. I powered my phone and everything worked fine. I used it for 6 hours and then i went to sleep. In the morning my phone screen was dead. When i press power and volume down i feel a vibration but nothing else. Any ideas?

Answer this question I have this problem too

Is this a good question?

Hi

What happens if you connect the charger, does the phone indicate that it is charging?

Can you turn on the phone after a little while (to allow the battery to charge a bit) with the charger on?

You may have to open it up again and check your work and that the connections are all OK etc.

After the battery replacement it worked fin for 7 hours. Today the display showed some green horizontal lines and nothing else

Doesn't mean that something didn't come loose after it worked for a while.

I would check the display flex cable connection and also perhaps clean the cable end with 99.8 % IPA just in case handling it caused a bad electrical connection e.g. perspiration from fingers etc which prevents the screen from working properly
