Should I contact ifixit for a replacement battery?

This could be numerous things. Did the device turn on before you put in a new battery? Is there any liquid damage? Have you double checked to see if you maybe received a defective battery? Also, check to make sure your LCD connection is good, sometime this can come loose and won’t turn the screen on, probably a long shot on that one but hope fully it is one of these. Let me know. Thanks and have a wonderful day!
