Second doorbell in 2 years with different issues.

Originally I had the wired Lorex doorbell and to save you the headache of what is a long story it stopped working. Support was no help and they refused to cover it under warranty because they wanted a picture of my doorbell transformer. Unfortunately idk where my transformer is and it appears to be behind a wall somewhere. I told them that I was not putting holes in my wall for a $90 doorbell.

I replaced the wired doorbell with the 2k wireless doorbell but continued to have it wired to avoid needing to charge it. Everything was working great until yesterday I noticed the doorbell wasn't on. I figured that the battery possibly died even though it was hardwired. I took of the doorbell and plugged it in. The doorbell started charging and eventually reached 100%. I went to go wire the doorbell back to the door and now it doesn't turn on. If I hit the reset button the doorbell turns on, rings, motion works, and I can see everything in my app. That lasts for a minute before the doorbell turns off again and I need to hit the reset button again.

Any suggestions?
