Faulty light autopsy with "electronic noise" on the video.

I recently smashed the screen on the phone I normally use to record the videos, and this video was recorded after fitting a new third-party screen (complete with the word "Moto" blacked out.)
It works as a screen, but there's now a noise issue on the audio, so I probably won't be making more videos with this phone. My apologies for the annoying electronic noise in the background. I'll check out the screening inside, but I think the issue is the screen itself.
This is an autopsy of a faulty rechargeable PIR light that won't take a charge.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
