Turns on for a second, then shuts off

Well, actually ended up taking it apart, thinking it was broken anyway! Find that the connecter to the top 4 buttons to the main board had some corrosion on the cable so I tried cleaning those up a little bit. I had to snip the ribbon cable tip off just a little bit but Putting it all back together. I accidentally ripped the ribbon cable at the connecter. so I thought, “well I’ll just try to shave a little bit of the casing off..” using a metal blade I must have completed the power circuit cause it turned on! I kept going and sure enough, pairing mode triggered and I connected to my phone and works like normal! Even tho the power/bt buttons aren’t connected! Lol know where to get a replacement ribbon cable?!
