Hi, I was scraping off back glass on iphone and scraping tool slid under wireless charger pad and caused a scratch to appear on the back of logic board. The phone no longer turns on could this be the cause or could it be a damaged power flex cable that I also may have scratched, I don’t think it is the latter as if it was the power flex cable the phone should switch on when plugged into a charger?

@albert123456s looks a bit chewed up ;-). See if you can remove the heat shields/stickers etc. and let us see the components underneath. Going by the pictures you posted ( a bit dark and a bit hard to see) it looks like you have some damaged components. If so, you do realize that this repair will require some special skills and special tools to get it done,
