iPhone 6 not turning on. the cpu gets really hot
the cpu is heating up, there is probably a short somewhere around the cpu or in the cpu itself. how can i measure components with a multimeter to see which of them is the problem. i read somewhere i can't use a multimeter to check resistance because it will pass 9V and the components will fry is that true? if so then what should i measure for?
thanks

I am not sure where you heard this, but it's bogus. You did not tell us if anything happened to the phone or if this just all of a sudden started. What have you done thus far?

the phone got smashed pretty hard. i removed the shields around the cpu. once the battery is connected and i turn it on the cpu gets burning hot until i disconnect the battery. i didn't do anything beyond that yet. i searched around the internet a bit, it might be the power management ic but i'm not sure on how to check and make sure thats the problem before i go ahead and replace it.

You used a new battery? Checked for any visual damaged on the logicboard after removing the EMI shields?

yes i used a new battery it's not that. no visual damage on the logic board, it actually looks really good, nothing damaged or burnt. also cleaned it with isopropyl alcohol and the short is still there and the cpu is heating up.

Post some good images of your logicboard with your question. that way we can see what you see.
