**iPhone 17 Dead? Tech Masters Canada Fixed a BB PMU Short and Saved the Customer's Data**
An iPhone 17 came into Tech Masters Canada completely dead: no boot, no charge response, no signs of life. The customer's biggest worry was losing their photos and files.
**Our process:**
✔ Ruled out the basics: battery, charge port and display
✔ Monitored current draw on a DC power supply and found an abnormal draw
✔ Isolated the fault on the logic board: a **short on the baseband PMU (BB PMU) power rail**
✔ Repaired the fault at component level
**Result:** The phone powers on and works normally, and **all of the customer's data was saved**. No replacement phone, no wiped storage.
A short on a PMU rail can hold the entire board in a fault state, so the phone looks "dead" even when the battery and screen are fine. Board-level diagnostics find the real cause, and the fix often costs far less than a new device.
