We show you all the essential power rail and IC voltages you need to test with a multimeter. #Pixel4XL, #DeadSolution, #VoltageTesting, #MobileRepair, #GooglePixel, #BoardRepair, #sanyomobile Is your Google Pixel 4 XL completely dead and not responding? Before replacing ICs, you must perform a proper diagnosis by checking the input and output voltages. In this expert 2025 tutorial, @sanyomobile provides a complete schematic guide to all essential voltages for a Pixel 4 XL dead solution. This advanced guide is critical for technicians worldwide, especially those serving clients in high-value regions like the United States (USA), Canada, United Kingdom (UK), Australia, and Germany. We will guide you with a multimeter to check Vbat, VPH_PWR, and the critical input/output voltages of the PMIC (Power Management IC) and Charging IC. This is the professional way to diagnose a short circuit or a faulty power IC and find the exact point of failure.

A: Always start with the basics. First, check the Vbat (battery voltage) at the battery connector. Then, check for a short circuit on the VPH_PWR line. This video will show you the exact test points on the motherboard. Q2: What are the normal input voltages for the Pixel 4 XL PMIC (Power IC)? A: The main Power Management IC requires specific input voltages to function. We will show you the key power rails that feed the PMIC and what their voltage readings should be on a healthy device, helping you determine if the issue is before or after the main power IC. Q3: How do I know if the charging IC is working correctly using a multimeter? A: By checking the input voltage from the charger (VBUS 5V) and the output voltage from the charging IC, you can quickly determine if it's faulty. We provide the test points and expected readings for the charging circuit. Q4: What are "output voltages" and why are they important for a dead solution? A: After the PMIC receives input power, it generates multiple lower "output voltages" (e.g., 1.8V, 0.8V, 1.2V) that power the CPU, memory, and other parts of the phone. If these output voltages are missing, it often points to a faulty PMIC. Our guide covers which ones to check. Q5: Can this guide help if my Pixel 4 XL is short-circuited? A: Yes. By checking voltages at different stages of the power-on sequence, you can isolate which power rail has the short circuit, making it much faster to find the shorted capacitor or IC.
