Redmi note 9 dead DC reading 22 on struck. What next ?🤔🤔🤔 SGT mobile repair institute in Bangalore

In hardware repair, a DC power supply reading of 0.022A (22mA) on a dead Redmi Note 9 usually indicates a partial boot sequence or a hardware communication failure before the high-current stage. Likely Causes and Solutions CPU/eMMC Issue: A "stuck" low reading (typically between 20mA and 60mA) often indicates that the CPU has started the boot sequence but cannot communicate with the eMMC (storage) or RAM. This is frequently resolved by reballing the CPU or eMMC IC. Secondary Voltage Short: There may be a short or leakage on a secondary power line (like 1.8V or VIO). Check capacitors around the Power Management IC (PMIC) for shorts. Charging IC / USB Controller: If the device shows this reading when plugged into a DC machine but doesn't react to the power button, the charging/USB logic may be compromised. Software/Firmware Corruption: Occasionally, this reading indicates a device stuck in a "dead boot" or EDL mode because of corrupted firmware. Recommended Repair Steps Check for Computer Detection: Connect the device to a PC. If it is detected as "MediaTek USB Port" (MTK) or "Qualcomm HS-USB QDLoader 9008" without any button presses, it is likely a software brick or an eMMC communication failure. Verify Voltages: Use a multimeter to verify if the main power rails (VBAT, VPH_PWR) and secondary rails (VIO 1.8V, VCORE) are present. Reflow/Reball ICs: If voltages are present but the reading remains stuck at 22mA, technician experience suggests reballing the MediaTek CPU as the primary solution for this specific model. Forced Restart: For non-hardware issues, try holding the Power + Volume Up buttons for 15 seconds to rule out a software hang #RedmiNote9Dead #RedmiNote9Repair #DeadPhoneRepair #22milliamp #PhoneDeadSolution #MobileRepair #HardwareRepair #Troubleshooting #RedmiNote9 #CPUReballing (If applicable) #PMIC (If applicable) redmi note 9 restart problem solution redmi note 9 restart problem redmi note 9 auto restart problem solution redmi note 9 auto restart problem redmi note 9 automatic restart problem redmi note 9 restart redmi note 9 restart solution redmi note 9 redmi note 9 auto restart problem solution 1 minutes xiaomi redmi note 9 restart problem redmi note 9 restarting again and again redmi note 9 automatic switch off problem redmi 9 prime restart solution SGT Mobile Training Institute Bangalore Mobile Repairing Course in Hindi/ Kannada Mobile Chip Level Training Mobile IC Level Course Mobile Repair Academy Advanced Mobile Repair Best Mobile Repair Institute In India How to Repair Mobile Repairing Institute, Mobile Repairing Course A to Z, Kannada Basic Mobile Repairing Course in Hindi Best Mobile Repairing Training Centre In Kannada Mobile Repairing Course in Peenya 2nd stage, Bangalore Android Mobile Fixer Training Institute Bengaluru Mobile Repairing Training Services Complete Mobile Phone Repairing Course Mobile Repairing Complete Course In Kannada and Hindi Learn Android Mobile Repairing Course Samsung mobile Chip Reballing Course @SGTin‬ ‪@JYOTSNAMOBILECARE‬ ‪@cellphonesolution‬ ‪@MAXIMUMTECHNOLOGY‬ ‪@wefixitmobiletraininginstitute‬ ‪@Phoneway_Technical‬ ‪@BigMobileRepair‬ ‪@sandipsarkarofficial‬ ‪@MajidGoraya‬ ‪@YagneshmobileRepair‬ ‪008‬ ‪@CINOTechnology‬ ‪@android‬ ‪@rizwanmonitor1254‬ ‪@PhoneRepairGuru‬ ‪@5MINUTEREPAIR‬ ‪@1AAuto‬ ‪ @MobileRepairTrick‬ ‪@Mobileguruz‬ ‪@localmobileengineer‬ ‪@Tech‬ ‪@alitechnicalinstitute‬ ‪@TechnicalGuruji‬ ‪@TechBurner‬ ‪@rewatechnology2 Facebook : / profile.php Instagram : / profilecard YouTube : / @sgtin Course Details : - 1.
