it sounds like you're diagnosing a power issue with an electronic device, possibly a mobile phone or other small electronic device. Here's a breakdown of what each term might imply:
1. *No VBAT SHORT*: The VBAT line is not shorted, meaning there is no direct short circuit across the battery terminals.
2. *No VPH SHORT*: The VPH line, which typically refers to the voltage power hub or some high power rail, also has no short circuit.
3. *No POWER ON*: The device is not powering on, despite no obvious shorts on the VBAT or VPH lines.
4. *Auto Consume Up to 3 Ampere*: Despite the device not powering on, it is still drawing up to 3A of current, which suggests that there may be a serious internal fault causing excessive power consumption.
Possible Causes:
- *Internal Component Failure*: There could be a component that is damaged or malfunctioning, causing high current draw without powering on the device.
- *Power Management IC (PMIC) Fault*: The PMIC might be defective, leading to abnormal power consumption without proper distribution.
- *Thermal Issues*: Overheating could cause the device to auto-shutdown while still drawing high current.
Suggested Actions:
1. *Check for Heat*: Identify any components that are heating up unusually. Use an infrared thermometer or a thermal camera.
2. *Inspect the PMIC*: Given the high current draw, focus on the power management IC to see if it's faulty or has any visible damage.
3. *Check All Power Rails*: Ensure that all other power lines (beyond VBAT and VPH) are functioning correctly, and there is no other short.
4. *Replace Suspicious Components*: If you find any components that are suspect, consider replacing them to see if the issue resolves.#bietthu

Ragul ஜீ, ஒரு புகைய போட்டா எல்லாம் தெரியுது 😊
ஒரு விசயம் தெரியாதவரை தான் அதற்கு மதிப்பு இருக்கும் தெரிந்துவிட்டால் அதனுடைய மதிப்பு குறைந்துவிடும்
