Samsung P1000 Galaxy Tab USB Not Charging Solution

This is the hardware repair solution for Samsung Galaxy Tab P1000 if it doesn't charge. This may only works if the device still turns On and the battery is not fully drained or already weak or damaged. A fully discharge battery will unable to charge up, so ensure that the battery is still in working condition before applying this solution. You may also consider that the wall or dock connector charger is also working fine.

So, lets take a look how the troubleshooting flows on the Samsung Galaxy Tab Not Charging problem:

1. On the 30 pin dock connector the input charge voltage is on pin #7 and #8. You can check and read it using a multimeter while the wall or USB charger is being inserted. If the voltage is missing or no readings the possible faulty is the charger itself but if the voltage is okay proceed to step 2.

2. On the charger voltage detector chip Pin #6 and #7 check and read the VBUS output voltage. If the voltage is missing, check the chip for possible crack, open etc., rework or replace if necessary. If the voltage is okay proceed to step 3.

3. Check the VBAT(battery voltage) on the capcitor near the charger switching IC. If the voltage is missing or no readings the possible faulty is the charger switching IC. If the voltage is okay, proceed step 4.

4. Check the VUSB output voltage on the analog multiplexer IC which is around 5V up on the capacitor. If the voltage is missing, check the chip for possible damaged and etc. Replace if necessary.
