I888, Standard Electrical Repairs
After every repair of the charging function, you have to verify the function using the
method mentioned in section 6.1.1.
If the fault still remains, send the phone to the next repair level.
6.4 The phone starts, but doesn´t charge, even
though it shows charging.
Open the phone and check for liquid damages. Make sure the system connector pads
are not burned or oxidized, especially on GND pin 10 (Fig 6.1). Measure the resist-
ance between DCIO and VBATT (390 Ohm, Fig 6.1). If it is too high, measure the
resistance of R421 (0.1 Ohm, class B, Fig 6.2). Measure the resistance of R411 (390
Ohm, class A, Fig 6.2). If R421 and R411 are correct and the resistance between
DCIO and VBATT is still too high, is there a foil damage and the phone has to be
discarded.
After every repair of the charging function, you have to verify the function using the
method mentioned in section 6.1.1.
If the fault still remains, send the phone to the next repair level.
