Measure the voltage on pin 2 of V621 (3.7V).
If the voltage is incorrect the foil is damaged. Send the unit on according to the local
company directives.
Measure the voltage on pin 3 of V623 (3.7V).
If the voltage is incorrect, measure the resistance of R683 (100 kohms). Replace it if it is
incorrect.
If the voltage is correct, replace V621 and V623. Make sure that R627, R628 and C681 are
mounted and correctly soldered. Measure the resistance of R682 (1 kohm).
If the resistance is incorrect, replace R682.
If the fault remains, send the unit on according to the local company directives.
