I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks

I believe this is the only place they have them in a very nice scan, Excellent guide: very clear, enabling us to print readable diagram overall it is great to have this manual available for purchase. This is a complete service manual no pages are missing. Thanks

A complete and well done copy of the manual, at a not expansive price!
The delivery of the manual is very fast.
Thank you for all

* Measure the resistance from X602 pad 5 to ground (>100 kohms). * If it�s too low, make sure there�s no dirt or oxide between the components in the marked area (�g. 4.5). Clean thoroughly and measure again.
Fig. 4.5 * If the resistance still is too low, remove R601 (class A, �g. 4.4). * If the resistance increased, replace D600 (class B, �g. 4.2) and mount a new R601. * If the resistance didn�t increase when removing R601 or it didn�t help by replacing D600, send the phone to the next level.
* Measure the resistance from X602 pad 3 to ground (>100 kohms). * If it�s too low, make sure there�s no dirt or oxide between the components in the marked area (�g. 4.5). Clean thoroughly and measure again. * If the resistance still is too low, remove R605 (class A, �g. 4.4) and measure again. * If the resistance increased, replace D600 (class B, �g. 4.2) and mount a new R605. * If the resistance didn�t increase when removing R605 or it didn�t help by replacing D600, send the phone to the next level.
If all the above measured resistances are correct, but some of the voltages at R601 or R605 are low it�s either caused by a slight short circuit due to dirt at the marked area in fig. 4.5, broken F603 or broken F604.
� If the voltages at R601 and R605 are correct, connect a handsfree to the system connector. � Measure the voltages at both sides of R601 (~0V, �g. 4.4) and at D600 pin 70 (~0V, �g. 4.2).
