It was a great experience,instead of purchasing a new Stereo Amplifier ,in just minutes i repaired my old one and that was thaks to the manual I have purchased from you.
Thanks again.

Das ging ja sehr unkompliziert hat bestens geklappt und die Quallität ist auch noch gut.
Vielen Dank dafür.

Everything okay, thanks a lot. It was a pleasure for me to make a deal with you.
;
A deal without problems, very fast and the manual is a good quality. Sorry for the my english.

* 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).
