THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR
;
Very Good! All the diagram are easy to read, and its complete.
;
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!
Trouble Shooting Guide, Standard
If the fault remains, send the unit on according to the local company directives. 2 - VDIG (3.2 V) is incorrect: Replace N701. If that does not help, send the unit on according to the local company directives. 3 - I2CDAT (3.2V) is incorrect: Measure the resistance of R619 (6.8 kohms). Check the soldering at D600:3. If both the resistance and the soldering are correct, replace D600. 5 - I2CCLK (3.2 V) is incorrect: Measure the resistance of R620 (6.8 kohms). Check the soldering at D600:4. If both the resistance and the soldering are correct, replace D600.
5.4
The display is black
Open the phone and check for liquid damage. Try again using a display you know is correct. If the fault remains, measure the resistance of R808 (33 kohms). If the resistance is very low, replace C824 and C826, otherwise replace R807 and R808. If the fault still remains, send the unit on according to the local company directives.
5.5
The background illumination to the display is missing or faintly glowing
Open the phone and check for liquid damage. Make sure that all LEDs (H651, H652, H653 and H654) are mounted and correctly soldered. Give the board power and start the board. If only a couple of the LEDs are faulty, replace them. If none of the LEDs are lit, measure the resistance on one of them. If the resistance is 0 ohm, there is a damaged foil in at least one of the LEDs. Remove the LEDs one by one in the following order: H654; H651, H653 and finally H652. Measure the resistance after each removal. When the resistance increases, the fault is found. If the resistances of the LEDs are too high, make sure that VBATT exist on them. If VBATT is missing, the phone is probably liquid damaged. If VBATT is correct, make sure R607 (1.0 kohm) and R609 (2.7 ohms) are mounted and correctly soldered. If none of the LEDs H651-H660 are lit, measure the voltage at R607, on the pin closest to D600 (0.55 V). Before measuring you have to press one of the keys to let the processor set LED3K high for approximately 10 seconds. If the voltage is missing, check the soldering at D600:69. If the soldering is correct, replace D600. If the fault still remains, send the unit on according to the local company directives.
