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!

SELF-DIAGNOSTIC FUNCTION
Self Diagnosis
Supported model
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/STEREO LED will automatically begin to �ash. The number of times the LED �ashes translates to a probable source of the problem. A de�nition of the STANDBY/STEREO LED �ash indicators is listed in the instruction manual for the user�s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur. Diagnostic Test Indicators When an error occurs, the STANDBY/STEREO LED will �ash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the �rst of the problem areas. Results for all of the following diagnostic items are displayed on screen. If the screen displays a �0�, and error has occurred.

� Power cord is not plugged in. � Fuse is burned out (F5501)
Detected Symptoms
� Power does not come on. � No power is supplied to the TV. � AC power supply is faulty. � Power does not come on. � Load on power line is shorted.
+B overcurrent (OCP) (see Note 1)
2 times
2:0 or 2:1
� H.OUT (Q5030) is shorted. (D Board) � +B PWM (Q5003) is shorted (D Board) � IC9001, IC9002, IC9003 is shorted (C Board) � IC6505 is faulty. (D Board) � ± 15V is not supplied. (D Board) � IC5004 is faulty. (D Board)
Low B overvoltage (OVP) Vertical de�ection stopped
3 times 4 times
3:0 or 3:1 4:0 or 4:1
� Has entered standby mode. � Has entered standby state after horizontal raster. � Vertical de�ection pulse is stopped. � Power line is shorted or power supply is stopped. � No raster is generated. � CRT cathode current detection reference pulse output is small.
White balance failure (not balanced)
5 times
5:0 or 5:1
� Video OUT (IC9001-IC9003) is faulty. (C Board) � CRT drive (IC201) is faulty. (A Board) � G2 is improperly adjusted. (see Note 2) � +5 line is overloaded. (A, B Boards) � +5 line is shorted. (A, B Boards) � IC6007 is faulty. (A Board)
LOW B OCP/OVP (overcurrent/overvoltage) (see Note 3) Horizontal De�ection stopped
6 times
6:0 or 6:1
� No picture
7 times
7:0 or 7:1
� No picture
Note 1: If a +B overcurrent is detected, stoppage of the vertical de�ection is detected simultaneously. The symptom that is diagnosed �rst by the microcontroller is displayed on screen. Note 2: Refer to Screen (G2) Adjustment in Section 3-4 of this manual. Note 3: If STANDBY/STEREO LED �ashes six (6) times, unplug the unit and wait 10 seconds before performing the adjustment
Display of Standby/Timer LED Flash Count
Diagnostic items +B overcurrent +B/Low B overvoltage Vert. deflection stopped White balance failure Low B error Horiz. deflection stopped Flash count 2 times 3 times 4 times 5 times 6 times 7 times Standby/Timer LED Lamp ON 0.3 sec. Lamp OFF 0.3 sec. Lamp OFF 3 sec.
* One �ash count is not used for selfdiagnostic.
Stopping the Standby/Timer LED Flash Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER LAMP from �ashing. Self-Diagnostic Screen Display For errors with symptoms such as �power sometimes shuts off� or �screen sometimes goes out� that cannot be con�rmed, it is possible to bring up past occurrences of failure on the screen for con�rmation.
