Thanks to this service manual I repaired my old camcorder! The manual perfectly explains how to disassemble the camcorder step by step.
This manual is very useful because it presents the technical specifications of the cd player, including the manufacturer of the reader, this helps if you need to replace it. It also displays the settings and layout of the circuit.
Manual was a good representation of service infomation for the EWV404. It worked well for my repair.
Great quality copy, right what I was looking for, all I need to fix my radio.
I BOUGHT A PAIR OF INFINITY VINTAGE SPEAKERS THAT REQUIRED TO BE REPAIRED AND THE ELECTRONIC TECHNICIAN ASKED ME FOR THE SERVICE MANUAL.
I TRIED TO GET IT AT THE MANUFACTURER'S SITE WITH NO SUCCESS, SO I STARTED TO LOOK FOR IT IN THE WEB FOR A LONG TIME, UNTIL I FOUND THE SERVICE MANUAL IN THIS EXCELLENT SITE "OWNER'S MANUAL.COM".
NOW I HAVE MY SPEAKERS WORKING AND ENJOYING THE MUSIC I LIKE.
THANKS TO "OWNER`S MANUAL.COM" I RECOMMEND THIS SITE TO EVERYONE.
Other service adjustments
Adjust 90â CRTs horizontal amplitude with coil LK 12. Adjust 110â SQ and FST - CRTâs with resistor RK66.
Note! Before other adjustments Ul voltage must be adjusted. If the set cannot be switched on with the number buttons, please see under âRC Modeâ (Service menu 2). Wait! Allow the TV set to be switched on for 10 minutes before any adjustment.
Select the service mode by pressing the Mute, OK (MI and TV buttons in sequence on the remote control unit. Use the blue button to call up the Service Menu 2, 3 (or Service Menu 1 again).

G2 and colour temperature
1. Set the UG2 adjustment (the lower adjustment at horizontal transformer) to its middle position. 2. Select the IDEAL picture setting and switch the set to AV programme number or other black screen picture. 3. Using the oscilloscope with 1OO:l probe determine the colour cathode with the highest black level measuring pulse at IC NHOl, pins 9, 12 and 15. 4. Adjust the highest measuring pulse to 150V (measured against ground).

Detune the IF signal to approx. 39 MHz (39,7 MHz, 34 MHz). Then the voltage must drop to approx. IV.
Sound of multistandard sets (standard BG, DK or standard I)
Make the standard adjustment as follows: 1. RCF remote control unit: Press the PROG button. RCN remote control unit: Press the blue MENU button twice. 2. Select the menu line Tuning, Manual tuning. 3. Select STANDARD BG, DK or I with cursor buttons 4 and ). 4. Store the setting by pressing the OK (M) button. 5. Return to normal TV viewing by pressing the TV button.
Adjustment Ul voltage
1. 2. 3. 4. 5. Set the contrast and brightness to minimum. Connect test point XFOI (chassis board) to ground. Go to service menu 1 (see service mode). Use cursor button A or v to select Ul-adjustment. Adjust with cursor button 4 or) IlOV f IV 14â (Philips/Samtel ) and 20â (Videocolor) 135V i IV 21â (Philips) 150V + IV 25â and 28â (Videocolor) 6.
