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.
Thanks

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.

Very quick response. Very good and accurate print quality of the scanned document.
(5) Lighting in green, and then in red (Alarm of power voltage error) Unlike [lighting in red] in the STANDBY mode, [lighting in green] continues for about 30 seconds without any output of images and audio signals. Since then, the mode turns into [lighting in red]. (Caution) How to reset the alarming condition The alarming condition can be reset when an OFF�ON setting is repeated twice for the main power supply in the state that the LED is lit in red. The interval between the first and second settings is not particularly specified.
Lighting in red
Make an OFF � ON setting twice for the main power supply in order to reset the alarming condition. Is the LED lit in red after it has been lit in green for about 30 seconds? YES When the main power supply is turned on in the state that the AD, PD, and PH connectors are disconnected, are there the Vs (170Vdc) and Vd (60Vdc) outputs at Pins 6-7to Pins 9-0 of the PD connector and a 5Vdc output at Pins 1-2 of the PH connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? At that time, however, no images are generated. NO When the main power supply is turned on in the state that the PA and PV connectors are disconnected from one after another, is there a 12Vdc output at Pins 1-3 of the PA connector or the 12Vdc and 6Vdc outputs at Pins 1 and 3-4 of the PV connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? NO Is there an output of 3.3Vdc available at Pins 1~3 and 2.5Vdc at Pins 7~9 in the state that the PA and PV connectors are returned to the former state, the main power is turned ON, and the PN connector is disconnected? In this case, however, this check must be finished in 30 seconds. Otherwise, there will be power tripping on account of an alarm. NO
Normal
Refer to P7-1 "HOW TO DIAGNOSE THE PDP MODULE". YES The PDP is fault. (Caution) The voltage values of Vd and Vs can differ according to the PDP. The method of checking these voltage values is obtainable from [2. Adjustment of the power unit] in the method of adjustment.
YES
The MAIN PWB or the AUDIO PWB is fault.
NO
The Power unit or the PN connector is fault.
YES The MAIN PWB is fault.
