Providing the manual works fine, quickly and without any problems for an acceptable price. After printing the service manual it took me only a short time to repair my carradio from Clarion. Thank You! Greetings from Heiko

I was searching a way to modify the original phono-in entry (for connection of vynil disc player, with RIAA equalization) to a line-in entry (for connection of modern analog entries, eg. ipod, mp3player).
This service manual gave me the correct hints.
It contains very useful infos for repairing and modifing the hi-fi, such as disassembling instructions, block diagrams, schematic diagrams, PCB prints, replacement parts list.
Very good!

I must admit, I was very skeptical... $4.99 for a 74 page service manual. I've seen some very poorly scanned manuals on the Internet, but this one is VERY good quality! Even when zooming into 500%. Great Deal!

Very good detail, Quick service response. A useful service manual with all details. I recomend this service.
1. ELECTRICAL ADJUSTMENTS
1.1. Supply Voltage Adjustment Connect a digital voltmeter to the cathode of diode D611 at the AV1 mode of the TV and set the screen voltage to the minimum with the screen potentiometer. Adjust the main supply voltage (B+) with P601 potentiometer to the following value (after adjustment, readjust Screen voltage). 21� Pure Flat : 132 VDC 25� : 145 VDC 28� : 145 VDC (147 VDC for A66EAK071X11) 28� Pure Flat 16/9 : 140 VDC 28� Super Flat 16/9 : 140 VDC 29� Pure Flat : 125 VDC 29� Super Flat : 125 VDC 32� Pure Flat 16/9 : 140 VDC 32� Super Flat 16/9 : 131 VDC 33� : 158 VDC
2. SERVICE ADJUSTMENTS
You need the special service remote control to enter and exit the service menu of the TV (you can order it from the manufacturer). All buttons of the Service RC are same with the user remote control, only service menu In / Out is added to it (please see the picture below). Navigation Service In/Out : Enters to / exits from the Service Menu P+ / P: Moves upward / downward inside the menu V+ / V: Changes the values or options
2.1. AGC Adjustment � � � Apply an RF signal with amplitude 70±1 dBuV to the antenna input of TV with a pattern generator (switch sound carrier to Off and switch �Video Ext� to On). Switch on the Service Menu with the Service RC and find the AGC with P+ / P- buttons. Measure the 38.9 MHz signal on pin 11 (IF) of Tuner with an oscilloscope. Adjust �AGC� to get following values: PAL BG, PAL SECAM BG, PAL SECAM BG-DK, PAL I versions : 840 ± 20 mVpp PAL SECAM BG-LL version : 600 ± 20 mVpp PAL BG MONO, PAL SECAM BG MONO : 750 ± 20 mVpp PAL I MONO : 900 ± 20 mVpp Substract 5 from �AGC� value and change �TEST� to this value. Exit from the service menu with the Service RC.
