It's exactly a complete and very useful manual with all details what I needed. Thank you!I will come back whenever I need your manuals or schematics.

I searched EVERYWHERE looking for the manual/s on this "extinct" amp. Owner-Manuals.com made it available and for nearly nothing. Thanx to them, I can decipher the unknown cables and sort them out. Thanx, Owner-Manuals.com!!

Yes thank you i got the file i was after. There was a slight problem in my communication but it all worked out well.
A job well done.

Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

I've been in the electronic business for a long time. I used to buy Sam's Photofact for my needs which intailed having to go to the store and paying about $20 for a package of 3 different units so I was forced to buy more than I needed just to get one.
Owner manual is just at your keyboard and the information is almost instantansouly and the cost is very reasonable. Easy to print out if needed or simply read off of the screen. The larger the screen the better for obvious reasons.

Check points for each error
(1) Spindle start error 1.Defective spindle motor *Are there several ohms resistance between each pin of CN201 "5-6","6-7","5-7"? (The power supply is turned off and measured.) *Is the sign wave of about 100mVp-p in the voltage had from each terminal? [ CN201"9"(H1-),"10"(H1+),"11"(H2-),"12"(H2+),"13"(H3-),"14"(H3+) ] 2.Defective spindle motor driver (IC251) *Has motor drive voltage of a sine wave or a rectangular wave gone out to each terminal(SM1~3) of CN201"5,6,7" and IC251"2,4,7"? *Is FG pulse output from the terminal of IC251"24"(FG) according to the rotation of the motor? *Is it "L(about 0.9V)" while terminal of IC251"15"(VH) is rotating the motor? 3.Has the control signal come from servo IC or the microcomputer? *Is it "L" while the terminal of IC251"18"(SBRK) is operating? Is it "H" while the terminal of IC251"23"(/SPMUTE) is operating? *Is the control signal input to the terminal of IC251"22"(EC)? (changes from VHALF voltage while the motor is working.) *Is the VHALF voltage input to the terminal of IC251"21"(ECR)? 4.Is the FG signal input to the servo IC? *Is FG pulse input to the terminal of IC301"69"(FG) according to the rotation of the motor?
(2) Disc Detection, Distinction error (no disc, no RFENV) * Laser is defective. * Front End Processor is defective (IC101). * APC circuit is defective. --- Q101,Q102. * Pattern is defective. --- Lines for CN101 - All patterns which relate to pick-up and patterns between IC101 * IC101 --- For signal from IC101 to IC301, is signal output from IC101 "20" (ASOUT) and IC101 "41"(RFENV) and IC101 "22" (FEOUT)?
