available for me the service manual is in order!
thanks
 ;
This is exactly the thing you need to service this box. The manual is complete and the quality of the scan is good. I recommend this!
;
The delivery of this manual was very fast, less than 8 hours. The manual is very clear and concise, and helped a great deal in the repair and final setup of the Hitachi HMA-G2 Amplifier.

Great service. The manual was exactly what I was looking for: schematic + layout. I managed to fix the player. Highly recommended!

At $5,00 certainly good bang for your buck. Includes electric schematics as well as exploded parts view + parts list for reordering. Unfortunately no details on the PCB contents or working, but then again, this is not overly complex. Best bonus: this manual does contain the heavily searched for LED error codes as well as descriptions for test operation. Haven't gotten around to fixing the machine yet, one thing the manual won't do for you is getting it out of the kitchen assembly :-(
KD-SH99R
Flow until reading TOC of CD/CD-R/CD-RW
FEED RETURN Becomes DRVMUTE=H and the output of the IC604 driver becomes possible. Picking up is moved to surroundings on the inside until becoming REST SW=L. Afterward, moves in the direction of outer again and stops in the place in which became REST SW=H. FOCUS OFFSET, TRACKING OFFSET, and RF OFFSET are done, and OFFSET of RF AMP in IC603 is corrected.
2.8Vp-p
OFFSET SELF ADJUSTMENT LASER ON Pre SP KICK LENS UP FOCUS ON
2.0Vp-p
400ms turns the spindle motor before the focus search starts. Lens UP of the pick is done. At this time, S character curve becomes about 2.0Vp-p by CTS-1000. The down of the lens and FOCUS ONing are made. Changes into CD-RW MODE, and serches for FOCUS in case of no FOCUS ON even if FOCUS search(UP DOWN) is done three times. The spindle motor is rotated up to the number of necessary rotations. In the state of tracking OFF, do the self adjustment of wavy OFFSET of TE2 to 0. It takes time to adjust the one with a large gap of the traking balance of picking up. At this time, the racking error becomes about 2.8Vp-p by CTS-1000. In the state of traking OFF, do the self adjustment of the RF level of RF(TP601) to 1.0-1.2Vp-p. After adjusts,traking ON is done. Do th eself adjustment of the gain intersection of the focus servo to 1.2kHz (300ms). Do the self adjustment of the gain intersection of the focus servo to 1.2kHz. (300ms). Time expands in DISC that the number of total tracks with CD-TEXT is a lot of. It is a head of 1Tr., and the reproduction begins.
