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 :-(

It`s not your fault tear down is rather incomplete. It doesn`t have complete instructions as to deconstruction for repair.

3.2.4.7. Dolby surround
check
Adjustment procedure (1) Set to SURROUND: DOLBY <heck that the following waveforms are obtained. *Front: 4OOHz is superimposed on 5kHz. *Rear: R and L are the same signal and 400Hz is superimposed on 5kHz.
FRONT L REAR
Adjustment preparation (1) Receive the reverse cross-hatch pattern signal. (Crosshatch lines are black.) (2) Set CONTRAST to maximum BRIGHTNESS to center. (3) Lens focus should be completed. (4) Electrical focus should be coarse adjusted. (5) The digital convergence RAM should be cleared (uncorrected state). With the TV set off, press and hold the service switch located on the front panel (see page 1 l), and then press the power button. Use a small insulated tool to reach inside the control panel to press the switch. (6) Raster inclination should be completed. Adjustment procedure (1) Project only green color. Cover R & B lenses or short 2P mini connectors on CPT P.W.B.�s. (2) Adjust H-size to minimum. R649 fully counterclockwise. (3) Adjust green centering magnet (located on DY) to shift picture left to display edge of raster. (4) Adjust AFC (R367) so foldover of front porch occurs. Amount of foldover is l/2 to 2/3 of front porch (t?,).

3.3.DEFLECTION SYSTEM ADJUSTMENT 3.3.1. Raster inclination adjustment (Deflection
Adjustment preparation (1) Receive the reverse cross-hatch pattern signal. (Crosshatch lines are black.) (2) Set the video condition to factory reset. (3) Turn the shoot balance adjustment VR (R333) fully counterclockwise. Adjustment procedure Gradually turn the shoot balance adjustment VR (R333) clockwise and adjust so that the width of pre-shoot and over-shoot of the vertical line (black) shown in the circle pattern are balanced. (Visually adjust.)
Adjustment preparation (1) The set can face east or west. (2) Input the single cross test signal. (3) CONTRAST: MAX BRIGHTNESS: CENTER (4) The lens focus adjustment should have been completed. (5) The electric focus should have been coarse adjusted. (6) The digital convergence RAM should be cleared (uncorrected state). With the TV set off, press and hold the service switch located on the front panel (see page 1 l), and then press the power button. Use a small insulated tool to reach inside the control panel to press the switch. (7) Start adjustment 20 minutes or more after TV is turned on. Adjustment procedure (1) Apply covers to the R and B lenses and project only green light. (2) Turn the G deflection yoke and adjust the vertical raster inclination.
