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.

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.
1.
2. 3.
4.
Check the area of your repair for unsoldered or poorly-sol deredconnections. Check the entire board surface for solder splashes and bridges. Check the interboard wiring to ensure that no wires are �pinched� or contact high-wattage resistors. Look for unauthorized replacement parts, particularlyt ransis tors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.
5. 6.
Check the B+ voltage to see it is at the values specified. Flexible Circuit Board Repairing � Keep the temperature of the soldering iron around 270°C during repairing. � Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). � Be careful not to apply force on the conductor when soldering
