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.
Troubleshooting
5-3-10 (N) Check of instantaneous over-current protection of IPM circuit.
Inverter instantaneous over-current protection mode is the mode to be actuated in order to prevent the damage of elements from the peak current of IPM circuit elements. In case that the inverter circuit instantaneous over-current protection mode actuates.
(condition of installation)
�The ventilation is not good because the outdoor unit is installed wrong (the ambient temperature is higher than 50 (°C) ) -> Reinstall the outdoor unit so that the good ventilation can be made. �In case that the operation is made with the cover bent of the outdoor unit. -> Take out the cover. �If two outdoor units are operating face to face, (the bad ventilation is made) -> Reinstall the outdoor unit for the good ventilation. �The air circulation is bad due to the attachment of falling leaves. -> Take away the leaves for the good ventilation. �If the Refrigerant is overcharged. -> Check the amount of Refrigerant.
(Unit defect)
�If the comp is locked. -> Replace the comp. �If the comp is operating without the revolution of fan motor. -> Check the fan motor connector and replace the fan motor. �In case the parts of the control board is damaged. -> Replace simultaneously the inverter control board and the IPM board.
5-3-11 (O) Check of the comp discharge gas temperature and OLP temperature abnormal rise.
If the comp discharge gas temperature and OLP temperature rises higher than a certain level, it protects the circuit. If the comp discharge gas temperature and OLP temperature rises abnormally,
(Condition of installation)
