Hello

This isn't a solution I'm afraid but we have also suddenly lost all power for the same Hitachi model (have checked the fuses too) and were wondering if you ever found a solution to your problem?

Check the power supply rails on the secondary side of the power

transformer.


• Check the presence of AC outputs on the transformer secondary

windings

• Check the diodes and capacitor circuit


• Check the regulator circuits

How can i check what is wrong with my amp in order to get it to turn on


If your amplifier is not turning on, it is important to have an idea of the cirrcuit within to probe into the circuits.First of all look for the power spply lines, check the voltage to the amplifier with a multimeter in the volt mode. Now look into the circuit where the power goes in , check for any signs of fused resistors, fuses within or even burned tacks in the PCB. If voltage comes into all the circuits and to the output drivers, be sure to check for the input siganl and the preamplifier section. The signal from the head unit must be checked or else you can use a test signal- audio- to confirm. With this you will have an idea of the fault section. Get help if not familiar with the electronics section , tampering will be irrepairable. Good day

Nad c350 no power at all


Solution if all fuses checked out OK and +/-40V are present on main PCB DC connector from power supply:
Check for +37V and -37V on small sub-power supply PCB - mounted vertically on the main power supply PCB. (next to ribbon cable connector is a layout with voltages.) If the +/-37V are missing check (replace) C501 (0.1uF) on the small power supply PCB for leakage, but also check (replace) R401 (2R2) and R402 (2R2) on the main power supply PCB. Both resistors are fuse-resistors and will have gone open circuit when C501 has gone leaky.

Nad amp failure


Check fuses mounted near transformer . If blown check output transistor. Also check transistor transistors on small heat sink . they will cause fuse to blow.
