VOLTAGE PROTECTION CHECK DSP
AMPLIFIER HARMAN KARDON:
Code: <check input> means: fuses resistors back of the transformer. They should have .4 ohm low ohm. Often they go on kilo ohms or mega ohms, means they are open. Change them. That's it. Code: <Check DSP> means something on logical board or flat strap connectors defect. Also check voltage on output collector and also check -15 volts and +15 volts on multiplug up on the middle right of the amp on the logical board. Check all voltage preamp on connector cn21 and cn24 on right of the logical board up middle right of the amplifier. I'm a certified Harman kardon technician. If you have other questions, just ask me. Good luck all. Serge.
AVR amber light will not return to blue after
There is an internal reset switch mounted on the transformer board. Open the unit, look at the boards attached to the transformer, the pushbutton is facing up. Measure the voltage on the 2 pins of the switch. If it is a logic low, the switch is partially shorted. Replace the switch or just cut the jumper wire just below thw switch. When this switch fails, it constantly resets the receiver and stops it from powering up. It does not fix a protection mode problem.
I have a HK 595 sub. with no sattelite cables.
you need the the satellite speakers hooked up in order for the sub to work. its not a standalone sub the volume control knob on the satellite speaker is what powers on the sub. i have extra speakers i wish i could give you cuz my sub just blew out.
HK 3480 sound suddenly cuts out
your fuses are blown by possible crossing speaker wire - and +
together. I did this and kept turning it on but I ended up frying the
unit. Check your wires and make sure that they are seperated properly.
If problem continues then unscrew the shell and replace 1 or all 3
fuses (depending on what was blown) with GMA 8 amp fuses. good luck.
My Harman Kardon AVR 220 reciever's front-right
if front left is working it is possible u have a dry solder on ur right channel line. try resoldering or if u want to know exactly where dry solder is, shake gently every right channel components and connections. if resoldering does not work it is possible u have a faulty ouput amp for ur right channel. if ur not sure about this i suggest u get it checked by a qualified tech.
