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 Harman kardon 1700Avr that is stuck in protect mode, Is there anyway to bypass or reset it? Thanks....

It's in the protect mode because of a component failure inside. It needs to be repaired to get out of the protect mode.

Why Harman Kardon HK 3490 goes into Voltage Input protect mode

Harman Kardon HK 3490 balance problem.

There is a download for the unit service manual attached to this. I repair this type of equipment and unless you know how to read this and have special equipment and knowledge, this is not something that you should attempt. Good luck.

Why is my digital signal not working on my harmon pardon 3490 receiver? it always returns to the analog signal

You can set it manually. Here is how: "To select whether the source will use its analog audio input or one of the digital audio inputs, press and hold the front-panel Source Selector and simultaneously tap the front-panel T-Mon Button repeatedly until the desired input appears in the Message Display. Audio input selection requires use of the front-panel controls and cannot be selected using the remote control."

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.
