Harman kardon avr 146 no front led display. but clicks on from orange light to blue. is there a fuse for display screen ? fuse at AC in is OK.
Hello, there is no fuse for the screen, there is a power supply circuit that makes it work and that if it is wrong the screen does not work
The rest of the team works well? Can you hear something?
if not, you do not have a display problem, you have a bigger problem
If you have knowledge to review it, I will attach the service manual, but go to a specialized technical service
Hola, no hay fusible para la pantalla, hay un circuito de fuente de alimentaci?n que lo hace funcionar y que si esta mal la pantalla no funciona
El resto del equipo funciona bien?, puedes escuchar algo?
si no, no tienes un problema de display, tienes un problema mayor
si tienes conocimientos como para revisarlo, te adjunto el service manual, sino dir?gete a un servicio t?cnico especializado
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.
