Marantz Receiver: geen geluid uit de receiver!

Sun, 26 Jan 2025 08:24:48 -0700

ik heb een marantz NR1501

sinds een tijdje krijgt het apparaat steeds meer kuren met opstarten. knisperend geluid bij het opstarten (speakers zijn niet kapot/opgeblazen) het knisperen lijkt op stroom kortsluitingen en is alleen bij het opstarten en daarna vloeit het langzaam weg en heb je normal geluid. nu heb ik bij het opstarten helemaal geen geluid. bij alle outputs heb ik nu geen geluid meer. resetten heb ik ook al uitgevoerd. weten jullie misschien wat er aan de hand is?

Online Translation.

No sound from the receiver !

I have a Marantz NR1501

Since a while the device gets more and more courses starting up. crackling sound at startup ( speakers are not broken / inflated ) the rustle similar to current short circuits and only at startup and then flows slowly and have normal sound. now I have no sound at startup. all outputs I have no sound anymore. Resetting I already performed. you may know what is going on ?

Home Audio Receiver: Tweedehandse Akai AA-V12DPL tunerfunctie werkt niet + rear uitgangen

Thu, 14 Jan 2021 16:34:55 -0700

Hi,

Ik ben nieuw in de hifi wereld. Ik heb onlangs een tweedehands amplifier gekocht. Bij het testen leek alles te werken, toen ik thuis aankwam, merkte ik dat de tuner het niet deed. Het geeft een statisch geluid en maakt geen contact met kanalen, lijkt het. Er zit gewoon een FM kabel in, die het wel deed op mijn oude tuner. Daarnaast probeerde ik met mijn speakers op het gedeelte “surround sound speakers” aan te sluiten. “Center” deed het wel, “rear” uitgangen deden het niet. Wie o wie kan mij hierbij helpen? Alvast bedankt :)

Marantz Receiver: Audio knob causes audio loss

Fri, 12 Jun 2026 01:58:39 -0700

I have been hammering away at this Marantz receiver over the past couple of days. I had it working flawlessly. Then I turned it off and back on. Now a problem has arisen. If I turn it all the way up and turn it on, the audio is extremely quiet and if I turn the volume knob, the audio just dies completely. Any suggestions?

Marantz Receiver: Marantz SR6013 Amplifier Circuit Failed

Sat, 23 May 2026 08:32:21 -0700

I’ve removed all connections, plugged into a different outlet, reset to factory defaults, re-initialized it, and I’m still going directly into the power indicator flashes red every 0.5 seconds. So I’m pretty sure it’s the Amp Circuit in some way…

It’s out of warranty (90 day refurbished warranty was up in June 2019)

Hoping to fix it myself as I paid $2k for this thing and I’m really !#^&@@ off right now that this has happened.

Does anyone have any advice on what to look for inside the receiver? I’m hoping it’s just a blown capacitor I can replace but I’m not sure where to look first and what to see if there is something noticable.

Thank you for any help or advice,

Solid State Logic SSL 2: Passive Speaker Output Fried Interface

Fri, 22 May 2026 03:33:58 -0700

Hello everyone!

So today I failed to use my brain - the following happened:

I tried to connect my vintage sony Hi-Fi-System to my SSL 2+ interface. Since it only has the red and black connectors for passive speakers as an output, I figured I'd simply make a makeshift cable and connect it to my interface. In the two inputs of my interface I plugged a double mono-jack to cinch cable. At the end of the cinch cable I wrapped around a wire so I could plug it into the output of the Hi-Fi player. It worked for 10 seconds, then a pop came through the speakers as if I had just unplugged them and the interface stopped working. For the most part at least.

What works:

-Power LED is on

-4k Buttons light up

-Gain LEDs work (on startup, shows gain when pushing the 4k button, blinks when dis-/enabling +48V)

-miscellanious buttons (I think)

-USB connection (is recognized by the PC, able to reset and update firmware)

What doesn't work (anymore sadly):

-input (not via mic, not via line)

-output (not via speakers, not via headphones)

What's weird:

-4k buttons glow very bright red when disabled (should be off), when enabled they glow slightly dimmer red

4k button engaged

4k button disengaged

back of the board

Question:

Since part of the electronics seem to still be working I'm hopeful I could try and repair it. However, I lack the knowledge to identify which part might be faulty. Where do I start looking? How do I do it? Is it even doable (maybe too small of a part to replace by hand?)

A few quick inspections don't seem to reveal any obvious faults like undone soldering spots or popped capacitors.

I have a Marantz NR 1504. It turns on well, but no sound in the output.

I am a basic analogue geek. But this one is digital and i cannot trace faults.

Do you have a repair manual for this marantz receiver?

Home Audio Receiver: Marantz SR 92 Receiver

Wed, 18 Feb 2026 22:37:48 -0700

I have crackle sound on my right channel on my Marantz SR 92 receiver(volume "zero"). I have sent it out 3 times for repair, none are able to resolve this problem. Some website indicated that to resolve this, I need 4 transistors, a Mosfet and a resistor. If I can get the circuit diagram on the component location and component types (no.), I may be able to do it myself. SOS. Thanks.

Pioneer VSX-421-K: VSX-421 problem when powering from standby-mode

Sun, 18 Jan 2026 04:12:03 -0700

Hi, I have this reciever, I bought it faulty and replacing relays fixed all the problems but this one:
Reciever works normally until I turn it off/ put it in standby-mode and let it sit for some time. After that when I power it up it turns on but goes off in like 2 seconds. I have to reset it 1-3 times with enter+standby-button and after that it works again normally until I turn it off and let it sit for some time in standby-mode. I have not founded a schematic for this so it's difficult to troubleshoot. Inside it all looks really clean and no bulging capacitors or anything. When I press preset+standby, it gives only these: DC: 039, temp1: 00, temp2: 00, Over: 255. I have no idea what these mean :D How would you proceed to troubleshoot and can anyone tell me where to find the schematic for this model? Thanks!

Home Audio Receiver: Harman Kardon AVR151/230 amber light blinking

Sun, 11 Jan 2026 14:48:49 -0700

Service center technician said the main board has to be replaced.

But they are not wiling to repair the main board in component level. Guess they prety much saves time but replacing the whole board rather than spend time locating the faulty component.

Can anyone give me a starting point to start diagnose the main board by myself. I’m a hobbyist and have slight knowledge of electronics.

So you can be technical with your answers.

Help would be highly appreciated!

Pioneer VSX-821-K: No Power - not surge related

Tue, 30 Dec 2025 18:10:29 -0700

Used this receiver one day, the next it was dead. There was no power outage or surge. There is no display and not responding to the remote or switch. Checked all the power components and they appear to be okay. Getting power to the unit, but not going through the transformer on the power supply board. Relay is not clicking, not getting the signal to turn on. I tried to trace this problem, but I do not have the service manual for this unit and did not see it anywhere on the internet. Checked your site and you do not have it, but thought maybe you can help look for the problems. Any suggestions on what to check next?
