I’ve just moved flat from the U.K. to Spain and in the move my Denon receiver looks like it took a bit of a whack, the front panel has a dent etc. I went to turn it on and it boots before going onto the blinking red light issue after a couple of seconds. I’ve downloaded the repair manual and gone through the debug process and when I disconnect the speaker board the amp stays on and it displays that the previous fault was an ASO protection which apparently means there is a short in the signal path, such as speaker wires touching but it happens even when no speakers are connected. Does anyone have experience with these in the past? The fuses are fine. The PSU is producing the correct voltages when the rest of the pcbs are disconnected so I don’t think it’s the PSU issue some other owners have had. I’ve tested the transistors and resistors on the amp board and I don’t think any are off, the parallel pairs are measuring between 0.2 and 0.3 for parrallel .47Rs and the transistors are doing 0.45-0.65V between the legs. Some of the resistors do have some discolouration though that they might have got a bit hot at some point. My feeling is it is a loose connection somewhere but I can’t see it and I’m not too keen on going further into the big hdmi/power amp pcb stack as I don’t think I’ll get it back together. Is it worth me replacing the resistors in case that is the issue? Any other tips before start removing components?

I need a recommendation for repairing my Yamaha KX-580. The right channel has dropped out to about 10% of normal. The VU meters show a normal signal for both channels. The head phones are dead on the right, but that's a preexisting issue. It's my number 2 deck in my main system so it's not a rush job. Still I use it enough I really need it fixed. I live in SW Missouri and there is no one around here that I am aware of. I've been on net but I would still like some direction from.the community. And why does there need to be flair. It reminds me of Office Space.

Hello all, I am trying to run one MC58 in bridge mode from a CR16 and cannot get the bridged speakers to play. I would like help to confirm the correct wiring for this combination.

Equipment:
CR16 multizone controller
MC58, all four pairs set to Bridge, intended as four bridged channels
Zone 1: MC275, not using the MC58
Zones 2 and 3: two B&W AM-1s each, so each zone needs two bridged MC58 channels
Zone 4: no speakers

Sources: MP100 on AUX, MB50 on CD2
Trigger chain currently: CR16 to MP100 to MC58 to MC275, using 1/8-inch power control
7-pin DIN from the CR16 multi-channel DIN, the jack beside the DB25, to the MC58 MULTI-ROOM jack
DB25 is not connected

Audio is on the odd RCA inputs: 1, 3, 5, and 7
MC58 rear switch is Remote, front power switch is on.

What the MC58 actually does:
CR16 Zone 2 on lights only the 3/4 pair
CR16 Zone 3 on lights only the 5/6 pair
CR16 Zone 4 on lights the 7/8 pair, even though Zone 4 has no audio output connected
CR16 Zone 1 on does not light the 1/2 pair. Zone 1 audio goes to the MC275 only
With the DIN unplugged, the logo comes on at startup but no pair lamps light, including with the 1/8-inch trigger connected
Result: a bridged stereo zone needs two powered pairs, but each CR16 zone enables only one pair, and 1/2 never enables. The bridged speakers have no sound.

Any thoughts are appreciated as I can’t get this to work. Incidentally, all the equipment is in a front load only audio rack so it’s quite difficult to remove and readjust..

These PW-2522BM woofers have stiff surrounds, thus very little movement. I've been advised to apply some brake fluid. Is this wise?

Advice appreciated

I have an RCA RS2534 5-disc changer stereo that is not reading discs. I’ve cleaned the lens and lubricated the rails, but still nothing. This is a 25-year-old stereo, so I’m not sure what replacement I can get, if any.

hello i don't know if this is the correct subreddit but i have a question can this adapter works with this radio is a sony hcd bx20i

Hey! I’ve got to replace 1 (!) knob on an old Yamaha mixer, but am struggling to find what the correct name for the type of knob required is. Doesn’t bother me if the replacement doesn’t look similar, it’s purely so the control can function. Any pointers appreciated, I think it’s a D shaft but I’m not having any luck with what to search for the type of design with the two tier style.

How do I access these speaker panels. I see a bunch of screws but we can only get to half of them because of the drop down component compartment on the right side. My mom wants to change the speakers and fix the fabric but we cant tell how they are attached.

My girlfriend has a single Pioneer DJ VM-50 that she runs off her DDJ-REV7. It suddenly stopped producing any sound at all.

The power LED still behaves normally:
It goes red when it drops into auto-standby
It switches back to white when the REV7 wakes up or a track plays.

So it seems to detect the signal and power on, but nothing comes out of either driver.
What we've ruled out:

No hiss at all, even with the volume knob maxed and an ear right against both the woofer and tweeter

The REV7 works fine through headphones

Tried different REV7 outputs, with Master and Booth levels up

Swapped cable ends and wiggled the connections at both ends. No crackle, no sound.
Checked the volume and the settings on the back of the speaker

A shop quoted $300 to fix it, which is close to the cost of a new one.

Honestly, we're pretty new to this and don't really know how to go about diagnosing it. We're both pretty handy with this kind of thing though, so we'd love to try fixing it ourselves if it's realistic. Is this something we could DIY? Any pointers on where to start would be hugely appreciated.

Thanks in advance!

I've had my AXC35 for a number of years, and I love it. Recently, however, the drawer has developed an issue. When a CD is inserted, the unit makes a grinding sound and refuses to recognize the disc. Opening the drawer and then closing it again usually gets the player to recognize the disc and they always play without an issue. Is there a way I can eliminate this problem?

Hi all. Managed to grab a Beosound 3200 and Beolab 2400 set out of a skip the other day. Didn't really know much about it when I picked it up but seems after doing some research I've got pretty bloody lucky.

Unfortunately it doesn't fully work. The Speakers power on and the beosound powers on but not together. Seems like an issue with the connection between them? Also the front panel seems to get a bit stuck when opening and closing. Is this just a case of cleaning it out?

Hope to get it working and tested soon :D

There is a weird metallic artifact/undertone from the FM section of this Onkyo receiver. Sounds like some kind of bad digital compression. More apparent with music with distortion or reverb, or lots of audience noise. Hear it on all stations, don’t hear it on my car radio with same signal. Not using any of the DSP modes. Is this just how this receiver sounds?
