Cambridge CXA60 Amp Turns off Straight Away


Recommended Posts

Hi All. I'm having some isues with my Cambridge Audio CXA60 Amp (I think). I've had it since Jan this year and in general it has operated trouble free. However within the last month it has occasionally been turning off within about 5 seconds of turning it on. After pressing the power button it will appear to turn on, however before doing its final "click" it just turns off again. It seems to eventually come good and stay on after repeated attempts to turn it on.

 

As a side note. It has always needed a couple of presses of the power button on the remote to seemingly get a response from the unit to turn it either on or off.

 

Does any of this behaviour ring a bell for any other owners? I've tried ensuring that the power cable is plugged in fully when it has trouble turning on. Doesn't seem to help. ta

Replying to myself here. I noticed last night that pretty much all of the buttons had stopped responding nicely. Some would take 2, 3 or more presses to respond. Sometimes a long press seemed to get it to respond. Pretty bad.

 

So I contacted the place I bought it from this morning and they got a recommendation from the distributor to try a factory reset procedure. It had been behaving itself so far this morning anyway (maybe heat or extended operation is a factor??), but I've done the reset now and will see how that goes.

Good to know that a reset can help with that. Fingers crossed for you that is all that is required ?

Ta. Seems a bit wierd that a reset procedure can help an amplifier. I guess the momentary switches are potentially all going through a microcontroller so that their states can be saved during a power cycle. And so that the same buttons can be multifunction for setting a few settings via hidden menus. Which in turn leaves it open for software bugs...

 

It has been running well for the last couple of days since the reset.

Hello, 

 

I have the same issue with the CXA60. When I try to turn the amplifier on, it directly switch off. However, if I press on D3 source button (the one I use), it switchs on. Same behavior with remote control.

I tried the factory reset, and it does not help. 

 

It is lockdown in France right now, but I'll try to contact my reseller once it is opened.

 

Any advices ?

Hi all

 

I have a CXA80 with the same issue with it turning off if I turned it on using the power button on the front of the unit and buttons not properly responding. The remote worked fine. I was able to work around by holding buttons on the front for a fraction longer than normal.

 

I contacted Cambridge Support and they told me it was very strange and to take it to my dealer which I cannot do right now with lockdown in my country (nz)

 

A factory reset didn't help, BUT, I turned the unit off and disconnected it from the power for 15-30 seconds before plugging it in and turning it on.

 

Problem resolved. At least for now.

 

I assume that there is a processor that controls the inputs from the micro switches on the front needed a reboot. 

 

UPDATE: I've sent a link to this thread to Cambridge Audio. It still might best be dealt with through your dealer but at least they will be aware it's not just one case. They're a small team focused on their product so maybe they'll be able to look into it.

Hello! I’m facing same issues with my brand new CXA60. It goes power off after 2 seconds. I keep trying to make it on several times and after 3-5 attempts it works. Will try factory reset.

Hey guys, I have the same issue but not just with the power button. If I turn mute on, and then turn mute off, it will turn itself back into mute mode again after a random period of time. It keeps doing it after I turn mute off again. I’ve haven’t tried a factory reset though so will give that a go and hopefully that resolves it.

Reads like the amp is going into protection.
Owners manual (page 12) lists five way protection
- DC Protect
- Over temprature
- Over voltage/over current
- Short Circuit
- Intelligent clipping

Indication of protection is given by Direct, Spkr A/B, Mute lights flashing
in particular sequence, see OM.

Do any of the above lights flash?

Strange that CA would call this "strange" behaviour, unless no lights flash...

I don’t believe it’s going into protection mode. It works perfectly fine without any issues until I press mute first. The mute light flashes when mute is on, then goes off when I turn it off....then all is good for a random period of time, then all of a sudden mutes itself. No other lights flash except the mute.

I have the Cambridge CXA60, first gen model.

 

Bought it in May '18 and a couple of months later it was in service as I couldn't switch it on from the power button or remote power. The button light was lit, but no response. Back then I didn't try a factory reset, but the service technician's noticed a loose connection of some kind. Since then it has run perfectly...

 

Until last week!

 

The power button has been flakey again. And this morning the front panel button backlight didn't work. Later today, I came across the factory reset procedure and thought what the hell let's give it a go. And since  doing that reset it I've tried 3 times and both power button and front panel is working perfect. What did it do to fix this issue? I wish I had learnt electronics!

Follow up: it's back to not working again. Sigh

Have since purchased CXN streamer and decided to see if CXA80 was still dead- plugged everything in and it's come back from the dead!- streamer is brilliant but is much happier hard wired than WiFi- great sound and pretty easy to use although it's either the 1920's radio station, Grumpy Dingo (comedy) or WGBO most of the time

Yes, another cxa60 owner with a temperamental power switch. No solution I'm afraid but it does at least switch on after the second try. Sometimes it obliges on the first. Lovely unit but a solution to this issue would be brilliant. Perhaps an issue with the relay?
