Second movement, music stops suddenly, no warning, no noises of any sort, just like someone hit "stop".

I thought "is it a power cut" but the Green Naim leds were still showing, then ERR appeared in the cd display.

I opened and closed cd tray and there is no noise or clatter but the cd is not being read- I simply get the (--) message. Different cd's, 2nd puck, same result.

I powered down for 20 minutes (Side 2 of "Horslips - The Man who built America" on vinyl actually) with same result when powered up.


I phoned my dealer in the middle of all this to unfortunately get him as he boarded a Ryan Air flight to the UK for a weeks holiday.


Has this happened to anyone else. Apart from leaving it powered down for a longer period are there any other things that can be tried to resuscitate my CDX2?



SJB

just a thought, is there a process like the Nait5i that "resets the player to default" when you power up?

e.g. the procedure for the 5i is to hold 2 specific front buttons in on power up, it resets the circuits.

rega1

Did you check the DIN/RCA settings with the remote?
Just an idea.

Alas, rega1, there dies not seem to be such a reset procedure for the CDX2 having checked my manual.


Thanks Gian, but I don't think the din/rca setting is the problem as whichever it is set on it should read the cd, which it isn't doing.


any takers?



SJB

sounds like a transport related fault. Off to the factory.

Hi Mr Sloop John B
Sorry to hear that your CD player has temporarily died. It went down in style though, - spooky how it knew that the second movement is often used at funerals.

Don Phillips

but thank heavens you have a turntable to keep you sane in the interim

I got an email from Alastair in Signals, commiserating with me and asking had I tried the cdx2 without the xps2.

As the cd was not being read at all I thought it pointless to swap out the
xps2, but hey he's the expert so I did it anyway.

Put on cd and voilla - "26" - showed up in the display.

Is this man not truly a genius I thought to myself?


But then I thought, but what could have happened as the cdx2 obviously had power even though it want reading the cd.

So I reconnected the Bundy ( I disconnected the xps2 side and reconnected it) and when powered with xps2 again we still had that nice little "26" in the display rather than "--".


I now have cdx2 back with me. I'm unsure whether it was the 24 hour power
down or the reconnection that did it, but who am I to argue. Fingers
crossed all will be OK and thanks to Alastair for showing the interest.



Anyone have any idea what might be happening?

Nope!

I've copied Naim in on the emails, so they might have ideas (other than dodgy connection on Burndy)

Good news (for now at least) though!


Alastair

I think the current CDX2 has quality issues. Mine has already been back and had a new transport put in it. It still won't plat CDR's very well, very hit and miss it will skip on the higher tracks as the laser works its way out to the outside.

Some problems with shop bought CDs, again skipping near the end of the CD. I'm doing an analysis at the moment of what skips and what doesn't looking to see if there is any dirt/blemishes on the CD etc etc. Trouble is that none of them skip in the same place so must be a problem with the player. I'll give it another week of experimentation then then it looks like back to the dealer.

By the way I've tried a different puck, no change.

Cheers

CDX2 "dies" in middle of Beethoven's 3rd.

Was that his unfinished symphony?

Hi prowla,

Beethoven finished all of his nine symphonies, the famous "Unfinished" is from Schubert.

Best wishes

Manfred

Sat down for some serious listening tonight and same thing happened. Music
stopped and after a few seconds ERR showed in display.

I disconnected XPS2, put in link plug and turned on. I had music for about
50 seconds and then the same silence followed by ERR occurred.

Chavez Ravine by Ry Cooder was the album picked on this time.

Silly me...!

I had a similar problem with a new CDX2 over the course of several months. It would skip on new discs at different places but never twice in the same place. Once it froze up. Tried a different puck without success.

Naim replaced the unit with one that has been flawless. They told my dealer that "They have encountered this problem before and it is one of two very tiny surface mount capacitors that is likely defective. The capacitors are part of the power supply to the servo for focus. Thus, when it goes intermittant, it does what you see."

Perhaps this is the problem? Good Luck.

I have an 18 montha old CDX2/555PS (new transport/puck version).
2 months ago I began to experience very intermittent probems which manifested themselves as either a brief crackle from either speaker or a momentary pause in sound. After listening to other sources and disconnecting the 555PS it appeared the CDX2 was the culprit.
On the last occasion while running the CDX2 without the 555PS the music stopped altogether. I immediately switched to the NAT05 via my NAC282; music coming from the system. I switched back to CD; nothing. After pressing STOP and then PLAY sound came from the system.
Unfortunately I had the display off at the time and therefore cannot say if ERR would have been displayed during this event.
While my CDX2 is with Naim I have been using my 13 year old Philips CD850 MkII. Sounds pretty good.
I find it a bit disconcerting that other people have experienced similar problems and seems to put the long term reliability of the CDX2 in question.

I wonder if Naim are implementing a circuit mod as a result of these reported problems?

QC is about checking the correct operation of units before they leave the factory. Power is repeatedly cycled and immediate problems could be expected to show up. Correct operation of the transport is checked automatically over the course of the soak tests.

Problems that manifest themselves months or years after production need to be investigated and the cause, where possible, determined. All we can do here is try to make the repair/replacement process as painless as possible for the owner.

If time shows up a hidden latent problem - we investigate and implement preventative measures but often the failure will be limited to a very small number of components within an individual batch.
Ultimately, the only way to ensure correct operation over years - is to test over years. This is obviously not practical so test routines are developed to absolutely minimise failure over a reasonable lifetime.

Please do not mistake the reporting of faults on this forum with an informative sample of units in use. We have those figures and watch them like a hawk for evidence of past problems manifesting themselves with time.

We have all had products that broke down and those that have worked "forever" but few of us are members of the Hotpoint Users Forum or iPOD Club.

Robert, my cdx2 is the older model (with the superior transport and the deflated price )

I have been refraining from posting more as when one is in the middle of an issue, you are not necessarily in the most objective state of mind. Also I'm cognisant that the forum is not the place to bring up such issues, a bit like scouring graffiti over a shops shutters rather than going in and complaining about the service. Items can break down, I don't believe there is any systemic fault with CDX2's. My post was intended with the hope of getting a reply such as

quote:

There is a button on the underside of the CDX2 beside where the transit screw goes. Press this with the unit powered down with transit screw in position, remove transit screw again, and all will be working perfectly.

Alas as there is no such magic solution, I'll wait for my unit to be either fixed or replaced by Naim and then I'm sure this post will have a happy ending.
