My PWD experience random hanging during playback.

When it hangs the power is on, display is on. I cannot stop/play or eject the disc. Looks like the transport has “jammed”

The only solution is to recycle the power by turning off and on the power on/off button at the back of the unit. 

After the player re-initialize, I can stop/play/eject the disc. 

Until the next hang.

Does anyone have similar experience and can share how to solve the problem?

Is it a hardware fault that I need to send the unit to the dealer for service?

thanks a million for all advises.

 

regards

I just bought a refurb from Music Direct and I have to say the unit literally looked and was packed like brand new…  Thank you PSAudio for that. 

However, on playing the 1st disk through it today, it hung exactly as mentioned.  Perhaps there is a firmware update that I need? 

 

Regards,

Chris

Welcome, Christopher

Have you continued to have problems?

It is worth checking whether the unit has the latest firmware.  I have attached the latest for you.

Here is a link to how to load firmware, click.

I had some random hangups, so I would Optrix, and sometimes Microsmooth. It helped, but when I contacted service, they had me send it in.

It hasn’t hung up since I got it back. And mine was like new also. It is a really nice transport. I don’t have a PSA DAC, so I can’t make use of the I2S output. I always seem to run a generation behind, my last transport was a PSA Lambda.

If finances allowed I would have a DMP and a Directstream.

Same problem for me: my new PWT freezes randomly during playback. 

I turned it in twice to PS Audio for service. Customer service was helpful, but they did not solve the issue.

Very frustrating to have the pwt freeze randomly and the music stop dead in its tracks after spending that much on a transport!!

If anyone knows how to fix this, please let us know.

Regards,

Phil

My understanding is that the PWT does not use standard error correction.  Instead, it reads each sample multiple times to insure that it gets the same data from multiple reads.  The only CDs I have had a problem playing had a scratch or defect that prevented data from being read correctly.  So, where even a cheep portable player could play the CD because of standard error correction, my PWT would stick or skip due to scratches.

While I appreciate that PS Audio wants to insure that a disc is read with the correct data for each sample, I would prefer that if it can’t retrieve the same data from multiple reads, that it would then use standard error correction to process the sample and then move on.  Having less than perfect data samples due to disc defects would be far less annoying than having the disc refuse to play.

There have been times when my PWT gets completely stuck and won’t respond to any commands on screen or from the remote is when I leave a disc on pause or stop for an extended period of time, like not removing a disc when it is finished.  I have not been able to figure out a pattern where I can reproduce this problem at will.

In my case, the CDs don’t seem to be the problem. The pwt freezes on CDs that have played on it several times without problem before. And when I do a power off and on, most of the time, it plays without problem the same CD where it froze.

By the way, I have the latest version of the software installed (1.23).

This is quite a few months after the fact, but I’ve had this same problem with my refurbished PWT. A question for those of you who have also experienced it: do you have an ethernet cable plugged into the PWT? Did you do your latest firmware update with the cable plugged in? What seems to have solved this problem for me (for now anyway) is re-installing the firmware, whichever version you like best, without the ethernet cable plugged in, then re-attach it after the initialization completes. Has worked seamlessly for me ever since (just a couple of days now, so not all that long). Not sure why this is the case, but so far so good…

I am having the exact same problem as Bill S, with NO Ethernet connection. This flaw is definitely not related to that, I’m convinced it has to do with how the PWT reads discs as previously stated.

It’s going in for repair, but I’m unsure how this will be resolved. We’ll see.
