Hi,

If you've got a 598 or 596 it's probably got an ageing DVS DVL-720 DVD ROM drive in it.

My 596 did and it died very soon after I bought it (sob). I tried replacing the laser but that didn't work. I tried replacing the drive with another DVD ROM drive from a PC and that was fairly successful but not great.

These are old drives, but I found a supplier for new DSL-720 drives in China prepared to ship small quantities to the UK, through Alibaba. They'll send me one for $41 plus $45 shipping - around 55. I'm tempted to buy two to get the price down a bit - if anyone else interested, PM me.

I can't guarantee anything other than I'd be acting in good faith, sharing the costs, and that replacing the drive is fairly easy - just two connectors and lots of screws...

Perhaps I'm mad. Quite my sick 596 makes me sad!

-Edd

I have a TNT account with a good rate in China.
If there's anything I can be of assistance, let me know.

Thanks for the offer, Albert. I'll probably try to keep it simple, by letting the seller arrange shipping.

Guys,

Albert has advised caution:

Sensible man, that Albert.

Best case: the firmware just has to be of a certain date or later. Worst case: it has to a specific Meridian version. From a 2006 thread on here:

The one I bought on e-bay (the link above) is L008 firmware, from October 2000 so it did not require a firmware flush from Meridian. The Meridian "motherboard" recognized it instantaneously and it plays like a charm. I think Meridian write their own firmware.
Unless anybody can share a good reason for blind optimism, in view of the uncertainties my current plan is to buy a unit or two to test before ordering for everybody else.

I'll post prices next, which are getting better!

I've had an encouraging reply from China about shipping costs:
Quote:
Dear customer

Hope you will have a wonderful day. About the DSL-720:

shipping charge 41USD for 1pcs
shipping charge 50USD for 2pcs
shipping charge 75USD for 7pcs

And the lead time only 5-6 days.

Yes, you need to pay the TAX, but if I mention only 50USD for the customs invoice then you will pay a little TAX fee.

Candy


On a $50 invoice we might pay 20% VAT - or customs might not bother (as below their 9 minimum).

So if we buy 7 drives, the cost could be as low as $52 (33) each delivered to me, plus forwarding within the UK (5-10)

The single unit cost is $86 (around 53) but that's direct to your address in the UK, so maybe ordering individually is not so bad?

THE PLAN
So... as mentioned in my previous post, my plan is to buy ONE drive (or maybe two) to check out first, rather than risk buying seven only to find they're incompatible. I will let you know in a week or so!

If anyone is in a hurry, just let me know and we can share a "risky" order. Or you can buy direct from Shenzhen E-Best Industrial Co., Ltd..

Do these drives need flashing with Meridian firmware?

Hi VK

Yes, that's a good question to which I do not have a good answer. Hence the cautious purchase.

From reading past posts, it might be necessary to get 100% functionality. But whether that missing functionality is important - no idea.

I've never flashed any Meridian hardware but firmware seems to be available for both the 596 and 598 - or at least I can find docs. I'm exploring now.

RS232 ports... ah. Where did I put my soldering iron?

Update: I ordered a single drive mid-week, should arrive in a few days (DHL). Supplier kept changing the prices - mainly in an upwards direction. Annoying, but still worth it - if it works.

Will post an update as soon as I've received the drive and tried it out.

Just realised I've got an MSR remote, not an MSR4 - so no MENU/SETUP button, just hope I don't need the setup menu!

Update: Initial experience

The drive arrived midweek but I'm not yet sure what to say about my experience. I bought it from http://www.e-best.en.alibaba.com/ from Candy, who was very helpful but the language barrier is significant.

Good points:
  • I've received my drive and it's exactly as described
  • t works fine as a CD drive with full functionality (track numbers and time display correctly) and sounds great
  • I could pay with PayPal
Bad points:
  • The drive was manufactured in 2002 so is "new old stock". A bit dusty and maybe less than reliable as...
  • I can't get DVDs to play at all (no disc)
  • The price kept going up (quoted the wrong price, charged for using PayPal, customs charges)
  • The buying process was rather drawn out
I'm still investigating but a bit depressed. I'm going to try tinkering with the firmware and Meridian Configuration Manager, and swapping with other DVD ROM drives to see if any support DVD, however badly. I will report all my findings in a day or two - and leave you (dear reader) to draw your own conclusions.

I may also try swapping the drive electronics with the original drive, if feeling brave.

It may be that my 596 is more broken than I thought - that the core electronics can no longer play DVDs, nothing to do with the DVD drive.

In truth I'm fairly happy with being able to play CDs again - but DVDs would be nice!

Ed

I believe there is a separate laser to read DVD vs CD so failure to read one and not the other suggests a faulty drive I would fear.

12 year old NOS may contribute to this? I hope not, I have a DSL-720 stored away that I bought several years ago for future security of my various M players that use this unit.

Good luck.

Richard

Hi Richard

Yeah, that's my recollection - and concern - too. Infrared laser for CD, red for DVD - and the latter seem to fail more often. Darn.

I guess another way I can prove that the DVD laser is/is not working is by plugging the "new" drive into a legacy PC that supports the EIDE interface. I knew there was some reason for keeping those ancient PCs...

Sheesh

ED;

DSL 710 and DSL 720 use the same laser to read CD and DVD. IF the drive is reading CD but not DVD then there is a very large chance that the fault is the drive, and a very small chance that the fault is in the DVD decoder board (< 10%)

Sound like you have been given a re-worked drive. I have seen a lot of these on the market finding actual new non used drives is hard. several will be re-worked, meaning that the laser assy in the ROM has been changed with a new one, not hard to do but rarely actually fixes a ROM assy. (my experience is about 5-10% of the time.

Most of the failures seem to be on the controller board on the bottom of the ROM assy. and that makes it a write off...

Hi Marc,

Thanks so much for your insight, I can stop beating my head against sundry brick walls then!

So really this supplier in China is being a bit less than honest, and what she's selling isn't worth anyone buying it. That's a bit depressing, but at least I didn't talk anyone else into wasting their money!

Do teeth have skin?

I did perform some more experiments at the weekend which might help make up for it. Maybe. On to the next post: trying random DVD ROM drives!

OK, so the replacement DSL-720 drive I bought from China played CDs very well but DVDs not at all. Wasted a lot time tinkering...

Hang on, I have a number of old DVDROM drives lying around, from old PCs. Would any of them be any good?

Drive 1: Wrong interface (SATA). You want old-fashioned IDE connectors.

Drive 2: Connected, didn't work at all. (Ancient drive)

Drive 3: Connected, played CDs and DVDs. Hurrah? DVD playback seemed faultless. CD playback seemed OK except that the display didn't show track numbers, just track time. Almost good enough but when I paid proper attention, audio through the 596 DAC crackled several times while the time froze - maybe the 596 had got a bit damp, maybe the drive power demands were too much? (This is a Hitachi drive from 2004.)

Drive 4: (Drum roll). Everything seems to be working - played a DVD all the way through with no issues and an excellent picture. CDs played all the way through with track numbers and times, track access etc all working just fine. I haven't actually listened to the audio yet so not 100% certain but I'll connect it to my office system tomorrow so it gets a good work-out and update accordingly.

So my new aim in life is to trawl through skips and find which DVDROM drives work well. I suggest you do the same rather than attempt to buy a "new" DSL-720.

And the highly promising drive that seems to actually work is the... LiteOn HDP118, manufactured in 2010. Just be sure to use an IDE (or P-ATA) drive - not a SATA drive (HDS118).

I suspect that many other recent EIDE drives will work too. You'll just need to make some mounting brackets.

I'll update this post tomorrow evening after a day of critical listening and occasional viewing - while I work at home! Here's hoping.

Thanks Ian!

I've played a number of CDs on the 596 with the LiteOn DVD-ROM drive today, and it's perfect. I haven't played any more DVDs on it as there isn't a convenient video-capable screen in my office.

I think I'm done exploring.

Executive Summary

Don't buy DSL-720 drives, they're going to be old and at best unreliable.

Try an old-style PC DVD ROM drive with an ATAPI, IDE or PATA interface (not SATA). They're cheap and work to varying extents.

There are so many available, but the LiteOn HDP118 worked best for me.

No obvious firmware issues, but I suspect more recent drives are the best bet.

You'll need to make some brackets. I drilled some L-shaped aluminium strip from B&Q or maybe Homebase.

Any easy questions? I'm happy to help if I can.

Hi, I've got similar DVD problems with my G91A. In my case inserting a DVD or a CD gives the message NO DISC frown

So after finding this thread I've just ripped apart an old PC and tried the Sony AW-G170A DVD/CD REWRITABLE DRIVE I found inside.

Initial great excitment as it started playing a music CD. Then the G91A froze! Had to turn the power off and back on before it talked to me again. Same with a DVD. Put the original DSL-720A drive back in and I'm back to NO DISC messages. Interestingly the G91A does not work at all if there is no drive connected. Not even the radio! I also checked the Laser using a smartphone camera and it seems to be doing something. Initially it's flashing red then violet/blue. So maybe it's the detector. Or something else completely!

So "Hello eBay" where I've just taken a flyer and bought a LITE-ON iHDP118-18 4 DVD-ROM DRIVE IDE I/F. Should arrive Thursday so I'll let you know what happens. cool

Hi Adrian

I think I may have started a cult.

Read-write drives obviously do a lot more than read-only drives, I would be quite surprised if they worked in a device that's only expecting a read-only drive. Then again I'm quite suprised when the light switch works.

I think you've got a lot better chance with a read-only drive, certainly worth a go for eBay prices (15ish?).

And think of the fun you'll have making brackets for your new purchase...

Good luck and welcome to the Church of the Moderately Optimistic. (Tricky blighters, acronyms. COTMO seems safe.)

Here's hoping we've discovered the secret of eternal adolescence for Meridian DVD players!

Something else to try?

Amazon - ATA SATA to Parallel ATA PATA/IDE

It doesn't cost much and may be the answer when all the PATA DVD ROM drives disappear.

OK, time for a status update.

The LITE-ON iHDP118-18 (12.99) arrived on Thursday as promised. Plugged it in to the G91A and it plays CDs OK. It trys to work with DVDs but fails. The disk is recognised but just messes up when you try to play it.

So to validate that the new drive is OK, I put it into an exteral caddy, connected up to my iMac and it works a treat. CDs and DVDs all play fine. Put the G91A's DSL-720A drive in and it doesn't load the disk, same as in the G91A.

N.B When trying different DVD drives check that if they have jumpers on the back, they are set to the Master position. Or it definitely won't work!

So I've tried something else. I recovered my 598 which was on loan and swapped the drives between that and the G91A. Result, G91A works, 598 doesn't. So that is conclusive proof that the G91A's drive is faulty as the same symptoms move with the drive. Good old A-B-A test.

Next I tried the LITE-ON in the 598 and joy, it works perfectly. So it looks like the LITE-ON iHDP118-18 is a suitable replacement for the DSL-720A for 500 series kit. But not for the G91A. mad

I've also tried a drive made by BTC - BCO 52321B. It tried by didn't play properly

So if I graft the LITE-ON into the 598 then I'm back to two working DVD players. laugh

That is until the original 598's drive fails sometime in the future - probably next week knowing my luck! So I still need a backup replacement suitable for the G91A.

I've just found replacement DSL-720 laser assemblies on www.aliexpress.com so I've bought a pair. And as an alternative I've also bought one of the SATA PATA/IDE adapters found by TimC - not that I've got a SATA DVD drive yet!

When these bits turn up I'll let you know what happens.

Well done Adrian, very glad to hear you had success with the 598 at least. The G91A is a complete mystery to me.

I tried replacing the laser assembly on my DSL-720 drive, but it didn't work at all. I found the ribbon cable connecting the drive to the laser very fiddly, might have broken it. There's also the challenge of identifying and removing the anti-static link (blob!), which I wasn't too clear about. So many ways to do things wrong!

While I'm tempted to keep experimenting, I think I'm going to hang up my earth strap and reassemble the 596 case.

But I'm going to keep an eye out for another iHDP118 drive. Just in case...

OK, one last update. Two more drives working in the 596:

Hitachi GCC-4481B: 8/10

Made in 2004, a CD-RW, DVD-ROM drive which is a bit long (20cm) so a tight fit in the 596.
  • Plays CDs but only shows track numbers, not times
  • Plays DVDs perfectly

Toshiba SD-M1212: 10/10

Made in 1999, a DVD-ROM drive which is also a bit long (20cm).
  • Plays CDs perfectly
  • Plays DVDs perfectly

Conclusion
This wasn't an exhaustive test, but the crackling problems I reported earlier have gone - probably just the electronics drying out, rather than an issue with the drives per se.

While I'm not suggesting you can (or should) rush out and buy these specific drives, it looks like most plain CD/DVD-ROM drives with a parallel interface will work just fine in the 596. Drives with a CD or DVD writing capability may be less successful.

More recent drives are easier to fit because they're shorter (17cm vs 20cm).

My 596 ate another DVDROM drive recently (a modern SATA drive interfaced via an adaptor - didn't last long).

A few months ago I bought a DRL-200 from Germany for £11 (on eBay) in the (foolish) expectation of obtaining the firmware update that added support for it. Never did (sob). Once I'd got the 596 case open, I gave it a try anyway.

Despite the fact that it's not officially supported by my current firmware (v1.32) it works quite well. It doesn't recognise the disk when I load it, but if I turn off and on again it does. I've only watched one DVD and listened to 4 CDs so far, but those have been rock solid and very nice once it recognises the disk. Early days.

So, if you can get a new DRL-200 drive, maybe it's worth a few quid after all. But I know other posts have suggested otherwise.

Your mileage may vary! I may be heading for a cliff, but I'm enjoying the ride. I'll probably buy another if I see one for £10; PATA drives are getting hard to come by.

Quick update: CD plays first time if I use the Open button to load it and wait for the Loading... message to go away before pressing Play.

If I put a CD in the tray and press Play, that's when the display gets stuck at the Loading... message.

So a bit better than I thought. Patience required.

DRL-200s are available for around £10 + £10 p&p on eBay at the moment - from Germany. Not a bargain, but I'll probably buy another spare or two, to keep my 596 going for a few more years.

After a few weeks' fairly intensive usage (mainly as a CD player, factory CDs): the DRL-200 is working perfectly in my 596. The only limitation I've noticed is that when loading a CD, you must press load to close the drawer, wait a few seconds for the display to update, and then press play.

If you press play to load and play the CD in one go, it doesn't work.

Single drives (from Germany) are £11.10 + £11.10 p&p on eBay at the moment.

Five drives is £39.50 + 11.10 p&p. Must say I'm tempted...

Two weeks more and it stopped working.

I'm not sure but I suspect the drive doesn't turn off when the 596 is on standby - that would explain the limited shelf life.

So the DRL-200 is not a great buy after all...

Sad, but I use the Squeezebox Touch mostly.

Well Ed, you've done everyone else here a service with your endeavours to find replacement drives, and the subsequent long term "living with 'em" review. Thank you!

Thanks George, good to share.

Luckily I am a professional idiot (technical writer) with cultivated ignorance based on boundless optimism. One day I'll find the forever drive that will keep my 596 going... forever.

Latest drive (BTC BDV 316E, an IDE DVD ROM) is doing well, everything working exactly as it should. Like one of those depressing "No accidents for 327 days" signs, I should say: working well for 3 days so far! Installed October 22nd, 2016.

New, it cost me £6.99 delivered, on eBay.

One thing I noticed that might help other optimists out there: if you're using an IDE drive, remember to change the link settings on the drive from SLAVE to MASTER or it won't work at all.

Back to the happy farm.

Call Me Mr Lucky , I’ve just bought a 596 off the Gumtree was informed that it was unused in original box stored in loft for years - so snapped the chaps had off as I’ve been wanting one of these for a long time and couldn’t believe finding a stored unused as new model.
To cut a long story short it isn’t unused at all - the drive inside read discs ok last evening and today all my discs are slipping and skipping so the internal DVD drive must be knackered as it’s acting like a car CD player exactly when faulty slipping and a sliding.
Can anyone recommend a drive which will definitely work at a reasonable price and is there a tutorial on how to take it apart thanks .

Any help before it slides out of my life.

My 596 started showing errors a couple of months ago, to my horror. I've ordered a replacement drive from China which just showed up.

I was thinking to take some photographs of the process of taking the 596 apart and replacing the drive for Duncan's site. I just need to clear the desk in my studio ... and find a weekend that doesn't involve business travel.

I’ve managed to get to the stage of removing the lid that was a bit of a stress not knowing what is inside of it, my suspicions were confirmed as a few of the ? Hex or Torx screws are missing from the bottom!. Have replaced the lid as I was getting nervous when I encountered the brass coloured ? Earthing strips?.

You could take it for a drive to Sheffield and see Rick at audio images I’m sure he could make it less hassle, seeing as your Mac.

@Zygmunt

Can I ask please?, I was thinking of ordering the same drive from China but the firmware I can see says 7.9 on the drive on the eBay listing, mine is firmware 7.32 would this discrepancy make a difference to installation or will the 596 accept any firmware on the ROM drive as long as it’s the correct drive ie, exactly the same as removed.

Thanks in advance and thanks to all who have responded and helped this far.

You may have to update your 598 to the latest firmware to say anything conclusive about the drive's reliability, as it adds support for DRL200 and apparently a few other drives unintentionally in its wake, from my experience.

I ordered a DSL720A from China via aliexpress, with a newer firmware than the original drive. My 596 is running 1.89.2 and detects it as a DRL200 and it works fine apart from a few caveats:

The drive opens and closes much slower than the factory default drive, and it is slower to load media.

The drive is constantly spinning while in standby. I have been told by Meridian that this is to be expected as the firmware isn't fully compliant with the 598/596 but is otherwise fully functional. I was warned though that this causes unneeded wear and tear to the drive, but I'm just happy it works again.

I have not had trouble playing back any types of media, both CD, DVD and CDs containing MPEG files play flawlessly.

If it is reporting it as a dlr-200 then it won't be a dsl-720a

Good that you got it working.

I've replaced two drives now, one on a 598 and one on a 596 and neither span continuously. I must have been lucky.

I don't know (yet). While the (DSL-720A) drive has arrived from China, the demands of the Beloved Client have so far stopped me from installing it, as I do need to be in the same country as my studio!

I promise to write up my experience with the 596 as soon as I update it.

I would like to think that the firmware ( internal to the drive has no relevance at all ), to the Meridian software that’s installed, obviously these machines according to the Bob Stuart Question and Answer of many Moons ago said that it was a modular design which to me should mean that faulty products can be removed and replaced with little troubles. I’m keeping my fingers crossed that you can take the drive out slide identical drive in without event.
