Popping sounds in stereo during playback of burned cd's

I have had my Marantz CDR631 for three years, seldom using it. Lately, There are popping sounds, like a dusty LP, recorded randomly onto material that I burn with my unit. I have removed yhe TV monitor to a distance of 4 feet away. Playback of material recorded elsewhere is perfect.

The cdr631 is a pro unit, should record on any decent quality cdr. If a unit really does need 'consumer audio' only discs it would just spit the wrong discs out like their consumer ones do, not just start adding pops etc. Try a computer grade disc from the same brand as your audio only ones?

Re: Popping sounds in stereo during playback of burned...

Shortly after posting my issue about random "popping" noises in playback of discs recorded on my Marantz CDR361, I found that the problem was that the unit required "music" cd's. I mostly use Maxell CD-R Music cd's with perfect results.

Unfortunately this is normal for the cdr631. Actually, if you remove the disc and play it in another unit, it will sound okay.

A cdr630 twelve years old will not record on any blank discs optical fail on maxell tdk and all you know what discs i can buy for this machine.marantz state discs with a green dye but i cannot...

The manual states that 74 minute 650MB 1-4X disks run best; my machine would not burn anything I had, eventually I found 650MB crrw's on ebay for as cheap as 2 cents a piece, I have a fair number of them and so far every single one has worked. Imation 800Mb cd's seem to work 80% for me.

Marantz CDR-510: Playback is good , recording is distorted

If this brand of media is new to you and the symptom is unique to it, I'd try a different brand.

Monitoring during record would never reveal media problems as there is no immediate playback after record as on old-school 3-head tape recorders.

I've had similar intermittent problems and I never could find a pattern to it except that it always seemed to be on low-end media. My best advice would be to try to find a pattern in your instance and make a change that avoids it. Then publish what you learned for us.

Good luck.

Marantz CDR631 is dead

open it up and take the mechanism out, then you should see a servo PCB screwed to the underside of the mechanism.
unscrew this and where the connecting wires plug in from the main PCB, you should see 2 or 3 fuses which look a bit like capacitors and should be red in colour marked MPXXX eg. MP100?
replace these if you can find spares, if not bridge them with a bit of thin wire soldered in place and then it should switch on once reassembled.
the clicking sound you mention will be the main power supply capacitors running and this is normal.

Looong initializing phase followed by "disc error"


How long have you had the CDR631?

I would suggest a good cleaning of the laser lens assembly. NOT
some cheapy cleaner disc either.

If youre not comfy with messing with small electronics let a tech do it.
Marantz is worth it.

Light doesnt work

Do you mean the Display?
If so ,it's a backlight issue. Some use little bulbs ( NAD and Yamaha)
Take it to a tech ( Ask your stereo store)

What does it do or not do? Does it read the blank properly? If it does and comes up as ready to record you need to check the inputs first and work forward from there. If it comes up with No Disc error or OPC error you may want to buy some different media to see if that solves the problem. We have three of these beasts and they seem to be particular about the media used.Our best luck has been with Memorex and Maxell.
