Question about Marantz Audio Players & Recorders
Posted by Anonymous on
This sounds crazy but it works for some reasons. Marantz CDR500 would not read and initialise some blank discs but no problem with reading finalised ones and erratic would and would-not work. Tried cleaning lens and even blowing ar through it. Before I wasted money in air I thought why not try hairdryer into open tray and lens area and just for measure across blank CD. I know this sounds weird but it worked every time and machine will read any make of disc like this. I do not have any scientific explanation only the fact that it works!!!

You cannot replace the new lens your self. coz there are some process to replace a new lens. withour much knowledge of servicing you might damage the new lens too.
try to find some substitute for your technics lens

the laser in your DR-6000 is exactly the same as what's in the philips cdr-775 and cd-r-770.
a brand new laser for these are very hard to get hold of and are very expensive. personally i would look out for the above philips models on ebay for less money then take the whole mechanism out and unscrew the servo board and then fit the marantz servo board in place of it and fit it back into your recorder.
i have done this on numerous occasions with no problems.
hope this helps.

Check the small signal transistors BC338 and BC328, they're under the transport mech and will be near where the spindle motor plugs in to the PCB.
One of the transistors acts as a brake which momentarily puts the motor in reverse polarity to stop the CD rotating during 'stop' or 'open tray' modes. The reason the CD is spinning backwards is that the transistor which drives the spindle motor forwards during playback is faulty and is triggering the braking transistor hence spinning backwards.
The transistors should be 'BC328-25' / 'BC338-25' (25v)
Replace these and all should be well.
Hope this helps

Before you replace the optical lens try this first.
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust the lens can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.
2.Replace the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
If the above steps didn't cure the problem, high chance that your optical lens was faulty, click this for the replacement http://shop.ebay.com/i.html?_nkw=Marantz+cd5001&_sacat=0&_odkw=WS-65809&_osacat=0&_trksid=p3286.c0.m270.l1313.
If you can't do the job yourself, I would advice you to look for a
professional to troubleshoot the symptom.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
