My CD80 is died, please help to find faulty!!

chlo · 14th January 2004, 09:43 PM

Hi DIY members,

My Marantz CD80 was not working properly. It was skipping after 1st, 2nd track. I disassemble the motor and tried to clean it. Afterthat, I reassemled it and played, the player does not respond at all and few lights at front panels also turn on all time. I look and trace everything but can not find any suspicion.

I am really stuck and need your help.

You are giving the answer yourself where to look for the error.

BTW when it is skipping the laser is the usual suspect.

Many thanks Jean Paul,

I put in the laser head of CDM4/19( fully working) in two days ago and the player was working the same. Skipping, skiping!!! so i clean the motor!!!. By the way, thank you for you mod instruction on the CD80. Most of my mod based on that.

Regards.

Sorry to sneak with these questions here,but I know Jean-Paul is the expert at CDM transports.

Jean-Paul,Is the swing arm with the laser lens in CDM1/MKII the same like the one used in CDM4/19?

They look identical.

All Best

Ahem, I would not call myself an "expert", I am just a person with a abnormal interest in CDM's. A nerd so to speak

I did place a CDM 4 laser once in a CDM 1, it worked. Alignment was more a case of luck really. I recall I checked lasers and some of the CDM 4's I have were not 100 % equal. I had a used one that seemed identical.

Thank you for reminding me as I have a cdplayer right now with a broken CDM1 ! Although it sounds stupid I am still searching for new CDM 1's and the thought of using CDM 4 lasers hadn't come up. I am not very familiar with CDM 1 and I can't remember if the CDM 1 at that time was a Mk I or Mk II. I focus more on CDM 4 and CDM 9.

CHLO, I think you should replace the motor with another one. Plenty of broken cdplayers with wornout CDM 1 lasers around. Maybe the one in a Philips CD104 will do the job ? I am not sure if they're the same. Did you resolder the connectors ?

Thanks a lot for the answer.
I have two working Marantz CD players with CDM 4/19.
And I have other player with CDM1/MKII that doesn't detect the disc.
I put both cdm's apart and the arm/laser look really identical.
I put the one from CDM4/19 to CDM1/MKII - doesn't work.
I also try to put arm/laser from CDM1/MKII to working cd player with CDM4/19 (just in case it's not the laser that is broken) and it doesn't work either.
Now ,i don't know wheather the CDM1/MKII is broken (lens or motor) or there is something wrong with the player itself.
It's strange that it actually spins the CD but shows 00:00 time.

If I knew those two must work becouse are identical it would be easier.

Jean Paul,does CD 80 use CDM1/MKII?
Do you know any other,cheap players that have it ,and can be the source for this mechanizm.

I have the link to the list of Marantz/Philips players and used transports but it's been dead for the past three weeks

Hi Jean,

Thanks for suggestion.

I have checked the solder points many times but could not find anything disjoint. I will do it again soon!. I also checked the CDM model in Philips CD104 (some pictures this forum) and it is different from the one in my cd80. I think it may not be swapped. The one I ‘ve seen similar is in Meridian CD Pro.

Chlo,

I just talked to the guy who is an expert at CDM transports.

The transport in Philips 104 is CDM1.You,in your CD 80 have CDM1/MKII,these two are quite diffrent.

He also told me that there is no chance that CDM4/19 laser/arm will work in CDM1/MKII.

The transports that arm/laser is the same as in CDM1/MKII are:
CDM2 and CDM4/31.

All Best

Regards.
