Marantz CD6000 Problem

billman · 6th November 2008, 06:22 AM

Hi,

i posted it also on the other thread with "Modding Marantz CD6000" title.

Today i changed the Diodes 6111-6120 and 6123 and 6125 to 11DQ10

by re assembling i wanted to check if all cables was on and i turned it on without the Laser connected. Since then i become always ERROR 11 (Slegde Error). I testet the lader on a second CD6000 i have and it works.

What is wrong? Can i repair it?

Thanks

So like a kamikazi i did the same with the display. Display was not connected and i turned it on. Result display works also not.

Does something get destroyed when nothing is connected and the board is on?

Hi,

if i had a shorting connection (i mean the + touching the ground) at the positive pin of the 2119 Capasitor (it is a 4700uF 16V ELNA) what would burn?

I am not so good at reading schematics.... here is the service manual:

Probably fuse 1114 or 1115. Remove and check the for continuity, if they are bad, replace them with fuses of the same value. Might be wise to test diodes 6115 and 6116 at the same time, though the fuse should have blown before they did.

So, i took them out (the resistors) and i dont get neither continuity nor resistance. I am going to buy in the mornig some new ones! Lets hope that it was the problem. If yes then i think i know where the problem with the Error was (bad connection at the Clock output) and as i tried to correct it, it got worse (there came the short circuit at the 2119 where i get the + supply for the clock).....fingers crossed....

my question now is: Could also something else go bad appart from these resistors and maybe the diodes (so i can buy them at once tomorrow)?

Thanks for the help

No, can't think of anything else. So did the short circuit from the positive end happen before or after the error message started to come up?

billman · 7th November 2008, 06:17 AM

It happened after but i think thet a had the minor problem at the clock output signal befor and that why it turned on and dint work.

Iwill get the resostors and diodes today and see! I will keep you posted....

and thanks again for the support

Another one: What would happen if i got the Quarz output and ground shortened? (not on the extra clock circuitry but on the player PCB)?I think that maybe the problem that caused the Error message at the beggining.

Circled parts are removed

Do you think i destroyd the chip?

Nothing would be damaged, it just wouldn't work.

billman · 7th November 2008, 08:08 PM

Changed the fuses and it is working!!!!! That very good new since the board and Display seem OK. I must check to see why i get the error message! I suspect the Clock IC....

Thank you very much for the Help
