        Hi this information video very interesting and useful. I have BS9000 it is working very well, I have another CD player with CDPRO2 transport laser problem unable to read CDs. I was left not used last 2 years. After watch this video last weekend, open transport and clean laser, unbelievable my CD transport start working well.

        Since I have many CD player with Philps CDPRO1/2, also service manual and lot information’s out there. But first time I have seen how to remove laser suspension on laser cleaning on Philips CDPRO.  Rajkumar

          Hi all I had used medical Peristaltic Pumps silicone tube “Kamoer Silicone Tube ID: 2mm OD: 4mm they supply minimum 100cm. We can replace for 1000Xnos BS9000 player.

          This size very perfect, existing sleeve 1mm thickness, this tube 2mm will service longer.

          This silicone tube is very soft transport operating very smooth. I have noticed existing damper sleeve too thin this is reason under pressure between mechanical parts cut or deep wear on damper sleeve.

            By the way, MK3 service manual available online not updated schematic, mine type 2572 but PCB32 Rev-V, service manual has Rev-N, where I can find updated schematics. Thanks.

                Seems no one help from this forum?! However, I had solved problems myself, I would like to update this thread will help someone.

                Symptoms:

                1. During CD play sound came out L&R speakers delayed 1 to 3 min (headphone as well same) at the same time digital out can heard sound immediately once CD started readings.
                2. During playing CD intermittently sounds distorted.

                I had suspected PCB32 Input & output select, and sound adjust – IC 2 (shift & store register) HEF4094BT this IC control PL mutes. I have found in my local market D4094B (Chinese?) replaced, then I have more problems, now sounds distorted, intermittent no sounds in CD, FM & Aux in sound. I have ordered HEF4094BT (original) from element 14m and removed D4094B and replaced HEF4094BT, also replace 5nos SMD aluminum electrolytic caps 4.7uf 25V 3nos & 10uf 35V 2nos. My PCB32 different from Mk3 service manuals. As per Mk3 manual PCB32 Rev-N have lot of aluminum electrolytic caps, mine have version Rev- V has 5nos only. Then all problems gone. Rajkumar

                  Hello anyone there please help me.

                  After longtime (5 years more) recently I connect headphone in to BS9000 socket, after that I had problem, delay audio came from the speakers as well headphone, digital output has immediate audio signal! There will be problem in headphone mute circuit or headphone socket?  Thanks

                    When you say digital output i believe the beosound 9000 only outputs in analogue via the following connectors:

                    No, AES/EBU also, i.e. SPDIF via coax. The O.P. was right to suspect oddness since that connector should be outputting whenever the CD data is reading (but not the tuner, of course). Viz:bs9000 manual p-10Hi Thanks for your input. I had connected BS digital output to my DAC headphone amp digital input used coaxial cable.  BS digital output probably directly signal came from CD transports I believe. I try to bypass internal amp and headphone amp. Thanks

                      Hi Mike, thanks lot for your quick response, I will explain more in details

                      BS details: Type 2572 SN: 20514917 probably Mk3

                      a. I had connected BS9000 & BL8000, BS has loaded 6nos cd’s. turned on power both had in standby mode. Now I pressed beo4 “GO” button BS & BL wakeup BL turned on green LED and BS cd start reading track I can see track 1 appear, there is no sound in speakers, BS keyboard I pressed OK button (of CD) display indicating counting example 00.45 still no sound in speakers! After few seconds later I heard sound in speakers! After that everything normal continued playing cd’s without any issues

                      b. Turned on power BS in standby mode, I had connected headphone in BS and now I pressed GO button in beo4 BS wakeup cd starts spinning track no appeared 1 counting started no sound sometime even 3min no sounds, then suddenly heard sounds!

                      c. Turned on power BS in standby mode, I had connected coaxial cable to digital out to headphone amp digital in (coaxial cable) turned on headphone amp power, now I pressed GO button beo4 BS wakeup cd starts pinning tacks number 1 appear, I heard immediately sound after cd start spinning.

                      I believe digital signal came from directly from the CD transport without amplifiers, I was suspect probable causes is CD transport or amplifiers, as per testing c. result overruled CD transport no issues! As per BS9000 service manual troubleshooting guide page 86 defective PCB 32 In/out select, may be having dry soldering in PCB 32?

                      Please let me know your suggestion.

                      Rajkumar
