My first CD player ❤
Very good materiał.very help full.thank you
Hello, when I bought this device, it had exactly the same problem. After watching your training clip, I first replaced the belt and the 1000 microfarad 35V capacitor. The problem was solved by about 95%, and it only gave errors sometimes, but after replacing the 6800 microfarad capacitor, I replaced it, the device no longer works and only gives error messages, what is the reason?
Screwdriver head is called Torx :) and my CD160/CD371/CD480 will read cdr which has the same CDM2/CDM4 mechanism.
Great video...you made me laugh, you made me cry..in the end it reads cdr....great job!
One fun detail - I worked for Philips from 1997 - 2000 in the Videofactory IR3 in the Gutheil-Schodergasse 17 as a Firmware Analyst in the QA822 - hahaha and during this Video I can't remember of the name from the Torx!
Thank you for that what I forget to tell - hahaha :-)
I have the CD960 from this era. It’s a wonderful machine but the CD tray sticks. I’ve changed the belts but I need to get back inside it to lubricate the rails.
I would also buy me the CD960 but this was for me to expensive ans so I bought the CD430 - only. weakbit
TDA 1541 😍😍😍
Love your hardware experiments! 👍
Thank you!
I'll do more videos in case like this repair and the CD-Player community. I also must ask about the situation - shall I show you more inside the service-manual i case of the understanding more the inside of the electronic so I can do!
At this year MacIntoch has sell a MCD 7000 with the same mechanic and electronic ! But 20 x more expensive.
Hello please send a Link to this Video here in this commend line - this will be cool! weakbit
Didn't show how to adjust the laser power; just said that he did it !!
lowest as possible due the EFM package looks good like the eye pattern must be in a good shape. (with a original pressed CD)
Ok done, changed the belt, only the belt, had a spare pulley but did not touch it. Order to do it: I suppose Drawer Schnappi could have been left in place: ah no, otherwise front plate can't betaken off. So try to pull out the drawer completely, as you need to free 2mm to place the new belt. you do not touch the motor. Otherwise screw off the 1 screw in the bottom (long screw for this small plastic part), the 2 screws back of transport, 1 screw in front of the transport. I had problems to reattach the spring from the laser cover. Take a photo before manipulation.
This was my first cd player I bought it in 1986 I used it for about five years then upgraded to merantz
That's cool in case of my non existing money in 1987 I bought at a dealer the CD430 for lower money - Marantz was unreachable for me in my position. weakbit
Hi Weakbit. I love your video and your cheerful style, thank you!
I have just stripped this down, re-soldered the power lead socket and rebuilt it quite successfully. All back together, but and seems to work fine except the flex-PCB has slipped out of the white plastic retainer on the motherboard. Please can I ask how on earth you fitted it back successfully???? As you say it's only about 5cm long and there's no room for your hands!!!
Many thanks,
Dominic
Hello Dominic - I remember I do that with my left hand and with my 2 fingers but it can also be that I use a Pinzette too. I remember this on the left/front side this little plastic connector and it still stand straight vertical - but you must open it to move a Pinzette the white around frame and lift it to the top so the connector is open if you don't do that you can't insert the flex-PCB into the connector back. Thank you for watching weakbit
Tnx for sharing sir
Belts and defective motors are common. I also find defective laser pickups but often they aren't available or the cost is too high.
I see that also so defect belts are the main in my eyes. Motors are also and Caps often too. And dirt behind the lens that is also very difficulty to clean in case of dis-assembly the laser lens and assembly it again.

Hi, can the CD473 board be use for conversion into a Bluetooth DAC. How can it be done? I took out the board and threw away the casing...thinking of toying with it.
Hi weakbit. Thank you for making and posting this video. Kindly, in your estimation, then, if I understood you correctly, the main issue were the weak/cut belt, and ¿the 'adjustment of the monitor of the laser diode/sensor up closer to the media/CD'? Thank you for making & posting this video. Thank you again.
I think there was the power supply at the first and the second the laser was also inside the lens dirty. So I see that issue at this old one CD-Player! Thank you for watching. weakbit
@@weakbit633 I see. Thank you for the kindness of a reply. Thank you for making and posting your videos. (Nice work you do). God Bible[Bless].
@@tonyd1149 I'm very sorry that I can't
not answer in time so i do that later - sorry for the inconvenient delay! Shall I show you more details in the service-manual? or is it enough what I show? In case of the runtime of my videos.
@@weakbit633 Dear Sir, no worries, please. (I realize that you're busy with many things). The kindness of your replies is a blessing (to us). Thank you so much for your videos. (Great skills you have). Thank you again. I wish you much success. God[Bible] Bless.

Hello! I have a Toshiba xr-z70 cd player. I have a question, if you don't mind. My CD player opens the drawer when starting from the power button. What would be the problem? Any advice is welcome. I understood that this is the common problem with these models. Thank you very much. A good day.
normal it should be closed after power up. There is a end switch and if this is not in position - the µController dedect it as not close it could be that it open the tray after power up. I think is this end switch. This end switch could also positioned under the drive on a gear or wheel! this is much complicate to repair but I do that some times in a other Video but I don't know this model from Toshiba XR-Z70. weaktbit
@@weakbit633 Good evening. I checked them on the spot and they seem to be good, there are 3 of them. I will take them out and check them more thoroughly. Thank you very much. A good evening.
@@weakbit633 Good evening. I checked them and they are all good. I don't know what else to do. A good evening
Hi I have a CD 473 which has a problem with skipping in higher tracks of the CD. I have cleaned the laser lens with isopropyl and this has helped somewhat. I will order new capacitors for the power supply. How did you adjust laser diode? Is this the potentiometer shown in section D4 of the PCB at 18:09 in the video? Turn clockwise to increase gain? Thanks from New Zealand.
Hello Rory, I'm sorry to hear that but if this Laser is on the end of live it is a little help to turn the current higher (Trimmer 3528) but this help only a little - the light intensity is gone. The other story is that this Laser-Pickup is never more in production and you can get in nowhere there is nothing on new-old stock only the complete drive I think. It is a CDM2/0500 drive and this is very rare on the market. But search at eBay sometimes is there a drive available. The issue is the Laser-Diode and this Diode have 3Pins and the organization is other then the Laser-Diodes they are on the market. The Pin 11-8 Monitor-Diode, 11-9 Laser-Diode and Pin 11-10 GND. But the Anode or on Pin 11-10. Newer Laser-Diode with Monitor Diode have the Monitor diode build in inverse so you can't use them. The Laser-Diode Anode is connect to the Kathode from the Monitor-Diode and this is the issue. I would inverse the measurement current from this diode and then the IC TDA5708 is died in my Player. What did you said if we made a Laser-Pickup in this style by our own with a 3D Printer? I've one PhotonS here in my kitchen! That will be nice if we print one Laser-Pickup out. weakbit
Tolles Video! Was glaubst du war der Grund, dass die gebrannte CD zuerst nicht erkannt wurde? Der dreckige Laser oder die alten Elkos?
I thought that the electrolytic caps are so old and making noise at the supply also the dirt on the lens but only clean it with spit! This Laser pickup is inside also dirt from smoke and dust.
Bitteschöne I can't make a answer so well in german.
Google translator Eng2Ger => Ich dachte das die Elkos so alt sind und beim Zuführen Geräusche machen auch der Dreck auf der Linse aber nur mit Spucke reinigen! Dieser Laser-Tonabnehmer ist im Inneren auch von Rauch und Staub verschmutzt.
Sir I have pioneer pd 106 the problem is won’t play won’t spin spindle drive the laser had light what is the problem of my CD player? Please can u help me? Tnx
download this service manual pioneer_pd-106_cd_player_sch.pdf on the left side top is a IC LA6520 measure pin 7 this is the spindle drive IC out and/or measure the pin8 this is the spindle from controller. Also check D218 Z-diode 6.2V. this are the things what I'll make a check but I don't make support for repair and I don't repair CD-Players for other peoples I'm only making Videos. In case I've no time for all this jobs - so sorry. Thank you for watching weakbit
@@weakbit633 thank you very much sir for helping me im very happy you answered my question about the pd 106 sir if i cannot find the voltage pin #7 or # 8 what is the problem sir ? The ic LA6520 is the problem? Tnx and more power to your video I really love to see you🙏 keep smiling 😊 sir how many volts pin 7 and pin 8? Tnx again🙏😀
Hallo. Ich fang jetzt an den Riemen zu wechseln da die Lade nicht mehr automatisch öffnet und schliesst. Was brauche ich zum reinigen? Balistolöl und 100% Alkohol und Ohrstäbchen. Es wird auch Glasreiniger benutzt um die Linse abzutupfen. Geht Isopropylalkohol, habe noch welchen. Danke.
No Oil - No Alcohol - No Isopropylalcohol! - don't put any oil in your drive! for the lens use spit & a cotton stick this is a perfect degreaser for the fat on the lens. Thank you for watching! weakbit
you mean saliva, my own spit ?! Thanks a lot. My CD880 plays some tracks, others not and with different CD’s different tracks are unplayable. Apparently there could be magnets from the laser which got losen. Only problems.
Yes the own! - CD880 from Philips. I don't think so there are magnets they are falling apart this is a normal iron (Fe) and coils that making the Magnetic field to position the lens up/down. I think more on the low laser light that less reflecting the signal back from the CD. What do you have for a CDM? mechanism?
@@weakbit633 I think it was written CDM 1 Mk2. But oh wonder now it played 1 complete CD (female finnisg singer Tara) and Dire Straits, Pearl Jam ... made problems. I can't understand why but glad it played 1 total CD.
@@thevintagehifiambassador8524 CDM1 MK2 is never more available - did you clean the lens?
Hi. Was the belt replacable easily?
Yes it is.
@@weakbit633 great. Do u have the exact link to one or the size? Cheers
@@CM-dw3gh Hahaha - I can't remember which size it was! But at the part list - part104, 4822 358 10115 maybe you can order it some where. I don't know. which wonder at eBay-Artikelnr.:284696360262 weakbit

Your video is very "interest"...
the CD471 from Philips was my first own CD-Player that I bought in 1987! It is near the same machine like the CD473 (the 473 are only have a button more the green one). I was very proud in 1987 that I've one of this new CD-Players in that case that this cost a lot - around ATS 3400,- Schilling this is in a index calculator into todays money => The equivalent of 3 400 ATS on 31 January 1987 is 7 541.53 ATS on 19 July 2022 (click on the links to convert amounts to other currencies) Inflation over the period : 121.81 %, used index:ATCPI2013 (Statistik Austria (Vienna)), Initial Index: 56.16, End Index: 124.57 Today's equivalent in euros of 7 541.53 ATS is 548.06 EUR weakbit
