  • This 1991 Philips CD618 has a problem that is typical for CD players based on the CDM4 mechanism: The gear of a plastic wheel for opening and closing the drawer is broken. Here is how to fix this problem.
    The CDM4 mechanism was also used in CD players by Marantz, Technics, Rotel, ...

    The CDM series it the finest of laser pick-up design; the CDM-1 is built to last forever, all metal, excellent piece of design. The CDM-4 is a later cost saving version with some pieces made of hard plastic, but the swing arm is still high quality. Very durable pick-up, virtually no maintenance required throughout all of its life. As for access speed, CDM were not that fast due to the mass of the pickup and the counterweight which tended to overshoot in case of wide and fast movements. Philips itself abandoned the swing arm with the last of the line CDM-9 in 1995 and started using linear pick-up with the (cheap) series of CDM-12. Beside costs reason (swing arm are quite expensive), it was not possible to use swing arm in CD-ROM, they were too slow for the random access of a data player.

    Even though this was probably a budget/mid range Philips player from back then it is still much, much better built than any CD player made today. I have two CD players that are used almost every day, a Yamaha from around the same time period and a late 80s Technics. The Technics is solid, very heavy and superbly well built and even manages to read CD-R discs and CD-RW discs too even though they weren't invented when it was made. It is also using the same loading belt from when it was new, never had to replace it unlike the belts in cassette players and my Yamaha CD Player's loading belt.

    @badbasstrilogy Před rokem

    Thanks for sharing this, I'm following closely ...Do you know if the CD 604 is the same wheel and belt?
    Mine is orange colour and although the gear was well worn in parts it was a part of the belt's running groove that had been shorn off.
    The motor fires up no problem with it all removed so it must have been jammed somehow, and I couldn't hear the motor trying to do something when pressing the load/eject button so thought it was the motor that had died ,you mention the diode can leak away over time-
    Also I didn't need to disconnect the power arm on this one-
    there's a snapped dowel pin on the corner of the tray bottom left side-it seems to be retaining a small spring- perhaps it's one of the snap locks when the tray is fully closed you feel it connecting ?
    Maybe you know what I should call it and if is available as a part ?
    Thanks again and I'm hoping the wheel and belt are the same so I can order them
    Best regards to you !

    Easy, breezy, beautiful Cover Girl - It's a Philips. It works, nice plastic ribs for extra strength. Mechanisms themselves better than the best Sony, my Sony skips on some 80min CD-R towards the end. BTW, don't be surprised that it can play CD-RW - Philips developed them after all. And this one has removable bottom panel - my Sony from around the same time doesn't, so another big plus for the Flying Dutchman. Volume control, Program, Index - what else would you need. I can't find any Philips based machine in my area - the it's a Sony advertisement made such a following that in North America Philips was treated like low fi brand which is very far from the actual truth. Guess what my post 2001 Sony Car CD player uses as amplifiers - NXP chips. And think of all the NOS Mullard and Philips tubes many people are after, some of the best quality tubes ever made.
    www.soundfountain.com/amb/cd25years.html
    BTW, the TDA1541 with oversampling, dither, and noise sampling was used by Sony untill 1988 when they finally were able to make their own chips that were as good as the Philips TDA1541.

    • @enricoself2256
      @enricoself2256 Před 3 lety +1

      CD-RW requires a dedicated "mode" to be read: reflectivity between pits and lands is lower and with standard pick-up the signal is too noisy to be decoded. CD players that supports CD-RW increase by 10 the amplification of the RF coming from the laser pick-up. The TDA1540 is a 14-bit DAC, but it was used by Philips in a sigma-delta configuration so that thanks to noise shaping it could reach a resolution of 16 bits. Very clever ! I have a Philips CD 204 with both CDM-1 and TDA1540 and despite its age it works perfectly and sounds very good.

    • @DrCassette
      @DrCassette  Před 3 lety

      Interesting, I knew CDRWs were less reflective, but I didn't know CD players could switch in additional RF amplification to better cope with this. I used to have two Philips CD204 CD players, one silver and one black. I ended up selling them because I didn't use them as much as they deserved. But they were absolutely fantastic machines.

    Another note: Because this is a Phillips product, all of the screws are Torx, probably T10. (yes, I know that it may be considered ironic, though the inventor of Phillips head screws is not related to the electronics company)
    Japanese decks use JIS screws (simillar to Phillips head screws, but slightly modified to reduce cam out (colloquially known as "slipping", it acts slightly like a torque limiter).

    • @markmiwurdz202
      @markmiwurdz202 Před 3 lety

      @UsernameNotDefined. You may already know this. The Japanese JIS screws are identified by a small stopped "hole" punched into the screw head next to the cross head pattern. Apparently, there are JIS screwdrivers available specifically for these screw fixings, right down to miniature versions for Japanese cameras and optical equipment. The JIS stands for "Japanese Imperial Standard" although I think the Imperial is based on the Japanese measuring system "Sun" and not UK/USA Imperial Inches.

      Seems to me like the drawer drive does not have enough force to disengage the part that holds down the CD during playback. That's why tapping the CD player helps. Most likely a bad drive belt. Make sure the belt has plenty of tension. If it hasn't, replace it. Also make sure you haven't gotten any grease on anything that is not supposed to be slippery.

It has just developed the same problem with the CD drawer and also will not read the table of contents. Before I take the casing apart, is the remedy the same for the 604? Is there anything else that might cause this? Thank you.

      You could try to very carefully clean the lens of the laser. Use an alcohol based window cleaner, apply it with a cotton swab, use another cotton swab to dry it off. Generally there is not too much that usually goes wrong in the old Philips mechanisms.

    I have a Philips D8884 with same CD-mechanism (excluded loader mechanism) CDM-4, it is a portable radio "boombox". The problem is that it won't read all tracks, stops and shows "error" mostly after track six and higher.I know you are DrCassette however maybe some others know what is actually going wrong? Is this a common problem of the mechanism and easy to fix? I don't think it is a mechanical problem because the arm can move freely at any position. Any ideas? Thanks for any reply.

However, the drawer is closed, so the belt starts to spin around the wheel, making weird noises. I don't think it's normal behavior for the motor to start spinning when the unit is powered on.

Скорей всего ошибка (не искючаю запланированная) инженеров. А может и попросту экономия.

    You keep calling this garbage, but this was actually the end of the period when Philips and Magnavox (then owned by Philips) made some really decent gear. I would say between 1986 and 1993 or so. Philips also had a high quality reputation in the 1970s until about 1981 when they started using crappy plastic for everything; fortunately later in the 1980s they saw the error of their ways.
    In the mid 1990s Philips was in trouble because of heavy competition from Japan and elsewhere, and that's why they started making everything cheaper again, with lower quality materials and components (they didn't make their own components anymore either).
    Bottom line: Philips equipment from before ca. 1982, and from between 1986-1993 is not as bad as you may think. Serviceability was always bad with Philips if you compare it to e.g. Sony, but a lot of stuff didn't need servicing in the first place.

      @@DrCassette You didn't use the word "garbage" specifically, but you did say some negative things about it:
      0:10 "Nothing special" "plastic faceplate" "typical dubious Philips build quality"
      1:19 "Lots of plastic; yes it's a Philips, what did you expect"
      13:23 "The top cover has this weird texture... that's annoying"
      I'm not saying you're wrong, all those are valid comments for this particular CD player. And you praised it too.
      My point is that Philips didn't always make crappy stuff and this was not a crappy CD player at all when it came out, even though Philips was in its "Let's Make Things Better" (but only for the shareholders) phase in 1991 (a lot of people at Philips lost their jobs around that time). The number buttons on the front panel and the display that shows track number and time simultaneously are a sign that this was probably a higher-end model at the time, and in spite of the stupid drawer gear, I'm sure it still works great after almost 30 years. I'd say that's commendable. :-)
