Philips CDI 602 General Maintenance

No service manual for the Philips CDI 602 has been found, and little is known about the Maxi MMC board it shares with the Philips CDI 601.[1][2] The 602 is a 601 with a 3.5-inch floppy drive, so the care of the shared parts is the same; the CDI 601 maintenance page gives the detail of the SmartWatch socket replacement and the port pinouts.[3] Fault-finding is on the Philips CDI 602 Troubleshooting Guide.
Mains voltage selector
[edit | edit source]The 602 takes 100 to 120 V or 220 to 240 V ± 10 %, chosen with the 110/220 V selector on the rear panel (item 14 in the brochure drawing), and draws about 40 W without extensions.[4] Retrostuff, a CD-i repair site, says only the professional and authoring players have such a selector.[5] Check it before connecting the player, and before opening it unplug the mains lead and leave the power switch on for some time, as retrostuff advises for all CD-i supplies.[5]
Floppy disc drive
[edit | edit source]| Item | Specification |
|---|---|
| Controller | DP8473, software-compatible with the µPD765A, with an analogue data separator and phase-locked loop |
| Adjustment | None; "No trimmer or adjustement are required" |
| Data rates | 250 kbit/s MFM (125 kbit/s FM) and 500 kbit/s MFM (250 kbit/s FM) |
| Supported drives | Standard 3.5-inch drives: double density, 1.0 MB unformatted, or quad density, 2.0 MB unformatted; 80 tracks per side; 300 rpm |
| Transfers | Local DMA into a 4 KB sector buffer, interrupt-driven |
The front panel has an FDD LED next to the drive and a push button to eject the disc.[4] The documentation gives no alignment procedure, because the interface needs none, and it lists the characteristics of the standard drives it supports.[6] The player looks for the drive at every start-up. If the check fails, no floppy formats are added to its configuration, and a "load" from the player shell is cancelled after a time-out because the shell cannot match the drive to any format it knows.[7][8]
SmartWatch NVRAM
[edit | edit source]The 602 stores its settings in a Dallas DS1216C SmartWatch RAM socket carrying an 8 KB SRAM chip, for example a Philips FCB61C65LL-70P; the clock and batteries are in the socket.[9] Do not lift the SRAM out of the socket, as that deletes its contents at once. Maxim's recommended replacement for the socket in this arrangement, the DS1243Y-120+, is no longer made; the battery and socket options are described on the CDI 601 maintenance page.[9]
Disc mechanism
[edit | edit source]Discs load in a caddy into the CDM 9 mechanism.[4][10][11] ICDIA calls the CDM 9 generally very reliable.[10] The World of CD-i's checks for a disc that will not spin, a slipped turntable and a damaged flat cable, are on the troubleshooting guide.[11]
Preventive maintenance checklist
[edit | edit source]- Check the voltage selector before powering the player.[4]
- Check that the eject button (5) releases a floppy.[4]
- Load a test floppy with the player shell's "load" button to confirm that the drive is detected and read; see floppy faults.[8]
- Check the date and time after the player has been off for a while; a lost clock points to the SmartWatch batteries.[9]
- Play a disc and watch the Reading Disc LED, which lights when a CD-i disc is loaded and flashes while it is read.[4]
