Philips CDI 660 General Maintenance
.png)
No service manual for the Philips CDI 660 has been found, and none is listed in ICDIA's service manual index.[1] The procedures below come from a complete strip-down of a CDI 660/00 published at retrostuff.org, from retrostuff.org's notes on the Mono IV board and its power supplies, and from Philips' service manual for the CDI 220/80, which covers the same main board family.[2][3][4] The Philips CDI 670 shares this cabinet and power supply; its page lists what differs.
Safety
[edit | edit source]- Unplug the player and leave its power switch in the on position for a while before opening it, so that the large filter capacitors in the power supply can discharge. retrostuff.org warns that these capacitors can give an electric shock if they are not discharged.[5]
- The 660's supply is the 20PS307, an internal Class 1 (earthed) unit with an IEC C14 inlet. Use an earthed mains lead.[5]
- Philips warns against touching the inner pins of the rear connectors, as static discharge can damage the player permanently.[6]
- The disc mechanism uses a laser. Philips' manual says that only a qualified service person should take the cover off, because of the risk to the eyes.[6]
Back up the NVRAM first
[edit | edit source]The 660 keeps its settings, files and any start-up message in a 32 KB SRAM sitting in a battery-backed DS1216C socket. Taking the SRAM out of the socket wipes it immediately.[2] Copy the contents to a PC first with a null-modem cable and the CD-i Link program, as described at retrostuff.org.[3][2]
Strip-down
[edit | edit source]These steps follow retrostuff.org's strip-down of a CDI 660/00 and start with the top cover already off.[2]
- The 22ER9956/40 mini DVC sits in a plastic frame held by two screws, one inside the player and one at the back.[7] Remove both, bend the plastic holder up and lift the DVC out.[2]
- Three screws hold the CD loader assembly. Pull the tray out to reach them: one is in plain view and the other two are inside the two holes in the tray close to the front panel. Take off the front bezel, push the tray back in and lift the assembly carefully. Three connectors underneath it have to be unplugged.[2]
- Remove the two screws holding the main board and unplug all the cables; the Mono IV board then comes out.[2]
Reassemble in the reverse order. The mechanism is a CDM 12.1. Philips' service manual for the 220/80 treats it as a replacement assembly, service code 4822 691 30278.[8][4] retrostuff.org also lists the VAM1201 and VAM1202 as mechanisms found on large Mono IV boards.[3]
NVRAM socket
[edit | edit source]Every DS1216C socket that retrostuff.org has opened contained two cells. Most were still working, but the socket is no longer made and the cells will run out in time.[9]
Removing the socket
[edit | edit source]The socket is soldered from both sides and is hard to get out. retrostuff.org held the board in a PCB holder, desoldered the lower row of pins with a desoldering gun from below and an iron on the other side, and had to bend the socket up carefully to reach the upper row, which the DVC socket partly blocks. A 28-pin IC socket was then fitted, with the DS1216C and the SRAM on top; there is enough room for this stack under the CD tray.[2]
Replacements
[edit | edit source]Maxim recommends a DS1244Y-70+ NV SRAM with phantom clock in place of the socket and SRAM; the Glitch Works GW-1244-1 module is an alternative. retrostuff.org has had reports of extra batteries being added to DS1216C sockets using tutorials written for the similar DS1216E; follow the warnings in those tutorials.[9] Battery and corrosion damage in general are covered on Battery Explosion, Capacitor or Corrosion Damage.
Size links
[edit | edit source]On large Mono IV boards the NVRAM size is set by resistors: 0 Ω links 3244 and 3270 select 32 KB, and a 4.7 kΩ resistor at 3241 selects 8 KB. Leave them as they are on a 660.[3][2]
Fuses
[edit | edit source]| Location | Ref | Type | Protects |
|---|---|---|---|
| 20PS307 power supply | 1101 | T1.0A L 250 V glass fuse, 5 × 20 mm | Mains input |
| 20PS307 power supply | 1200, 1201 | MP315 (TE5) | +5 V outputs |
| Mono IV main board, grid square F1, next to the power connector | 3255 | MP100 (TE5, 65 V 1 A), Philips 4822 252 51173 | −5 V rail |
| Mono IV main board, grid square C1 | – | Resettable PTC fuse RXE065, Philips 4822 116 40238 | +5 V to the controller and serial ports and the RF modulator socket |
[5][10] The MP fuses are Wickmann (now Littelfuse) 398 series TE5 parts. After replacing a fuse, measure the supplies at both ends of the cable between the supply and the main board.[10]
Power supply connections
[edit | edit source]The 20PS307 feeds the main board through connector 0201 and the combi panel through 0202. retrostuff.org's pinout:[5]
| Pin | Signal | Goes to |
|---|---|---|
| 0201 pins 1, 2 and 4 | +5 V | Main board 1001 pins 1, 2 and 4 |
| 0201 pin 3 | +5 V standby | Main board 1001 pin 3 |
| 0201 pins 5, 6 and 7 | Ground | Main board 1001 pins 5, 6 and 7 |
| 0201 pin 8 | −5 V | Main board 1001 pin 8 |
| 0201 pin 9 | Standby control | Main board 1001 pin 9 |
| 0202 pin 1 | +12 V | Combi panel 1001 pin 1, and on to main board 1021 pin 9 |
| 0202 pins 2 and 3 | Ground | Combi panel |
retrostuff.org has not yet confirmed where connectors 0203 (+5 V) and 0205 (+12 V) go.[5] On a Mono IV board −5 V is easiest to reach on pins A1, B1 and C1 of the extension connector. retrostuff.org blew fuse 3255 on a CDI 470 by slipping with a probe there and shorting +5 V to −5 V, and now clips a crimped 3-pin JST-PH (2 mm) plug onto those pins instead of using bare probes.[10]
50/60 Hz switch
[edit | edit source]Two 10 kΩ resistors in grid square C2 on the track side set the STANDIN! signal (pin 58): 3290 to ground gives PAL timing, 3203 to +5 V gives NTSC.[3][2] retrostuff.org removed 3290, ran three wires (ground, STANDIN! and +5 V) to a single-pole changeover switch with a 10 kΩ resistor on its centre pin, and mounted the switch in one of two holes in the bottom of the case, on the right-hand side; the switch is shorter than the feet. Over the RGB Euroconnector most televisions show the 60 Hz picture in colour. Players without RGB give only a black and white picture after the change unless the crystal oscillator is changed as well.[2]
