The Philips CDI 670 has no published service manual, and no repair reports specific to it have been found.[1] It shares its user manual with the CDI 660 and its main board family with the 660, 615 and 740, so fault-finding follows the Philips CDI 660 Troubleshooting Guide, which has the full owner's checklist, the low-level test items and error codes, and the service shell procedure.[2][3] The notes below cover the points particular to the 670.

Settings that look like faults

[edit | edit source]

The shared manual describes a protected mode for exhibitions, demonstrations and point-of-sale use, and lock modes set by the supplier, so several of its "Before requesting service" entries describe settings:[2]

From the CDI 660/670 user manual
What you see Cause What to do
No open icon, "TRAY LOCKED" on screen, OPEN key does nothing Protected mode Switch off, then switch on while holding PLAY for at least five seconds
No options icon Protected mode, or the supplier has disabled it Check protected mode
A "no entry" sign when a disc is loaded Lock mode set by or for the supplier to allow only certain discs Use a disc the lock allows
A different start-up screen or message Changed by or for the supplier See below

[2] The start-up message is set with the CDI 660/670 Key disc (PIN 3094) or held in a ".keycontrol" file in the NVRAM; retrostuff.org's remedy for its ROM and software changes, the start-up message among them, is to delete the NVRAM or refit the original ROM.[3] Back up the NVRAM before clearing it.[4]

Peripherals

[edit | edit source]
  • Connect and switch on any printer, ZIP drive or RS-232 device before switching the player on.[2]
  • A wired controller in input 2 switches off the infra-red remote.[2]
  • For group working, check the RS-232 links between players, that every player shows the start-up screen, that all are switched on and that there is only one master. Files copied to memory must be smaller than 32 KB.[2]

Diagnostics

[edit | edit source]
  • The 670 ROM lacks the service shell module, so the test plug used on other CD-i players makes it reset in a loop. retrostuff.org's workarounds for the 660 (a borrowed CDI 490 ROM, or a patched DVC ROM) are described in the 660 guide; whether the patched 660 DVC ROM suits the 670 has not been tested.[5]
  • For the low-level test, Philips' procedure on the Mono IV board is a VT100 terminal on port 2 with the space bar held at power-on.[6] Which of the 670's ports carries it is not documented.[2]

Hardware faults

[edit | edit source]

The faults known on the shared Mono IV hardware, with the checks, are tabulated in the Philips CDI 660 Troubleshooting Guide. In short: no sign of life points to the 20PS307 fuses 1101 (T1.0A) and 1200 or 1201 (MP315);[7] no picture or a rolling one, with the tray opening by itself and the disc motor running on while the low-level test passes, points to the −5 V fuse 3255 in grid square F1;[8] and lost settings or clock point to the cells in the DS1216C NVRAM socket.[9]
