The Philips CDI 370 is a portable Compact Disc Interactive (CD-i) player built for Philips by LG Electronics, then trading as GoldStar, and based on GoldStar's own portable CD-i design. ICDIA notes that it has the Digital Video decoder built in and a rechargeable battery, and that it is far more compact than Philips's earlier portable players, the Philips CDI 350 and Philips CDI 360.[1] It shares its board design with GoldStar's GPI-1100M and GPI-1200M and the NBS Lookman ID.[4] No service manual for it has been found.[3][4]
Hardware
[edit | edit source]ICDIA's comparison table lists the 370/00 with the second-generation player shell, RC6 infrared, 32 KB of NVRAM, built-in Digital Video, a 720 × 234 display, a composite (CVBS) video input, and LG Electronics as the maker.[2] retrostuff's notes on a partly dismantled unit identify the main parts:[3]
| Function | Part |
|---|---|
| Processor | Motorola MC68340 (IC101) |
| VDSC | MCD212 (IC102) |
| VMPEG | XCD251 (IC103) |
| DSP | Motorola DSP56002 (IC104) |
| System ROM | TI TMS27C240-15 EPROM (IC106), ROM ID 11, release 1.3 |
| CD RF signal processor and CD DSP | Sony CXA1372AQ (IC302), Sony CXD2500BQ (IC303) |
| RCHIP and ADPCM (as identified by retrostuff) | Sanyo LC8954 (IC305) |
| Audio DAC | AKM AK4319VM (IC201) |
| Video encoder | Analog Devices AD722 (IC112) |
[3] The display is a Unipac UP661A-1 panel with its own driver boards.[3]
The player needs two supply voltages through its 5-pin mini-DIN power socket: 21 V at 1.7 A and 5 V.[4] The power board carries an LM2576 step-down regulator, an LP2950 regulator and two connectors for the battery.[3] The NVRAM is backed by a CR2032 cell in an accessible compartment on the bottom of the player, so it can be changed without opening the case.[5] A PAL/NTSC switch is fitted, so no 50/60 Hz modification is needed.[4][3]
Known faults
[edit | edit source]- retrostuff's unit came without its power supply. Owners have built replacements from a notebook supply of 20 to 21 V and a 5 V USB output wired to a 5-pin mini-DIN plug.[6][4]
- On retrostuff's unit the PAL/NTSC switch SW102 reset the player but did not change the standard, leaving it stuck in NTSC. Cleaning the contacts and re-greasing the small spring cured it.[3]
- The same unit's display did not work because a small transistor or regulator, Q701 on the display board, had failed; its type is not yet known.[3]
