Goldstar GDO-203 Troubleshooting Guide

The Goldstar GDO-203 Alive II is a top-loading console with the Anvil chipset and a Hitachi laser, so little of the GDO-101M's drive work carries over to it.[1][2][3] No GoldStar service information for it has been found. The notes below come from the 3DO Development Repo and from the console's rating plate; for capacitor symptoms in general see Capacitor Failure Symptoms.
Things that are not faults
[edit | edit source]- The GDO-203 refuses CD-Rs by design. It and the GDO-202 are the only 3DO models that do.[4]
- A GDO-203P is a PAL console rated for 220 V, 50 Hz; its plate reads 9 W.[5] On an NTSC television its picture may roll or show in black and white, and an NTSC GDO-203 on a PAL-only set may show nothing.[4]
- Some games run on only one of PAL and NTSC, and may crash or glitch on the other without saying why.[4]
No video, or a poor picture
[edit | edit source]On one owner's GDO-203 the video grounds were not soldered to the board: they reached it through the RF shield and its screw. With the shield or the screw missing, the console had no proper picture. Refit the shield, or at least the screw, before chasing a video fault.[4] The 3DO Development Repo's general checks also apply: try each output, look for cracked joints on the sockets, and check the supply and video capacitors.[4]
Region conversion
[edit | edit source]The Alive II's video standard is set by two parts, according to the 3DO Development Repo:[6]
| Region | X101 | R10P |
|---|---|---|
| NTSC | 49.09 MHz half-can | Not fitted |
| PAL | 50.00 MHz half-can | Fitted |
R10P connects to the VRAM and to ground. Whether simply fitting R10P works is not yet known. One PAL conversion that worked used a resistor of about 47 kΩ (the value is queried at the source) from a VRAM signal to ground, but was not confirmed free of picture glitches.[6]
Disc reading
[edit | edit source]The laser is a Hitachi HOP-E1, the pickup also fitted to NEC's PC-FX, which helps when sourcing a replacement.[3] Before replacing it, clean the lens and rule out the capacitors and the disc itself, as for any 3DO.[4] The adjustment pot on a 3DO laser needs an oscilloscope to set correctly; turning it up by trial and error can destroy the laser or blow the fuse.[4]
