Casio Loopy
| Preliminary Information | |
|---|---|
| Release Year | 1995 |
| Leak Risk | Medium |
| Batteries | None |
| Mounting Technology | Through Hole, SMD |
| Capacitor Types | Aluminum Electrolytic, Ceramic |
| Destructive Entry | No |
Known Issues
High chance of leakage on IO board
Causes
- C504 installed backwards on all revisions due to incorrect board markings. If it hasn't leaked yet, it probably will.
Solutions
- Replace C504 with a new cap in the correct orientation.
- Alternatively leave C504 unpopulated, no noticeable change in operation.
Audio is quiet or has uneven stereo levels
Causes
- Dry capacitors in audio path.
Solutions
- Replace C254-C255, C261, and C263-C266. Total 7 caps, along the rear edge and rear-right corner of the main board.
- Capacitor type is not critical here. Ceramics of the same or greater capacitance value can be used but may change the sound slightly.
Video is dark, unstable, or has a visible gradient
Causes
- Dry capacitors in video path.
Solutions
- Replace C501, C502 and C533 on the IO board.
- Higher capacitance value can be used to improve video quality.
Disassembly Notes
Remove screws on the bottom and then knock the top shell sideways to open. Lay the top shell flat in front of the console and unscrew the LED board. Be sure not to lose the printer bezel and cutter button as they are held in loosely.
To access the IO board:
- Unplug the two rearmost IO cables from the main board (CB and CC). The cables cannot be unplugged at the IO board end.
- Unscrew the printer module's lower 4 screws and lift it towards the front of the console, be careful with the ribbon cable.
- Unscrew the 4 screws holding the shield and IO board down
- Remove the shield and slide the board out towards the front.
To access the main board:
- Remove the black eject lever by unhooking the spring, unscrewing the right end clamp, angling upwards and sliding to the right.
- Unplug all cables from the right edge of the main board.
- Unscrew the grounding wire from the printer module.
- Unscrew the 6 screws holding the shield and main board down, and the 2 screws on the cartridge connector.
- Remove the shield and lift the board up and towards the rear.
Ensure the power switch, printer bezel and cutter button are properly aligned when reassembling. Can be reassembled without shields and eject lever for testing.
