Yamaha QY20 Music Sequencer

This is the QY20, the model that started the enduringly popular YAMAHA QY series.

The LCD has been replaced with a separate component, and a conversion module has been installed to display on the replacement LCD. Due to the different display size, the screen appears smaller as shown in the image. On the other hand, it has a backlight, making it easy to see even in dark conditions.
The battery still has charge (indicated as 3.0v in the last image), and the sound is clear, indicating good condition.

[Repairs Performed]
- Replaced LCD with a separate component (as a compatible part could not be obtained).
- Replaced battery terminals due to corrosion from battery leakage.

[Operation Confirmation Details]
- All self-checks on the QY20 are OK (key input, internal memory, voltage, battery, 1kHz output, MIDI, etc.).
- Phone output, Line output, left/right balance, volume, no noise.
- Operation confirmed with both AC adapter and batteries.

The exterior has many scuff marks, and there are noticeable scratches on the transparent part of the LCD (second image).

A final operation check will be performed before shipping. Please understand that if any operational defects are found, the transaction may be canceled or we may discuss shipping after repair.

Although not an original part, a new 9V AC adapter is included so you can use it immediately.
