Questions and answers
Display on, but not working means no volume
The Casio SK-1 turns on but has no sound output. The user is using a working 7.5V power supply with a negative center. Measurements were taken from transistors T3, T7, and T8. The issue could be in the audio amplification circuit, power distribution, or a faulty connection. Checking the speaker, headphone jack, and components in the signal path may help identify the problem.
