Repair, Service, and Parts

Casio repair, service, and parts

Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.

Casio Computer Co., Ltd. is a Japanese electronics manufacturer best known globally for its G-SHOCK and other digital/analog watches, calculators, electronic musical instruments, and education-oriented electronics. Timepieces are currently its largest business: FY2026 timepiece sales were ¥184.9B out of ¥276.2B in total company sales. Casio operates a global manufacturing network centered on Yamagata Casio in Japan, which serves as the group's manufacturing “mother factory,” alongside production operations in China and Thailand. Its manufacturing capabilities include watch assembly and components, calculators, electronic dictionaries, musical instruments, and related electronic products.

2 Most Seen Failures:

Battery / Power Failure

Across Casio calculators, G-SHOCK watches, EXILIM cameras, and electronic musical instruments, depleted or aging batteries commonly cause failure to power on, sudden shutdowns, dim displays, stopped watch hands, or disabled functions. Casio documentation repeatedly identifies battery replacement as the corrective action for these symptoms.

Dim, Blank, or Intermittent Display

Casio calculators commonly develop displays that become faint, blank, or difficult to read when battery power deteriorates or available solar illumination is insufficient. In some models, a weak power supply can also cause memory loss or abnormal operation.

Unresponsive Buttons / Keypad

Physical keys, buttons, or touch controls may stop registering or respond intermittently across calculators, watches, and digital pianos. Casio documentation includes troubleshooting for frozen calculator controls, nonresponsive piano touch buttons, and watch controls that cease functioning when power is depleted.

Keyboard Keys Not Producing Sound

Casio Privia and other electronic keyboards frequently exhibit cases where pressing one or more keys produces no sound. Causes documented by Casio include output/headphone conditions and MIDI settings, while key-contact or connection problems can produce failures affecting individual keys.

Power-On / Unexpected Shutdown Failure

Casio cameras, calculators, and musical instruments can fail to start or unexpectedly lose power. Common documented causes include exhausted batteries, improperly installed batteries, aging rechargeable cells, and power-supply issues.

Battery-Related Memory Loss

Some Casio calculators and older Privia digital pianos can lose stored settings or memory when their main, backup, or internal lithium battery becomes depleted. Casio documentation specifically warns that continued operation with weak batteries can corrupt or erase stored data.

Watch Hand Misalignment

Analog-digital Casio and G-SHOCK watches can develop a mismatch between the physical hand positions and the digital time. Casio identifies strong magnetism or physical impact as causes that can knock the hands out of alignment and require hand-position adjustment.

Digital Piano Pedal / Key-Sensing Failure

Casio digital pianos can experience pedals that stop responding or keyboard keys whose velocity or volume sensing becomes inconsistent. Casio's electronic-instrument troubleshooting resources specifically identify nonworking sustain pedals and keys that fail to change or correctly register sound volume.

Projector Overheating / Optical-System Failure

Casio projectors can overheat when dust and dirt accumulate around their intake vents, potentially causing internal-component malfunction. Casio also warns that high temperatures, dust, smoke, and extended continuous operation can shorten the service life of the optical engine and other internal components.
