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.
Centon Electronics, Inc. is a privately held American memory and data-storage manufacturer founded in 1978. The company designs, manufactures, qualifies, and supplies DRAM memory modules, solid-state drives, USB flash drives, SD/microSD/CFexpress memory cards, embedded flash memory, and UFS storage products for consumer, business, system-integrator, and OEM applications. Centon is particularly known for configurable and BOM-controlled memory products, legacy-product support, private-label/custom solutions, and commercial- and industrial-grade storage for applications spanning computers, embedded systems, industrial automation, medical equipment, defense, transportation, surveillance, robotics, and other specialized electronics. Its OEM operation supports custom SPD/timing configurations, extended-temperature products, conformal coating, component traceability, and application-specific testing. Centon states that it has operated in memory and storage for more than 40 years and maintains ISO 9001:2015 and ISO 14001:2015 certifications.
Intermittent or failed DC power connections are extremely common across Celestron computerized mounts, causing resets, erratic slewing, communication errors, or complete loss of power. Common hardware causes include worn power jacks, loose center pins, oxidized contacts, damaged wiring, and failing battery connections.
RA/azimuth or DEC/altitude motor-control electronics can fail and produce "No Response 16" or "No Response 17" errors, loss of an axis, or uncontrolled slewing. Failures may involve motor-driver ICs, power circuitry, damaged connectors, or the motor-control PCB itself.
NexStar and StarSense hand controllers can freeze, remain stuck at "Initializing," display no-response errors, reboot unexpectedly, or fail to communicate with the mount. Faults can originate from the controller electronics, keypad, display, cable, connector, or corrupted controller firmware.
The right-ascension or azimuth axis may stop moving, move intermittently, jerk, or fail to track accurately because of motor, encoder, gearbox, wiring, or motor-driver problems. On computerized mounts this frequently presents as a No Response 16 condition or an axis that stops during a slew.
The declination or altitude axis can become nonresponsive, move erratically, or stop during GoTo operations because of motor, encoder, gearbox, cable, or motor-control faults. Celestron associates loss of communication with this axis with the No Response 17 error.
Damaged, contaminated, loose, or electrically failed HC/AUX ports can prevent the hand controller, StarSense, focus motor, or other accessories from communicating with the mount. Bent contacts, connector corrosion, cracked solder joints, damaged cables, and failed interface circuitry are typical causes.
Excessive backlash, worn gears, loose gear engagement, damaged reduction gears, or deteriorating clutch components can produce delayed axis response, poor GoTo accuracy, tracking errors, slipping, or abnormal mechanical noise. These problems become increasingly noticeable as drive assemblies accumulate wear.
Celestron computerized hardware can become stuck at "Initializing," display BOOT LOADER or "Invalid Package" errors, or lose communication after corrupted or interrupted firmware programming. A successful CFM reflash can recover firmware-only cases, while persistent errors can indicate an underlying controller or communication-board fault.
Celestron Focus Motors can stop responding, fail to be detected, stall, or generate "No Response 18" because of motor, cable, connector, controller, or internal electronics failure. If firmware recovery does not restore communication, Celestron identifies the focus-motor hardware or its cable as likely fault areas.
