Calrad Electronics 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.

Calrad Electronics is a long-established, family-owned U.S. electronics manufacturer and distributor serving the audio/video, connectivity, installation, and electronic-components markets. The company traces its history to the postwar electronics industry and says it has been under the same family ownership for more than 60 years. Its product portfolio includes HDMI and analog/digital AV cables, connectors and adapters, AV converters, switchers, distribution amplifiers and extenders, IR control products, USB/network hardware, power products, wall plates, security-related accessories, and assorted electronic components. Calrad also performs custom assemblies and modifications for OEM customers. It is particularly associated with AV interconnect, signal-distribution, and installation hardware, offering a broad catalog for electronics installers, integrators, distributors, and OEM customers. Calrad's U.S. operation is based in Los Angeles, while its product supply/manufacturing network is concentrated in Asia.

2 Most Seen Failures:

No Video / No Signal Output

Calrad HDMI extenders, converters, splitters, and distribution hardware may produce no usable video at the destination. Common associated conditions include power loss, cabling problems, incompatible source/display formats, or failed signal-processing hardware.

Intermittent or Degraded Video

Video outputs may exhibit noise, spots, distortion, dropouts, or unstable images even though the source signal is good. This can affect individual amplified outputs while a loop-through output continues to operate normally.

Power Supply / No-Power Failure

Externally powered Calrad hardware can become completely nonfunctional or intermittent when its AC/DC adapter, DC connection, or internal power circuitry fails. Loss of adequate power can also present as a signal failure rather than an obviously dead unit.

HDMI Handshake / Compatibility Failure

HDMI distribution and extension hardware may fail to establish a usable connection between particular sources and displays. Symptoms include a blank screen, intermittent picture, or equipment that works in one source/display combination but not another.

IR Repeater Not Controlling Equipment

IR repeater systems can show power yet fail to control the connected AV component. Receiver/emitter compatibility, emitter type or placement, wiring, and unsupported IR behavior can produce this symptom.

Individual Output Port Failure

One or more outputs on a splitter or distribution amplifier can stop producing a clean signal while another output or loop-through remains functional. This points toward a failure localized to an output channel, connector, or amplification stage.

Audio Converter Produces No Audio

Digital-to-analog converter hardware can power on but deliver no usable analog audio. Input selection, unsupported or incorrectly negotiated digital audio formats, source configuration, cabling, or converter circuitry can be responsible.

Cat5/Cat6 Extender Link Failure

Calrad AV extenders can fail to pass a signal between transmitter and receiver when required cable runs, paired connections, or power requirements are not satisfied. A failed transmitter, receiver, power source, or network cable can produce the same apparent no-link condition.

Connector / Cable Intermittency

Calrad cable, adapter, and connector-based products can develop intermittent or lost continuity at plugs, jacks, terminations, or cable conductors. The resulting symptom can appear as intermittent audio/video, signal degradation, or complete loss of connectivity.

  1. 1 Repairs are performed on a best-effort basis. Acme Revival utilizes a network of sophisticated technicians and engineers with diverse service offerings; despite this, factors that influence the repair outcome may ultimately prove unsuccessful. Acme Revival makes no claim that it can, guarantee a repair before your device is sent in for diagnostic evaluation; even then, repair and diagnostic work are not mutually exclusive. Despite well-intentioned quoting, repairs may still prove unsuccessful.
