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.
Decimator Design Pty Ltd is an Australian manufacturer of professional video signal-processing equipment primarily serving broadcast, live production, studio, and professional AV applications. The company designs and manufactures its products in Sydney and specializes in compact SDI/HDMI video converters, cross-converters, scalers, multiviewers, distribution amplifiers, test-pattern generators, and related signal-management hardware. Decimator is particularly known among broadcast engineers and video-production professionals for its portable MD-series converters and DMON multiviewers, which handle conversion, scaling, monitoring, and routing between professional SDI and HDMI video formats. Its products have developed a reputation for combining extensive broadcast-oriented functionality with compact, rugged hardware and relatively cost-effective pricing.
The HDMI input stops detecting otherwise-valid sources even after cables, sources, and settings are eliminated as causes. This is particularly reported on the MD-HX, with some fleet users describing multiple units developing dead HDMI inputs.
The HDMI output stops producing a usable signal while other functions of the converter may continue operating. Reports include early-life HDMI-output failures on 12G-CROSS units and broader reports of HDMI-circuit faults on early units.
The converter fails to power on, powers intermittently, or appears completely dead because its external supply, USB power cable, or associated wiring has failed. Users report worn-out supplies and cable shorts, particularly with older MD-HX-size units.
The SDI input ceases to detect a known-good SDI source despite cable, source, and configuration checks. Long-term users have reported individual MD-HX units eventually losing their SDI input after years of service.
One or more BNC/SDI outputs stop carrying video while other outputs or converter functions continue working. Documented MD-HX cases include failed Output 1 connections that required manufacturer-recommended repair.
The converter and HDMI source fail to negotiate a usable video connection, resulting in “no input,” repeated signal acquisition, or intermittent blackouts. Laptop and USB-C-to-HDMI sources are particularly associated with this behavior, and inserting an EDID emulator or another converter can sometimes restore operation.
Video periodically glitches, blanks, flickers, or loses lock even though a signal is present. Reported causes around Decimator installations include signal-integrity/jitter problems, marginal HDMI connections, incompatible downstream equipment, and conversion or timing interactions.
A unit appears defective because firmware state or routing, scaling, frame-rate, SDI Level A/B, or output-source settings prevent a valid signal from reaching the destination. Firmware reflashing/updating and correcting configuration are repeatedly reported as fixes for apparently failed units.
The computer fails to recognize the converter over USB, preventing control or firmware updates. Troubleshooting guidance identifies faulty USB cables, missing drivers/software, and USB connection problems as recurring causes.
