The Peritek Corporation C7‑21056‑1.2‑A (AC7‑00712‑21058) is an industrial graphics/display controller board used in multi‑color multiplexors and digital signage systems. Common failures on this model include loss of video output, intermittent signal dropouts, and power‑rail over‑voltage or brown‑out conditions that trigger a “no display” fault. First‑check diagnostics should verify the 12 V/5 V supply rails with an oscilloscope for ripple and spikes, inspect all solder joints and connectors on the board for cold spots or corrosion, and review any diagnostic LEDs or serial error logs for code indications of driver or firmware corruption.[oss-gpt-20b] |
