Common Aucma Error Codes & Fixes

LED Blink Codes (Red Light Patterns at Bottom)

  1. 1 Blink
    Power Supply Fault: Missing 5V standby.
    Fix: Replace 4007 diodes or STR-X6059 IC (KSh 1,500). 80% resolution.

  2. 2 Blinks
    No +12V Supply: Main power rail failure.
    Fix: Recheck X capacitor (105/400V), replace power board (KSh 2,500).

  3. 3 Blinks
    Audio IC Protection: TDA or R2A amplifier short.
    Fix: Lift audio IC pins, bypass with resistors, or swap mainboard (KSh 4,000).

  4. 4 Blinks
    Backlight Failure: LED strips open circuit.
    Fix: Series LED tester confirms dead strings—replace strips (KSh 3,500, 32″).

  5. 5 Blinks
    T-Con Board Error: LVDS cable or timing controller fault.
    Fix: Reseat ribbon cables, swap T-Con (KSh 2,000). Common on 40″ panels.

  6. 6 Blinks
    DDC Communication: EEPROM read failure.
    Fix: Reflash mainboard firmware via USB (Menu 1147 service code).

  7. 7 Blinks
    Horizontal Output: Jungle IC protection (CRT legacy).
    Fix: Check 8V line capacitors, replace TDA11105PS (rare).

  8. Continuous Blinks
    Overcurrent Protection: Short across 24V rail.
    Fix: Component-level trace—usually power FETs or electrolytic caps.

On-Screen Error Codes (Service Menu Accessible)

  1. Error 101
    Network Timeout: Wi-Fi module disconnect.
    Fix: Service Menu (Menu 1147) → Reset Network Adapter.

  2. Error 202
    No HDMI Signal: EDID handshake failure.
    Fix: HDMI IC reset, port cleaning, firmware update.

  3. Error 301
    HDMI Port Fault: Specific port dead.
    Fix: Bypass HDMI switch IC, direct routing to scaler.

  4. Error 404
    Firmware Corruption: Flash memory error.
    Fix: USB recovery using universal Chinese firmware (FAT32).

  5. Error 501
    Hardware ID Mismatch: Panel/mainboard incompatibility.
    Fix: EEPROM rewrite matching panel timing (Pro-Logic exclusive).
