Eagle Fish Mark 320 Screen

Eagle FishMark 320 is a handheld fish‑finder with a 5‑inch 320×240 pixel LCD that displays sonar returns and depth data. Common failure modes include a blank or flickering screen caused by a dead backlight LED, failed LCD controller IC, broken power‑to‑display wiring, or firmware corruption. First‑check diagnostics: verify the unit’s main power supply voltage (12 V DC) and ensure the display’s VCC and ground traces are intact; inspect the backlight LED for continuity and correct current limiting resistor values; review any error codes in the menu that indicate a screen fault or reset the device to factory firmware if available.[oss-gpt-20b]
