Lowrance LCX-I04c Fishfinder GPS unit has a bad screen unable to find a replacement will send RUR unit back to cust

The Lowrance LCX‑I04c Fishfinder GPS is a handheld navigation and sonar unit whose primary failure in this case is a non‑functional LCD screen that cannot be replaced locally. Common causes for a dead display on this model include a cracked or burned LCD panel, a failed backlight driver, or a broken flex cable/connector between the board and the panel. First‑check diagnostics should verify that the unit receives proper 12 V input from the battery or shore power, inspect the screen connector for corrosion or damage, and test the display with a known good panel or by swapping the LCD module if available. If the backlight circuit is intact but the image remains blank, consider replacing the entire display assembly as the only viable repair path.[oss-gpt-20b] Post Comment
