Good day.
Looking to repair my Alpine car radio model XQD101390LNF. It is not turning on; BAT+12V and IGN+12V are present at the input connector. Power switch tact button confirmed healthy. Made in ~2000; Japan. Cannot find its schematic. Thanks.
 

Painful troubleshooting, desoldered multiple pin connector to probe underneath, repaired.
Found corroded-open circuit bad design tiny hidden via in the main +12V supply trace. Inserted wire and soldered to top/bottom traces. Done. Works. Happy.
