Aiwa | SE211K | St/by only | R617 high (replace with 390K 1/4W) - located behind LOPTX.This causes the micro-controller to shut the set down and store this condition in the EEPROM. You can either replace the EEPROM with the correct one from Aiwa (which then requires setting up with a special handset), or use an EEPROM programmer to reset the values. There are two values that require resetting:
$0139 should be $00 ($2F when faulty)
$013C should be $00 ($33 when faulty)
