flashing red, orange and white

Bose product name

lifestyle 550 subwoofer




Detailed description of the issue and steps to reproduce

My lifestyle 550 home cinema is 14 months old ( guarantee only 1 year in Mauritius) . On some days the subwoofer light is flashing red, orange and white and sound is not coming from the subwoofer. On some days the subwoofer is in good condition and plays well. I send the Bose subwoofer AM300 to the local supplier. The diagnosis was "it was found that the 48V shows fail which is a hardware problem. we verified that the mainboard and the board need to be replaced". The mainboard price in Mauritius is about $450. My question is if the main board is faulty how can i get sound on some days and on other days the subwoofer does not play?
