Query: Work for awhile, now it is dead

Worked for a few months, then started making a popping noise when not fed by the receiver, then it simply stopped working and only makes popping noise. Probably same problem others reported. $200 to waste since it can't be repaired and Infinity refuses to fix it. What a custimer focus they have. Never will buy from them again.
