PLEASE NOTE: The following information is not, nor is it intended to be an official statement from Onkyo Corporation or Onkyo USA. Readers should consider the following as hearsay. If your unit is in need of service, I suggest you call Onkyo USA at 1-201-785-2600 between 9 a.m. and 5 p.m. EST, Monday through Friday.
This afternoon I received a call from Onkyo USA regarding a solution to the 804's audio interference, problem.
Engineers with Onkyo Corporation, Japan have solved the "HUM" problem by adding a new resistor and capacitor to the 804. Sorry, but additional technical information was not available at this time.
So, what is going to happen next?
In accordance with my verbal agreement with Onkyo USA, my 804 will be shipped to Onkyo USA tomorrow via Fedex. Upon its arrival in New Jersey, Onkyo USA Technicians will add the new resistor and capacitor then bench test my unit to determine if the newly found solution is a 100% effective. After successfully passing all QC inspections my 804 will be returned to me ready to get back to work.
Next, this repair process will be repeated on an unspecified number of additional faulty 804 AVR's. Once Onkyo USA has approved both the repair and the overall repair process, it is my belief that owners of faulty 804's will be able to individually arrange for their units to be modified.
Time will tell.
