The power went out, and I lost all of the programming settings on my Onkyo TX-DS898. Is there a battery that I need to replace?
THEY USE A MEMORY CAP.ITS LOCATED ON THE MAIN PCB ASSEMBLY, REF. C7701 ONKYO PART NUMBER IS 3000078/ WITH THE UNIT TURNED OFF MEASURE THE VOLTAGE YOU SHOULD HAVE APPROX 5V IF NOT THE CAP IS BAD. ALSO MEASURE WITH UNIT ON AND YOU SHOULD ALSO MEASURE 5 V IF NOT THEN THE SUPPLY VOLTAGE GOING TO THE CAP IS BAD.
