Question about Denon AVR-900 Receiver
The 6.3 A fuse on the power board keeps blowing. Any hints on where I should start to look to solve this problem?
First check the output transistors for a short, 9 times out of 10 this is the case. Use a multi-meter on resistance. The transistors will have most of the part # on them, usually you just have to add 2S to the front example an "A1519" on the transistor would be a 2SA1519. If one is found to be bad replace it's complement also even if it checks good (unless you have a transistor checker that will check it for leakage). Good Luck.
