Question about Onkyo TX-SR500 Receiver
Unit shuts off immediately after turning on. Standby light blinks. No wires or cables attached. The unit is only plugged into the AC. Guess it's a fuse. No warranty. So how do I go about replacing the fuse?
Hmm. Tricky problem. It could be the main fuse blown and the standby power suply is only working. Worts case senerio is that one of your amp is faulty and the unit is in protection mode. If the fuse is dead then you are lucky, just get the cover open, remove the power before hand, and do a little search, Most of the time it will be in a glass tube ( glass cartridge type) rated at 250VAC with a nominal of around 5 to 7 amps rated current. U can check it with DMM in a continuity mode. If fuce blown replace with the same rating and it has to be slow blow type. Cheers

In some cases, the STANDBY indicator may blink slowly, twice per second. In this case, turn off the unit, unplug the power cord, and check the following points.
Make sure the speaker cables are not reversed and connected to the wrong sides (+ and -) on the unit.
Make sure the speaker cables connected to the unit are not shorted. (Check both the unit end and the speaker end.)
Make sure the volume does not exceed the level that the unit is capable of producing.
When using the unit in a rack or other enclosed space, heat may build up inside the unit and cause a fire. When installing the unit, be sure to leave suffi cient space between the top, back and both sides of the unit and walls or other AV components to prevent the internal temperature from rising.
After checking these points, plug in the power cord and use the remote controller to turn on the unit. Turn down the volume before resuming playback. Confirm that there are no problems with the speaker connections and playback performance.
If this symptom recurs, request service at your nearest service center.
In rare instances, the unit may enter standby mode and the STANDBY indicator may blink rapidly, 8 times per second. In this case, unplug the power cord and request service at your nearest service center.
