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?

Re:
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.

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.
Most likely, you have DC Offset(a bad amplifier). The unit is shutting down to protect your speaker system, as well as protect the unit from any further damage. If you require more assistance, or would like to inquire about repairing your Onkyo, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.
Usually Sony and LG Blinking Codes are the same. Here is what I have.
Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
One blink - not used for the self-diagnosis
Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit,
Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. In addition, unit could be in IK blanking, try turning up screen slightly.
Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.
Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).
Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.
If you include how many times the standby light flashes, that will give a fault location. Not to worry, here is a list. Hope this helps.
Unit is dead, No blinks
- Problem in the standby power section. Might check fuse, R607,
Q601, IC601, R612 and VDR601 (should show open).
Continuous blink once a
second, no pausing - No reply from the jungle IC301 (data
bus is busy, shorted to ground, or held high), IK video path is
defective.
One blink - not
used for the self-diagnosis
Two
blinks - B+ over current protection (OCP), unit goes to the
standby mode then displays the 2 blink fault. Could be a short in
the power
supply of any of the circuits.
Three blinks - B+
over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
Four blinks - No
vertical Deflection (V STOP), Screen goes to a single horizontal
line then the video signal muted. Check IC1509, Q1505
Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen slightly.
Six blinks - No
Horizontal (H STOP), no raster, goes to the blinking self-diagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.
Seven blinks - High voltage shutdown. The
high voltage has exceeded 33k and the unit goes immediately into
safety shutdown. Check power supply regulation and horizontal
circuits.
Eight blinks - Problem with
the audio (AUDIO), unit goes to standby and blinks the
self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some
projection models of Sony TV sets, this code means that T8005
(flyback
transformer), or the associative
components in the high voltage circuits are defective on the D
board.
Nine blinks - Replace D 6116 and D 6301 on
the "G" board, do not resolder as this will fix the
problem temporary. Or Panel Module Error or Thermal Error. If it is
intermittent 9 blinks, meaning sometimes the TV comes on and other
times you get flashing, then change the switching regulator on the
"G" board or check connections. Make sure the regulator is
-12 or -13 (negitive).
Ten blinks - Check Q8014 and Q8013 for
shorts, leakage, or bad solder connections on the " D"
board. If the transistors are bad, check R8051 and IC8005, also on
the "D" board.
The best way to fully isolate the fault is to disconnect all the speaker wires, and verify that there are no strands of wire shorting between the speaker terminals on the rear of the unit.
Turn the volume all the way down, full CCW, and if it goes into shut down with theSTBY light blinking then there is a fault in one of the amplifier's.
Thank you for usingFixya, and if I can be of further assistance please ask.
How many times is the red light flashing? The number of times the red led blinks means---
Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.

Please do rate this solution as FixYa and revert for further assistance.
i had the same problem to, i replaced the thermal fuse and everything was back to normal. Be careful if you are a gamer because both times this has happened i was playing my xbox
When it is on, does any audio come out of the speakers? If so, you may have a problem in the protection circuits. If no audio is heard, I would first check the speaker wires to make sure there are no strands shorting across the terminals, and that you have the it selected to output audio to the speakers -- Now also be sure to check the various inputs, for instance if it has a FM receiver, select that and see if any audio comes out then as well. I don't know what the cable guy could do other than knock loose a wire or change connections on you.
same problem. went out all at once. fuse not blown.
