Fastest way to test is to disconnect all speakers and turn up the vol. If it clips it needs service, then re-connect 8ohm speakers one by one and test until you find the speaker or channel that shorts. Then take that same speaker and hook it up to another channel and test, if it shorts, you know now it is either the speaker or the wire. Now, use a new piece of speaker wire from the same channel that caused it to short, replace the old and test. If it shorts, you've got a problem with the speaker. If your handy with a multimeter, check the resistance at the speaker and you will have your answer. If you are not familliar with a multimeter, just hook up a different speaker where the bad one is and test. It's just process of elimination. Hope this helps

SOURCE: VSX-D608 Overload and shutdown
Overload is displayed when the amp draw is excessive, and can be caused by different faults.
when Overload is detected, the protection circuit will shut down the unit to prevent further damage.
The first thing to try is hard reset. Shut down the unit for about one hour to drain power completely.
This can fix minor problems that can cause overload, for example electrostatic charge accumulation on internal capacitors.
If that does not fix the problem, then you must find the fault.
Overload can be caused by shorted speakers, wrong impedance speakers, or by a contact on speakers wiring.
Check speakers connection and test different speakers with 6, or better 8 Ohms impedance.
Another test can be done by unplugging all speakers, and reconnecting and testing them one at a time, at a very low volume.
No more than two 4 Ohms speakers can be connected to the unit, or you will get overload.
If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.
In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

blinks in the display, then the power automatically switches off.
• Something is obstructing the fan. Remove the obstruction and try switching the receiver back on. If the
fan is still not working, or you can't remove the object, unplug the receiver from the wall and call a Pioneer
authorized independent service company.
• The fan is malfunctioning. Unplug the receiver from the wall and call a Pioneer authorized independent
Check for dust balls in and around it. Disconenct power before exploring inside.
