If I turn the volume yp over 60 on my Onkyo

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.

over heating your amp with a problem and its going into the protect mode... better stop before it dies for good...$$$ to fix....speakers mismatch or wrong ohm rating for starters bad speaker, bad xover...

Sounds like your receiver is fried. Your best choice is probably to take it to a repair facility, where they can figure out what component failed, or to buy a new receiver.

Onkyo TX SV727 Manual AV Control Receiver HiFi Engine

1) I bought the same Onkyo model from goodwill a couple years ago and it had the same problem. The solution is simple: Get yourself some Deoxit D5. This is a spray that will clean out all the oxidation in the volume pot. To do this you'll need to remove the cover of the receiver. Deoxit can be bought at guitar shops, or if you know a musician they might be willing to do it for you.

2) User manual is available for download, for free. Google "Onkyo tx-906 receiver manual".

Make sure you have the tv volume turned right down as this will cause an echo,also set amp to prologic 2, and set up xover to suit your speakers or go for the THX standard of 80 hrtz and as a rule of thumb set front L,C,R speakers to zero rears to about +4or5 and your sub to -5[ dont know which speakers you have but try setting the subs on board volume to the 10,o,cloak position],also make sure the speakers -,+ are wired the same at the amp and speakers.

Hope this helps.

Does it display any message like "Protect" or something similar? Do you hear a relay click on then off?

Did the amp just not power up one day or did it stop working while you were listening to it? Finally, do you have teenage kids who might have been listening to your receiver and would have "neglected" to tell you that after listening to their music it suddenly stopped working?

It could be an internal fuse but chances are its something that requires a technician to repair (like the output transistors).

The unit is in protect mode. A problem was detected in the final stage of the amp and the unit shuts down to prevent further damage to either the amp or speakers. Check the speaker wires to be sure that they are not crossed anywhere. If with the sepaker wires disconnected, the amp still enters protect mode, the problem is internal to the amp. This is usually defective output transistors. Expect a parts cost between $15-$40.

this could be the pre amp transistor or the power amp that needs replacing
the pre amp transistor is cheap but the power amp is not
if you did not crank it , then it is probably just the transistor that needs replacing

HI check your speaker cables are not touching, also make sure "b" speakers are not on and that all your speakers are 4ohm or higher as this will cause the amp to shut down if they are to low an impedeance,The amp is protecting itself when it shuts down.

hope this helps.
