Near & under IC Q710
2.Failed componet IC Q710 part # LC372100PT
IF you disconnet CKT board NCDG-6575
you will get audio on speaker B left & right CH only
SOLUTION have CKT board NCDG-6575 Repaired or REPLACED
SOURCE: receiver does not power on. standby not on either
The standby light should be on. If it is not, then check the main fuse. WIth the unit unplugged, remmove hte top cover and check the fuse by the line cord. If that is ok, then you will need to check the primary winding on the standby transformer. That transformer has a thermal fuse internally located and that sometimes gets blown due to a power surge. If you do not have the equipment to test this, get a detailed estimate from a local servicer. The standby transformer usually costs arounf $25 or so.

SOURCE: I turn my Onkyo TX-SR600 receiver on. After a few
The most common problem found on FixYa for Audio Video
Receiver's is:
My receiver say's "Protect" or turns on then off.
What's wrong? Seven times out of ten it is a shorted speaker or speaker wire.
To determine your exact problem, the first step is to disconnect all
speaker wires "at your receiver" Next: Turn the receiver back on. If
your receiver still says "protect" or turns off, it needs to be
serviced. If your receiver stays on; reconnect your speakers one at a
time and power back up after
each speaker. You may find that after reconnecting all speaker wires it
works! Most commonly the small braids of wire from the + to the - have
touched and have caused the problem. In some instances, you noticed the
problem only when turning the volume up. either way, make sure the
exposed wires to your receiver are no longer than 1/2" long and are completely
under the screw down terminal or slide in. When you've found the wire
or speaker with the problem, your receiver will go back into "protect"
At this point, disconnect the wire from the speaker at the speaker that
may be causing the problem then test again.* Note* Make sure speaker
wires do Not touch each other as this Will cause a short! If you turn
the receiver back on and it stays on, you now know the problem is in
your speaker itself. To test your speaker, you will need a multimeter.
Set it to ohms resistance and touch the speaker terminals, if there is a
short internally the meter will read "1......" If it's an analog meter,
it will peg to the right. There's your problem. Now, within any speaker
there are quite a few possibilities as to what could be causing the
problem. Most common is a blown coil and the speaker needs to be
replaced. Some speakers have internal crossovers (usually floor standing speakers)
and may have a shorted or burnt board (usually very visible brown burn
marks on the board) and can possibly be repaired if your handy with a
soldering iron. Now, if you disconnect the speaker wire at the speaker
and it still says "protect" Check your wire for the obvious cut or nail thru
the wire if possible. If your system has wiring that runs
behind walls, you may need to use your meter again. Disconnect the wire
at both ends, keep the ends separated, put your meter on ohms resistance
and touch probes to the + and - wires at one side. If the meter pegs to
the right or reads "1...." the wire is shorted and needs to be replaced
or repaired at the short. Hope this helps.
SOURCE: onkyo tx-sr507. was listening to music and
standby light flashing means that it has had a thermal meltdown given that the onkyo can not be that old i would contact onkyo support because our model should be under factory warranty
Testimonial: "Thanks for your help. I'll try Onkyo as you suggest. "
