Question about Onkyo Tx-sr607 7.2-channel A/v Surround Home Theater Receiver black
Power surge shorted out my unit. Any repair solutions?
Although power surge can trigger activations of protection circuits,
there are at times, damage is done before it is activated.
• Check first for low power supply regulators,
then check for possible output stage failure.
let me know if you need further assistance!

Try pulling the plug out of the wall for 5 min or more,give the unit a chance to reset.Hopefully you didn't get a power surge that might have blown the protection circuits.

I am experiencing issues like this although with a VCR connected with analog video. I added a BluRay DVD player and all of a sudden I lost my video upconversion from my VCR. I am going to try to reset the receiver to see if this fixes the problem. If not, I don't think it is the receiver issue, I think it may be the fact that enorder for video to pass through HDMI, allot of criteria needs to be met. Certain Handshakes need to happen, especially with the HDCP issues. Most likely I will connect a separate video cable to my Plasma and use a secondary input on the Plasma for the VCR signal. You may want to purchase the Component Video adapter for the wii system as this will provide you with at least 480p and your receiver should not have an issue passing the signal over the HDMI output. Good luck and give me an update.

So perhaps it's a source sound issue. THAT would best be investigated at the Dish receiver. Consider it's audio settings and how it interfaces with the Onkyo.

Testimonial: "I greatly appreciate the help. Went through the audio settings in the Dish and this helped the issue."
SOURCE: Onkyo TX-SR607 keeps turning off
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.

Look for a friend that can perform the steps below.
I'm assuming that your unit is dead set without an standby LED
light and your outlet is live.1.Power cord - check the cord it might be opened (no
continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse-
sometimes the fuse fail because of the power
surge, replacing with new one will cure the problem, If this is the case I
would advice you to use surge protector/AVR (Automatic Voltage Regulator).
However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the
linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and
still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact , don't attempt to touch anything
because there some fatalcomponents
stored electricity enough to hurt you with a simple mistake only. I would
advice you to look for a
professional to troubleshoot
the power supply. If you want to repair it yourself make sure that you have
necessary tools and test
instrument. First check bad solder joints(re-solder all
cold solder), leaky
electrolytic capacitor(sometimes it has bulged at the top but not all, you better
have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat
sink), open fusible resistor (caused by shorted regulator
Transistor/IC), shorted zener
You may also replace the power supply board, try online like
ebay.com and shojimmy.com. Just type the model no. of your unit to the search engine and the available parts will be display.
Also check if your unit is under warranty before opening the back
panel, it will void the warranty. Avail it because the manufacturer of your
unit will fix it for free or a little charge only.
Hope I helped you.
Have a nice day!
Thanks for using fixya.
