Question about Onkyo HT510 Receiver
SOURCE: blinking standby button
Hi...1st off ...make sure all the speakers are connected at both ends.
2nd..buy a new cat..one that doesnt drool.
If it's still stays in Stdby after checking speakers, It might have blown an internal fuse cause thats where those darn stereo people put them now.

The receiver is going into "protect" mode. This means that a problem has been detected and the unit shut down to prevent further damage. Without seeing the unit and taking some internal measurements, it is difficult to provide a complete solution. Typically, the output transistors fail which can cause this. There are other possibilities too. I would suggest that you get a detailed repair estimate from a local shop. With that information, we may be able to walk you through the actual repair.

If you push the power button and you hear it "click" that means it's getting power. Now, that being said... Couple things to check: first: disconnect all speaker wires at the receiver and attempt to power up, if it does, that's a good sign that your receiver is ok and your problem lies in the speakers or in the speaker wire. If you still can't get it to power up, pop the top of the unit. Most receiver's have 6 or 7 #1 phillips head screws on the sides and rear of the receiver. Pull these off. Look directly at the area where the power cord plugs into the unit (make sure the unit is unpluggged) There is usually a fuse right nearby. If it's a white fuse or gray fuse you may need to do a quick continuity check with a meter to test. If your familliar with meter's, just switch it to continuity/tone. If the fuse is good, you will hear a tone from the meter. If not, there's your problem. If your not sure how to test with a meter, either take it to Radio Shack or similar store, ACE hardware etc. they can test it for you and will generally have replacements in stock. If the fuse is good, your speakers are disconnected and you still have no turn on, your receiver needs to be serviced. If that's the case, whether you service or replace the receiver, get a good "Theater" line conditioning surge!!! like Panamax, Monster, APC, or Furman. A good unit will start around 250. Small price to pay for saving expensive electronics! Hope this helps. If you need further help, just post a comment and I will be glad to help.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the
speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.
