I have a onyko tx-sr500 Receiver i got a couple yrs ago. I had to send it in to onyko once while it was under warranty. Now i have the problem again and its not covered. I turn it on and it clicks once then it clicks again and the screen pops up and it clicks a third time and it shuts off and this is all in the matter of 3 seconds. So its like 3 quick clicks. I think its a fuse or something maybe im wrong. Can someone please help me fix this problem?
The receiver is drawing too much current as the result of a major fault. The fault could well be failure of an output device.
You now have the same fault as before. There are too possibilities. The first is that the unit has a design flaw. Equipment tends to fail repeatedly in the same way.
The second possibility is that your receiver does not like your speakers. What speakers are you using? These budget receivers don't like low impedance loads and are inclined to blow driving them. Even if your speakers state they are 8 ohm, in practice this does not mean much, as speaker impedance is all over the map with frequency. Try and find out what the minimum impedance of your speakers is.
If your speakers have low impedance and you like them, I would upgrade to amplification that is stable into low impedance loads. My personal view is that units that are not stable into four ohm loads are not very useful.
Unless you have a lot of experience in electronic service and the test equipment to match, you are not going to fix your unit.
