Question about Onkyo TX-SV535 Receiver

1 Answer


My tuner has started turning itself on multiple times during the night. I will turn it off and a few minutes later it will turn on again. This happens a intermitantly. I made sure that the Sleep function is off. Just started a few months ago. Any ideas?

    Thank you - it must be the power supply. Probably not worth fixing at 11 years old.

    Ladies and gentlemen,

    When I power up the receiver, in the past it clicks and then within about a second full power is initialized. Three weeks ago when I powered it up, it clicked as usual, but then instead of powering up, it just clicked ON/OFF, ON/OFF, ON/OFF, and on it goes without ever powering up.

    There were no lighting storms within the day or two before, and I have a plug-in surge protector, but I know that they aren't foolproof, and in fact, the surge protector is as old as the receiver, so it wouldn't surprise me if it has been useless for who knows how long, however I don't believe I was hit with a power surge.

    I'd like to note that I us the receiver to run the sound output of my digital DVR through my receiver, thus getting 5-1 sound from TV stations supporting it, as well as the FM tuner and CD/DVD player. In addition, I've had no problems with performance degradation of any kind, In fact I've never had a single problem with the reciever; it has performed flawlessly.

    Does anyone have any suggestions and/or comments regarding what my power failure may be caused by and what I can do to correct it?

    In advance, I appreciate any help that anyone can offer.

    PS: I am currently researching for information regarding replacing the AC fuse...

    Ladies and Gentlemen,

    Regarding my post (aug 16, 2008) about my Onkyo TX-SV535 receiver, is there anyone who can provide me with information about changing the AC fuse (I haven't found anything on, fixya, etc.) ?

    FYI, I am a computer guy (MCSE, A+ hardware,software; not bragging, just trying to explain my field of expertise), but I have had no formal training in electronics.

    I feel that I am capable of changing the AC fuse with some direction, although I'm not convinced this my problem, but after changing it I could rule this out as the cause of my power problems.

    Thank you in advance for any help, direction, or comments

My sony has started turning itself off after 20-30 minutes, each time you turn it back on it will turn itself off after a shorter and shorter run time. Leave it over night and it will start the next day...

It might be over heating. If there is a lot of dust
inside of the back of the T.V. you should take it outside and blow it out with an air compressor.

good luck

Turns off after a few seconds

The unit is going in to shutdown. There is a short in the unit. My guess would be the HOT and or Flyback are bad.

The flashibg red light

John, I do not know of a code, but it is a good idea in the design to have several goes at starting a circuit, before completely shutting it down. Oscillators are supposed to self start due to noise generated. Some electronic circuits require a reset pulse to be generated before the start up is allowed. The reset circuit may not be generated if the set is turned on again too soon, so it will stay in standby. This may normally be a few minutes to 30 minutes so it seems something in your set is faulty and could get worse. Try a test run with the back off and clean it out of dust with a long brush to keep it cooler. Make sure little fingers cannot get near it. Look to see if anything is obviously overheating.
