I turn it on and within seconds it shuts itself off. what is up with this? model number htr 5790. it has been working flawlessless until today. nothing touched or changed.

make sure it is plugged up good and there is no dust in the ports and if that dont work you may need new parts for it . is it a radio or a vcr?

Try hooking up the Spkrs sometimes if there is no load the override will shut the unit down so things don't blow.

That proves the audio output stage is shorted on or two channels. It will need to be checked out to assess the situation.

Hi,
On the back of the Receiver plenty of "RCA inputs" ..you can use any of it except
"Phone /turntable" input and than select it from control knob the relevant input..
Take care and pls remember to rate me..
Thanks

The remote for your unit is the RAV-238. You can purchase a replacement here:

there is a post to this already about checking your voltage inside the unit on the back right hand side and how that is done. my guess is your system is set up with all your other devices hooked into one wall outlet and you overloaded it. Or maybe used a ext amplifier to increase your wattage. IF you try out holding down the ABCD method as described and press input? it may overide the factory setting when the unit experience any type of power malfunction.

Was there any source playing through the amp when your kid turned on the system?mabye the cd or dvd.If so the speakers may be blowen,to find out put a finger each side of the dome on the bass driver and press gentley,if you hear a rough sound a little like sandpaper or if the cone is stuck you have blowen sprakers,if not let the amp stay off for a couple of hours it should reset.Ps system lock is in your amp menu at the end of the setup list,but this is to lock your settings.
A good habit to get into is to turn system to mimamum when not in use.
hope this helps.

Hi,


Yes, you would need an iPod to RCA Cable that will connect to your iPod and to the RCA Auxilliary input of the Yamaha HTR-5790 7.1 Channels Receiver. Similar to a Cygnett Groove Transit - MP3 Phone to RCA Stereo Cable or an iPod to RCA Retractable Cable.


Good luck and kind regards.

Took my Yamaha HTR 5790 to a repair shop for an estimate to repair. Cost me $50 for estimate to be applied to repair. It needed two circuit boards replaced at a cost of $390.00.

 

SOLUTION... they kept my $50 and I bought a new AV Receiver that WAS NOT a Yamaha.

 

WOW this worked.. Hold down the ABCDE and the preset tuning right arrow and then hit power.. It puts it into a diagnostic mode, but it stays on.. I just rerouted my video to not use the receiver  and the audio works perfectly now.
