HTR-5790 shut off problem

After working trouble free for two years, it now shuts itself off after about 10 seconds. I've unplugged it as suggested by the manual, but no change. I've not changed any connections and have had no power surges or lightning that I know of.

    My problem is similar but I was playing a dvd at a very loud level and saw a spark come out of the back of the unit. The circuit protection kicked in and shut the unit down, but now it clicks on for five seconds and shuts itself off. I bought this unit in Feb of 2005 and this is the second time this has happened. The first time it was covered under warranty so I tok it back to Best Buy and they fixed it for free. This time it's my dime. I took it to a reputable repair shop in this area and they said it was an amp that fried and replaced it. It worked well for several hours but as he powered down the circuit protection kicked in again and now have the same problem. He wants to cut his losses and return the unit. I love the sound that it has but I don't want to more into it than it's worth. Any ideas? Thanks

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.

This problem appears to be remote related. When I removed all the batteries out of the remote control, I powered my 5790 back on. The unit stayed on for the rest of the night. My guess is, the remote is somehow emitting the signal to to go back to stand-by. This could possibly be due to the batteries getting weak. Or the remote could have some other problems.

Older-model Toshiba TV shuts off by itself

There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

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

Thye amp has been idle and unplugged for over a year. Main power is switched on, when hitting power on the remote the amp starts for about 2 seconds then shuts off

These have two issues that I always check. Check and see if your regulated voltages are all coming up . With thecover off go to the right side ,the side away from the power in cord, and check the coonector where you will see several different voltages listed. Make sure you are getting strong readings for the 12volt and 5 volt lines. Don't worry about the 3.3 volt line. I don't see that fail much. Other issue are capacitors in output circuit starting to fail. Vallues like 47uf are common. Larry's Electronics.

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.

Shutting off before the safety relay clicks means there is a problem with one or more audio output channels. Time to see a service center. There is little that can be done without a tech...

My Yamaha HTR 5920 Amplifier

1-first try to keep good ventilation around it and confirm that the air flow in and out is completely free from any blocking thing.
2-clean it by air blower.
3-if you use remote control to power it keep it far away and all other remotes also.
4-disconnect all your speakers---- and try to test the amp one by one.until you find the bad one and change it-----if all above not working you must send it to service center near you.

Yamaha htr-5790 no sound

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.

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.

Powers on for just 5 seconds then off

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.
