Question about Yamaha HTR-5740 Receiver

Should I just Buy a new one?

Hello I have owned this reciever for about 3 years now. My problem is that the reciever shut off by it self a couple months back after unplugging and plugging back in the reciever continued to work fine. But just the other day the reciever cut of and will not turn back on. I tried unplugging and plugging back in but all I hear is a clicking sound as if the reciever is trying to turn on but will not. Also after a few attempts the clicking sound completely stops.I also disconnected all devices from reciever but no luck. It does not smell as if anything is burnt out. Any help would be greatly appreciated. Thanx in advance.

Re: Should I just Buy a new one?

You have a bad power supply or the audio output circuit has a short in it. You are correct by saying its probably betterv off getting a new unit. Most likly cost you more then a brand new shiny unit would . Good Luck PS Please do not forget to rate this thread

Reciever keeps shutting off!

If your reciever is in a tight enclosed space, than it will overheat and shut down to protect itself. Try to get some ventilation to it by either opening the cabinet door, adding a fan, or pulling it completely out of the enclosed space.

Rx-v795a reciever shuts off after 5 min or more can not hear fan in reciever for cooling.

This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic. 1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

My reciever plays then cuts out

They don't overload from missing speakers. I'm curious, what buggered the one speaker?

Examine all of your speaker wires carefully to be sure no unintended contact is made between them and anything else.

Is "overload" being displayed?

“OVERLOAD” starts flashing on the display.

Speakers are overloaded because of high volume.

1. Press STANDBY/ON on the front panel to turn off the receiver.
2. Stop the playback source.
3. Turn on the receiver again, and adjust the volume.
Speakers are overloaded because of short circuit of speaker terminals.

Press STANDBY/ON on the front panel, then check the speaker wiring.

If “OVERLOAD” does not disappear after turning on the receiver again, unplug the AC power cord, then plug it back in again.
If speaker wiring is not short-circuited, contact your dealer.

I have a KLH 700watt home theater reciever that wont stay on!!

Sounds like it is overheating. Try one or all of the following:

Remove anything that may be stored on top of it. Unblock the vents.

Connect speakers with a higher sensitivity rating.

Move it to an area where it has more airflow around it, ie; not in a closet or cabinet.

Disable any bass-boost and equalization, or tone controls.

Set any crossover settings for any subwoofer you may have connected, to a higher frequency.

Decrease your listening volume.

Receiver shuts off on its own

I have the same receiver and the way to fix is simple. in the main board of this unit there are 5 connectors and they slide into other components like Lego. the issue is the king of material they are made of it's cheap. if you reseat the mainboard it will fix it for a day or two, them it will start again. the easyway is to re seat the board and put a fan inside of the receiver between the transformer and the inside of the amp pointing down about 20 degrees connect the fan to a ajustible voltage adapter and connect it to the outlet in the back of the unit. so it comes on when you turn it on. this voltage adapter is cheap. the adapters people buy for phones and or MP3's at Radio shack or Best buy it goes from 1.5v to 12 volts/ this way you can control how loud the fan is in side the receiver. i find 4.5V does the trick. The connectors on this board start to loose contact with some of the pins when heated. the fan keeps it cool enouth to fix the issue. I fixed manny these ONKYO 804's this will fix it. you just have to do it. the main board is inder the HDMI board in a Vertical position running from one side to almost the Power supply. it has 2 screws also holding it in the inside middle back of the amp. Becarefull with these amps 75 V at 23amp's DC is no joje leave it off for a couple of hours to satart working on it. Good luck.

You really may not have a choice in this matter of buying a new one, Unless you want to invest about what it would cost you to have your unit looked at? There are no parts you can change, as its a solid state unit and all parts are soldered into place and also you have to know how to troubleshoot solid state electronics.. My first guess would be a problem with the power supply.. Its probably one of the switched supplys thats bad. Unless you know how to use a multi-meter and the workings of the soliod state regulator circuits, your gonna have to take this unit in to get an estimate.. Good LUck
