Yamaha HTR_5990 My Yamaha receiver won't stay on for more than 2 second.

Could be a bad cable or a bad HDMI connection. Does the TV have regular analog cable out that you can try to see if the signal is good?

Sorry Michael, you have a problem in the audio amp section of the receiver and unless you know how to troubleshoot solid state electronics, you will need to have this unit serviced by a pro. Good Luck

You're best bet would be to buy compressed air and blow out all dust and dirt that has made its way inside the receiver. If dust is clogging the fans it will overhead and shut itself off.

according to yamaha website you have 2 hdmi inputs, and one hdmi out on that unit

Depending what happened is the key to solving this, chances are the audio outputs got very hot causing a short which overheated the capacitor, I would inspect and test parts near by to be sure no other part has been compromized. Check all speaker wires for shorts, "a common problem" and take your time when servicing, if unsure! have a professional assess.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

You probably need to take that issue up with the setup of the unnamed device originating the signal.

Is it going into protect mode???
If so, check your speaker connections. Make sure there are no loose copper wires hanging out, and that your splices are clean at both the receiver and the speaker.

The RVA350 comes with this model according to the manual.

Hope this helps
