Yamaha receiver stuck in standby mode

Did you try leaving it unplugged for awhile? What model is it?

yup unplugged for a while
model is rs202

i looked up the model and standby in google and someone said to try holding down the speakers A and bass+ buttons together and then push power, but that combo never worked for me

Not going to say it works for a Yamaha but my Denon was doing weird things (switching itself to intenet radio from any other input) so I pressed and held down the power button until is restared (said so on the display).

Or try this

Yamaha RX-XXX AV receiver’s protection circuity is activated when there is fluctuation in power 3v consecutive times. This protection mode disables the capability to turn on the device. To disable this hold Info + Tone Control + Straight for at least five seconds, while still holding, press the Power button. Manually reboot the AVR for normal operation. Press Straight + Power button to go to Advanced Mode.

I would disconnect the speakers and try again. Sometimes, the defective speakers or the cabling might cause a short or an overload in the amplifier section (due to the short) causing everything to shut down.

thanks, i looked for those buttons in your link, but they are not supported on my model (rs202)

there are no speakers or anything hooked up - i thought there might be something lodged like a wire strand from one of the speakers, but can't see anything in any of the holes

shook the unit and don't hear any rattling either

got me stumped

it's out of warranty - i will start probing with my multimeter and have basic soldering skills, but anyone know what would an electronics/radio shop would charge to fix this?

You may be better off doing some probing first. However, I would be careful in there as there are a couple of big capacitors within amplifiers that store a lot of power so I would start by leaving the unit unplugged day or so and then start probing for continuity of any fuses and the like first. Then I would move on to verifying the electrolytic capacitors are working before doing any live power test.

Few years ago I had similar problem with Yamaha , don't remember the model - after googling decided to get rid of it as apparently it was some board $ going wonky in those models

is there a button combo to do a factory reset.

I press the LEFT preset and BASS+ buttons and the power buttons at the same time then release. This will reset your unit.

Thanks wineman...fixed my r-s201

I can hear the relay clicking on when I hit power, but then the standby light stays on and the receiver never turns fully on.

I had the exactly same problem with my 25 y.o. HK AVR100 amp.
It was working fine, until a few weeks ago it wouldn't switch from stand-by mode to power on.
After reading service manuals, resetting, etc., I decided to open it.
Right away on the power board I noticed a blown fuse.
Obviously, it got blown for a reason. But I was too lazy to troubleshoot it.
I replaced the fuse with higher amperage, plugged it in, and voila.
The magic smoke escaped, and now I'm looking for the pair of powered book shelf speakers.

Be very careful with this approach -- there's a reason that the original fuse blew, and also a reason why it was rated the way it was (and not higher). By replacing the fuse with a higher-rated one, you are giving the underlying issue a chance to get worse and / or cause more damage elsewhere.

The magic smoke that he mentioned is what makes electronic components work. If the smoke is allowed to escape the components no longer work.

Yep, I understand that lingo. Just saying that replacing, e.g., a 1 A fuse with a 2 A fuse might stuff the magic smoke back into the stereo temporarily, but release a whole lot more in the long run.

Suspect possible bad capacitor or shorted resistor - any ideas how to get this to reset and diagnose?

Thanks!

I had the same experience with my yamaha amplifier. I found the big electrolytic capacitor (the one after the bridge rectifier) bad. Open the box and check for bad capacitors first.
