Yamaha Audio Players & Recorders - Page 6 - Recent Questions, Troubleshooting & Support

Question edited for full 'make model (what is is).Sounds like the aerial antenna is not connected. Check behind the unit and also the connector wherever it goes.

I would get it fixed at a Yamaha Service Centre, as you don't have the test equipment to find which failed component is causing it to shut down and protect itself. The only thing you might try is looking for bulging or split capacitors. That WOULD cause circuit protection, because they are power stores and smoothers.

You've probably already tried this, but...

Disconnect power from the mains, remove lid.

Reseat all the low-power connectors in the unit.

Check the thermister on/near the main transformer.

Check capacitors on or near power supply for obvious anomalies (fattness, leaking, smoked, etc.)

Replace lid and, plug back in, do a rain dance and hope.

Try Factory Reset (Restoring the Factory Programmed Settings). Before doing this,it is recomend that you Backup your files. Go to: FUNCTION - UTILITY, and tab SYSTEM RESET .

Check speaker wires did not short out or the amplifier was not over driven. The usual cause to go into protect mode is a failed power stage.

Question edited for clarity. Question moved from Office Equipment. Did you connect the AM and FM Aerials to the rear of the unit? Page 10 of the manual refers. https://www.manualslib.com/manual/197298/Yamaha-Rx-V4-390.html?page=10#manual

This is directly from the service manual for the R-N402: Hold the left preset button (<) and the bass (+) button and press the power button and then release. The receiver will disable the power protection and turn on in self-diagnostic mode. My device is working correctly now. :)

I had the exact problem with the same model. The way to reset it to the factory default is quite easy (you will lose all previous settings). first , Make sure that it is plugged. Then press on the "info" and the "tone control" at the same time. Keep pressing for a few seconds. you will hear a "clicking" sound and the receiver will turn on.

Yamaha RX-V661 LCD / Front panel. Symptom: when you first turn iton, you can see a VERY little light but after 5 sec, you cannot see it anymoreor for most of us, we started using a flash light. Here is the summary of the solution and I know that it worksbecause I fixed it today 3/16/2011, 30 minutes ago. As many pointed out that there is a"light" 12v - 14v in the back but there is NONE. How do I know? I listened and searched andthere are NONE. The whole LCD in the front is air seal like a light bulb so itis a light bulb already. Also, you mightsee a little burn/gray smoke on the left hand side, don't worry about itbecause if the light comes on, it stills work but not enough power. If the LCDis broken, please don't try by the part and replace it because by the time youread this, the parts and labor cost as much as buying a new one (on eBay andnot Best Buy). Problem: in the middle of the unit near the back near the "surroundsound back", there are 3 capacitor rated at (2 units) 35v 220uf 85'C and(1 unit) 50v 220uf 85'C. What Yamaha did wrong, base on my guess is that theyput the 85'C too close to the heat sink. The heat causes the capacitor to slowly blown that is why you still getyour power to the LCD but not enough. Solution: remove the top, unscrew EVERYTHING in the back and there are about 20 ~ good luck. Forthose that don't have good memory, please take a picture. There are many plugs insidethat you need to unplug before you can remove 1st layer (audio/ video input)2nd player (HDMI and Optical input), the last layer you will see 3 capacitors thatare kind of "blown" up (google "bad capacitors" pictures orvideo). Remove them then replace them, which you can Google this on tube andthey should teach you how. It was very easy for me but then again, please don'ttry to do it if you cannot even change your car oil or build a computer becauseI believe that is the difficulty level. solder iron: $9-$20 get it on eBay or radioshack(2 units) 35v 220uf 105'C and (1unit) 50v 220uf 105'C or what I got was (3 units) 50v 220uf 105'C

I keep the 220uf the same to besafe but increase the voltage and heat to increase the life of the capacitors.

Good luck everyone,

JimmySCW

No sound on yamaha rx-530 stereo fm receiver - Fixya

Feb 13, 2015 - no sound on yamaha rx-530 stereo fm receiver nothing,just no soundcomming out of speakers ... Does your TV have any audio outputs such as RCA perhaps? .... Suddenly no sound is coming from my speakers except for my subwoofer. On certain settings some of the speakers work but not all of them.

The laser that reads the disc's and the lens need to be replaced for your CD player.It cold be that the volume control has worn out and needs to be replaced.

You will need to send it in for repair is my assessment.

Question edited for clarity and spelling. In the link https://www.google.com/search?q=yamaha+rx-v640+factory+reset ..

Not all receivers will support an equalizer. If the receiver has a built in equalizer, another equalizer will not be supported.

Could be a faulty hdmi cable...

Can you turn it on with the switch

Hi Craig, I don't think this is something you can fix yourself, I'd try an electronic service center

You need another remote, just buy one! $23 on Amazon. https://www.google.com/search?q=Yamaha+rx-v379+replacement+remote ..
