Question about Audio Players & Recorders
Yamaha RXV1 won't turn on. Every time power button is pressed a clicking sound is heard. So far I have tried unhooking all speakers, and unplugging the unit for 1 minute then plugging back in. It's the same. I was reading about it possibly being a bad/leaking capacitor or possibly a bad amp. I just wanted to find out if anyone on here has some more info than what I've seen thus far. If I use your info and it works I'm happy to send you some cheddar! Thanks!
Hi it sound like bad capacitors on the main power board open it up a se if you have bulging on top or look for leakage

This set is getting old and is in the Archives section of the Yamaha consumer guide area. But, you can still download the owners manual if you need one. If it is going into protection mode even when there are no speakers connected OR when the sound level is very, very low or zero it is not good news. Yes, unplugging the line cord will cause the protection system to reset itself. But, if it shuts itself off again soon after rebooting it is a sign of bad grease in the output stages -- in all probability. Let me explain: The audio output transistors are mounted to a large heatsink which keeps them cool during operation. They are electrically isolated from touching the heatsink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise; as the heat goes up they conduct more current and cause the protection system to activate and shut the set down (in order to avoid damage to the set). That is the most common cause of your symptoms. However, there are several other possibilities, but I give this explanation a 90% probability based on my experience.

You may not be using an active input to test. Try attaching an fm antenna and using the tuner. Sone inputs are set to digial and will not make sound with the analog input. The input selector does turn it on. Saves a step.

SOURCE: Power on problem
Well this helped me find the relay but I found that after i pulled it off the board that it has some corosion around the metal prongs that hold it to the board. Could not get the relay open to do what is posted above , tryed opening it several times. Not sure if you are supposed to open it but could someone let me know. I am scraping around the prongs to get the corosion off hoping it will help but might just replace it alltogether. Further info on how to open the relay to do what is posted would help, I would appreciate any help, plzzzzz! :)

The unit is in what is commonly known as "protect" mode. This means that a problem has been detected in the final output stage of the amp and the outputs are shutdown to prevent further damage to either the receiver or speakers. This should not be a difficult repair for a service shop. Expect a parts cost in the $25-$40 range. Add in the local labor rate for the total repair cost.

Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.
