Hello guys, I tried some of the tips you gave, but I'm afraid I'm stuck. I have a Yamaha RX-V677 that turns on - and then right back off again. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. Im experiancing the same isse with Yamaha wxa 50. Come join the discussion about home audio/video, TVs, projectors, screens, receivers, speakers, projects, DIY’s, product reviews, accessories, classifieds, and more! When the unit is in this condition, the standby indicator on the unit blinks if you try to turn on the power....REMEDY: As a safety precaution, capability to turn on the power is disabled. Just wanted to say 'Thank You' to jdhulse74. YAMAHA RX-V357 - HTR-5830. I just purchased a Yahama RX-A1040, hooked everything up, and when I went to turn on the power the red light in front of unit starts blinking. Turn the power on! It might be worthwhile to just connect the FR/FL speakers and one source and see if the AVR initializes properly. So to reset Yamaha A-S1000: Turn balance button full clockwise. How to bypass the protiction issue? Where do I go from here? Hi there, I can tell that this thread is rather old, but so far this seems to be where the "expertise" exists. This thread saved my onions! you need to get the thing powering up to the stage where you can measure things without it blowing up, often replacing the rail fuses with power resistors can help plus disabling protection, another method is light bulb in series with the mains input. JavaScript is disabled. Fast forward a few months and now I am going through the unit. Some Of The Featured Items Are:Sony X950H 65 Inch TV: 4K Ultra HD Smart LED TV with HDR and Alexa Compatibility - 2020 Model,Pixel Dove King Bed by CODDLE,3-Ply Ear Loop Face Masks - 50 count box - Disposable - Face Protection PPE - Breathable & Comfortable Safety Mask Case of 40 boxes,BAK BAKFlip MX4 Hard … Generally you will find it is driving to a rail. Manually reboot the AVR for normal operation. New comments cannot be posted and votes cannot be cast, More posts from the AskElectronics community. After that it's working fine again. This appears to be a resistor used in to bias circuit. It worked on my RX-A2040. First find the service manual. And does not turn on anymore. Then come back with your results. This protection mode disables the capability to " turn on" the device. Interestingly - The two transistors that were shorted and replaced with known good ones, are now failed open. Any solution for a simple guy as me? Without thinking I followed a trick posted by some random guy in the Internet, which, in hindsight, just disabled protection mode. Press question mark to learn the rest of the keyboard shortcuts. It just takes a stray strand of wire that didn't go into the terminal to bend and touch another terminal. I would recommend trying that a few more times. I looked at the little troubleshooting quick reference and it stated that "the protection circuitry has been activated three times consecutively. No other sign whatsoever. If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer. where does it connect to, resistance and power rating ? I found two output transistors that were shorted, replaced them, but cannot find any trace of smoke, arcing, no smells, burn marks, nothing. I've also found that R1148 (that corresponds with the failed output transistors) has failed open. Fast forward a few months and now I am going through the unit. VerticalScope Inc., 111 Peter, Suite 901, Toronto, Ontario, M5V 2H1, Canada. Without thinking I followed a trick posted by some random guy in the Internet, which, in hindsight, just disabled protection mode. The unit should power up. Also I would double check all connections especially the speakers. To disable this: Hold " Info + Tone Control + Straight " for at least five seconds, while still holding, press the " Power " button.

This is an ELECTRONIC ENGINEERING subreddit, covering practical, component-level circuit design and repair questions, electronics theory, electronic components, tools and equipment. I have a Yamaha RX-V677 that turns on - and then right back off again. Amazing answer. Upon plugging back in, press and hold the power button at the same time for 5-10 seconds to force a hard reset. Contact your nearest Yamaha dealer or service center to request repair.". Done! looks like a number to me. For a better experience, please enable JavaScript in your browser before proceeding. Posted by Tech-Opensource at 1:52 PM. Model RX-S601D. A forum community dedicated to home theater owners and enthusiasts. I would assume what you have described in the "remedy" post is the microprocessor reset procedure. By using our Services or clicking I agree, you agree to our use of cookies. Connect power cord to mains and wait 5 seconds or so. Seems to be same problem. For example a common failure area is long tail pairs in the front end, leakage there can cause DC shift throughout due to it throwing out the feedback. When doing this I heard an arc, and saw a puff of smoke. Unplug all cables, check for short-circuits first. Hello all! 2-channel: PSB Imagine T, Music Fidelity M3si, SVS SB-1000, Rega RP1 (Ortofon 5E), Pro-Ject Phono Box, Marantz ND8006. Meaning the two I removed (shorted) were replaced, and the two in the unit now are both open. The receiver is powering now, and then throwing a fault DC PRT:165H, this refers to DC voltage detected on the speakers outputs. Press J to jump to the feed. Yamaha Rx V373 Protection Mode Reset. Double check the speaker connections - you may have shorted the output accidentally. When doing this I heard an arc, and saw a puff of smoke. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode. If outputs short they often take out driver stages and bias networks (diodes usually) as well. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode. Old thread, needs to be locked, or merged with the 1040/2040/3040 thread. How do you know they're failing open and just, you know... open? When I plug it in, the power indicator turns on for a few seconds and then off. there is a thriving market for fake transistors. The unit should power up. Even fixed output stage something caused it to die in the first place, no idea what the amp schematic looks like though. If the unit starts up normally start connecting the speakers one at a time (shutting the power down before connecting each one), until one of the speakers causes the "PROTECTOR" indicator to come on. Connect power cord to mains and wait 5 seconds or so. Be sure that the circuit protection was triggered by a minor problem.
