Yamaha RX-V371 Repair and Test

#electronics #repair

I purchased a faulty Yamaha RX-V371 Home Theatre Receiver. Will I be able to fix it?

[SalemTechsperts]

This is awesome. The first thing I ever fixed was a Sony receiver from 1997 that my father put on the sidewalk because it wouldn't turn on anymore. This was 2005. I thought to myself, "I wonder what makes this thing work" So I brought it up stairs to take apart. Turns out the plastic power button was just misaligned and wasn't pressing the switch to turn it on. That receiver worked until 2015. Now seeing receiver's repaired always brings a smile to my face.

Part of this video did help me : system stopped working abruptly ; too much heat this summer season ? Finally I followed this advice : pull the main plug - then plug in again = system works again ! Thank you.

I bought the same amp used, with the same faulty cap, and did the same repair, around when you released this video...but only now did YouTube recommend this video to me! :P

Really liked this video. I spotted that bulged cap early on, but you went through every option which is a great learning experience to detect WHY this power was not working to spec. Some caps look bad but aren't some look good and are bad. I am NOT good at this but try anyway, haha and would like to learn. I think a couple thousand$ in meters and tools and learning to read schematics (which you actually gave a quick tutorial here) and getting service manuals (for free too ;-) would get me on that path, maybe. But your Video made the detection process so nicely transparent and logical. The camera work with very useful macro and the attention to show the real part associated with the schematic was lovely. Cherry on top was your backing music was ancillary and nicely quite low in the mix so didn't interfere at all with your narration.

Great repair! I can tell you’re passionate about what you do!

This was amazing and now I have no option but to sub. Thanks for taking us with you!

Only just stumbled across this video and throughly enjoyed it! Brought back memories of the past!

First of all, thank you very much. so it couldn't be explained so well. You are like a real teacher. I met you for the first time with this video, but I am very pleased. You explained very well. Thank you so much. i have the same problem and i will try all the steps in the morning

Great job. Me and my friend follow your video from the beginning and we have resolved the issue due to you hard work… thanks a lot

Excellent work. See, a proper technician doesn't just fire the parts cannon hoping for a lucky hit!

[Uriel-vfhp]

It was not necessary all testing however results very useful to know how to test CPU and signals. Good job.

Thank you for sharing this! Saved our RX-V371 going into diag modus..

I feel like a have taken a trip from Paris to Madrid via Los Angeles. However it was the educational route, and I wasn't that much in a hurry anyway 😊. I like the approach you take on fixing electronics

[solosailorsv]

Another in-depth and insightful set of techniques !
I usually start with a Sniff-Test for that classic fried electronics aroma, a slow visual (as I figure out the labels & circuits), and a needle probe to check for loose/un-soldered pins.... THEN get TECHIE !! LOL

Thank you, same receiver, same problem, same fix. I had no info on the reset mode.

[WestCoastDP]

Good job on the video. For years Onkyo had bad HDMI boards. Many are in the trash. Seems the Texas Instruments DPS chip often failed because of heat, etc. I think in the last 5 years, those problems have gone away. Hopefully.

Thank you sir, I done my work when I saw your vlog

[andrejfx]

Great repair. All that probing and diagnosting, and you knew at the start that is faulty cap

When the sinewave notches just a little bit that's about 1% THD. When clipped off enough like you saw, that should be around 3%. Helpful to quickly visually estimate output power. Solid state amps are usually characterized at 1% and tube amps at 3%. To be more precise we need the FFT analysis.

quiet easy fault, but your explanaitions are great. very entertaining and informative! hold it up
