MT, doing some checking on the main board, and ive checked pretty much everything, there's a couple parts though I need to know the values of:
R194
R192
R200
R203
Also I am reading 1 ohm across R203, and since I don't have the schematic I don't know if that's what its supposed to be, I can't really identify it visually either.

MT, the RX-V377 is working once again. I could not find a single component on the entire mainboard that was bad, everything is quite spot on. While I had it apart, I decided to call Yamaha today and just see if they'd warranty it. To my surprise the had no problem doing so, but when I went to put the receiver back together so I could send it off, I noticed a very small bridge on the mainboard between 2 components. I cleared the bridge, finished assembling it back together, and it is working beautifully! Thanks for your help MT, I appreciate it yet again!!  |

Well aren't you a lucky dog, lol. Wish they were all that simple. Any idea of what 2 lines or components were bridged?

Well aren't you a lucky dog, lol. Wish they were all that simple. Any idea of what 2 lines or components were bridged? Lucky indeed! I don't remember since I never thought to actually pay attention to the part location #'s, but it was near one of the front channel outputs between a couple SMD parts. It was such a small bridge I didn't even think that was the problem. To my surprise though when I put it back together it worked (and still is working great too!).
Wouldn't have even gotten to that point though if you didn't help get the protection bypass for me, so I really appreciate that!! I wish they were all that easy too. ( I still have those 2 Denon Receivers, the AVR-3808CI and 2808CI that I NEED to get done and have been slackin' on  )
Thanks again MT!!

I't got a mint RX-V377 AVR here that I bought for pretty much nadda, the only thing wrong with it is the typical Yamaha "No power at all" issue. Everything looks like new inside, and the fuse checked out ok and AC is getting to the mainboard.
So I tried the usual "Straight, Tone, Power" reset to get it to come back on but nothing happens at all, there isn't a single relay click out of the unit whatsoever.
As per the user manual (since the service manual is unobtanium) if the AVR has went into protection 3 times or more then power on is disabled, and "To contact your Yamaha Dealer". I'm guessing the previous owner had shotty speaker wire or bad speakers connected to it and that's what caused it to protect itself. I just cannot find anything inside the unit that is damaged, and I'm betting its some sort of reset since that's what the main issue was on a few other Yamahas I bought.
I seek your great wisdom Oh MasterTech lol For RX-V377, simply hold INFO + TONE CONTROL for 5 seconds and while still pressed click POWER (do not hold it). I've just made it and it worked. |

Ok, ignore my last post I got it to come on with the reset code, and it displays DC PRT: 000L and then shuts down. I can turn it on 2 more times after that (for a total of 3 power ons and 3 protection shutdowns) and have to do the reset again to get it to power on. Something in the left channel? Assuming front left? HI, Can you please tel me what is the reset code to release from protection mode |
