Imagine. A movie about birds that causes power outages and damage to people's equipment... The Birds? Oops, already a movie called that. Interesting video.
During the hurricane last week my lights went out and on several time - luckily no casualties yet. Those transient spikes can get easily over 6kV when the voltage is coming back. Adding some surge protection devices in front of the internal power line is not the worst idea.
I have more surge protectors around here. The closet with the equipment has 5 surge protector bars by itself. There are another 4 in my office and the house is on a full house protector. I have had surges that trip the breaker on the circuit as all the protectors clamp at the same time and overload the breaker. Usually it's momentary drops that cause the damage. They confuse the regulators on internal smps and that is where the over viktage happens.
And just what do you think I have? I have a big surge protector on the main panel to protect the cars. I put one in after a surge took out my ev charger. I have a square D in the panel and countless surge bars throughout the house. Every device is plugged into one. I have a bunch of single device protectors as well. It's not the surge that damaged equipment. It is a loss of power for perhaps 5 or 10 cycles. This causes voltage to drop on power supply, as power supply is dying the regulator is calling for more power then the interruption ends and cones back, but the power supply has already changed the duty cycle or the frequency of the oscillator to increase the voltage. This causes the viktage to overshoot before the power supply corrects. If the power drops more than that the power supply stops and reboots. It's more prevelant in devices with old capacitors in the power supply. Surges are not really an issue with smps because they will operate between about 100 and 240v no problem.
I'm currently working on a TX-NR626. Interesting to see how the general lay-out is the same, but they crammed even more boards and a big fan in there. 😃
Hi Dave, my first guess on that arkward behaviour was that perhaps the reference voltage for the resistor-strip (buttons and user interface) is bad. Or the reference voltage of the adc on the uC. Sure that is only possible if your device uses that technique which is quiet common. If the user interface communicates via I2C or SPI a problem in the power supply can have similar effects due to bad signal integrity. So perhaps a look at the schematics can make clear if my points apply without hauling the beast out again.... Like your videos keep up the great work.
I always enjoy your videos with their informative content and humorous way to source the original culprit! It's killing two birds... Such failure is hard to solve in these multi boards amps or receivers. You know most of these Onkyo, Yamaha, and others won't even reach the bench in most cases, even if you've simply to change a few caps, a watchdog chip a HDMI chip or whatever bad component (I've even found a quartz was fried on one of these...). These multichannel amps or receivers are generally a time waste, even with a good documentation if you don't find anything catching your eyes in the first ten minutes, but when you have multiple layers of boards, fragile connections...! A transformer swap could be a real challenge, as these are poorly documented or marked (you can check voltages, but VA's are always a guess or a weight/volume guess).
Reading some of the Comment replies reinforced My use of Home made "Drop box's" I made several of them over the Years to save equipment before the Use of UPS's were more available. It is just a continuous duty Relay in a metal BUD box that is Latched on by pressing a button. any glitch the Relay drops out... Here in Central Wis the Power Co. uses Automatic resetting Circuit breakers that will try 3 times to reset. That reset is about 5 Sec's apart.. Power glitching is more of an issue now that I am out in the Boonies where I am on a mix of underground and overhead service. I do not set the Clock on the stove or Microwave anymore LOL..
The 705 is great. Very reliable unit, and sounds absolutely fantastic. The last "good" Onkyo Generation. the xx6 had failing/bad/overheating caps on the dsp board, the units after them are even worse with faulty DSP chips
Have you taken the fasia off and checked each button for a reliable low resistance when pushed. Does that front switch panel use a string of resistances connected to the buttons. Slight damp will make it go mad.
based on what happened that caused the unit to fail in the first place i would have looked at the power supply rails first. mesure there voltage and check for ripple. i recently had a TXSR804 that was having the same issue after a bad storm. one of the voltage ragulators had failed partly an was lputting unstable voltage into the control circuts causing them to act up like this. you prob already know this but always check your supply rails when something isnt working
Did the bird exhibit the infamous Magic Smoke? 😆 Thoughts at the beginning of the video, I'm guessing one or more of the IC's has given up the ghost! 👻
A local tree guy took 14kv jolt while up a tree. He didn't fare well. Surrived but lost an arm and leg. I not joking. I was working in the area the day it happened. The lights flickered and then power went off. A few minutes later sirens and a fire truck went screaming past me. I was just about to climb a pole to work on neighbours phone line. Then police cars an ambulance and more fire trucks. Couldn't see any smoke so i didn't think fire. A few minutes air ambulance landed in the high school field about a block away and a few minutes later they loaded this the guy up and the helicopter took off and flew him to burn trauma unit. He was using a pole saw up a tree and didn't see the power lines that run down that street in back yard between the properties on an easement. That's what is called not being aware of your surroundings and after that accident all of us got called in for additional training for electrical safety. Which reminds me i need to do my electrical safety refresher course this week.
hi - I'm going to ask sorry ; do you use surge protectors or UPSs-'uninterruptible power supplies'? Had no end of surges, brownouts etc etc here and use multiple UPS units as I agree surge protectors are useless. We had one surge so bad the "kettle cord "to the UPS from the mains burnt out ...... I should have framed the cord on the wall with a caption, "Gave it's life to protect others....". Joking. Really enjoy your vids....thankyou.
Surge arresters are no good or dangerous if no proper earth or grounding is made. And when it comes to stop real high voltage or high energy overflow, any basic surge arresters like those including in power bars or UPS is a potential risk for the house wirings. When you have such frequent incident or if you're in a high storm risk zone, a high power surge arrester is necessary, but it should be installed with proper wiring gauges and the nearest of the main power supply arrival...
Dave, I'm just wondering if a surge protector on the line input from the meter might not be a thing to consider. Heck with all of your expertise, you could build your own unit. It looks like you get a bunch of surges from the birds. Do these birds give you the bird? haha
@@dalemettee1147 they are not that big. They do fail from time to time. Just checked mine and the light is still on. It's not all a ays surges that blows things up. More often it is a momentary loss of power which causes a voltage in smps of device. The smps responds by attempting to raise voltage as it see it dropping. A dying gasp to keep running then power comes back on and primary returns to normal which the smps has already cranked up to try to compensate for low input and now it is way we at too high and by the time it responds the damage is done. Dips are far more damaging and surge protectors do nothing for that. Only a full time ups that runs on inverter from battery and has a changer to keep battery charged
Could be just about anything and I don't feel like chasing the dragon on this one. I have 3 more that work so if it was simple then sure but i don't need it to work that bad. It's a rainy day project for some day when i am board. My old Harmon kardon has been in storage for 20 years as a rainy day project. My Macintosh rainy day project will see the light of day first lol.
My experience with these onkyo receivers with HDMI is that one of the hdmi input chips have failed. Turns the whole unit into a brick, and Onkyo won't sell you the parts to fix it.
Had a fault like the wrong once Dave I pull apart the volume control and cleaned it the problem is everyone uses remotes and the volume control on the amp gets gummed up with crap by not being used
Yes i know and if it was the switch i would care less as it sits in a closet and is never touched but this affects everything. When I was thinking or changing inputs it was also licking out and no sound so more serious than that.
Grasping at straws ,, Check for noise on the power rails . bad regulator ? , leaky diodes in the rectifier ? did have a reciver with a damaged IR receiver after a power surge act like that as well..
i have a onkyo tx-nr906 everything works great except to volume knob that seems to like to do its own thing if i try to put the volume higher with the knob on the amp i need to go very slow or its going to go down to 0 or not move at all i wonder if it could be a cap or the haleffect sensor in the volume knob thats dying
Agree with Dave that is just a cleaning job...If it allows a simple clean you will be away. EDIT Dave is suggesting you do remove the part... You may not have to.
Yes i know. I have 2 240 volt plugs in the gatage. In my office I also have 240. Each outlet is wired like a kitchen plug, they are split phase with the top on black wire and bottom on red. The bench outlets were also wired that way till I changed them to single circuit as I needed the double breaker for the car charger plug.
I have another Onkyo in service now and another spare, and the Yamaha. So i think I am good for awhile. It's such a pain in the ass to change them out. The Onkyo sounds fantastic btw. Don't sell them short they were great sounding amps. The later ones had some quality issues.
It happened to me a couple of times to which the display was freezing. I got a heat gun onto the dts chip and also heated the video chip and hdmi chip and it came good.
Happens all the time. Lots of eagles around here. Too many. Hear about small dogs being walked off leash beginning a snack for a raptor in a regular basis. People take fido our in the beach and let him off leash and a few minutes later fido learns to fly!
@@12voltvids LOL! Onkyos scare me these days. Had two of them go bad. One from overheating, second from surge. Got an old fashioned Yamaha nowadays running cooler and faster when switching modes.
10:30 yeah dude, it's always a good idea to poke around the inside of any electronic device with your bare fingers while its plugged in and running, especially around the live circuit where the voltage and all the stuff around it is more than just deadly... you know that i was kidding, right? i mean it is more than just obvious that live circuits are dangerous, no matter how high the voltage is (110, 230 or higher)

Isolation transformers are awesome. Touching a live circuit is like a bird on a wire. Note i said wire not transformer. The metal is grounded as that bird found out. Probably the only reason he was only stunned I as because he had a foot long beak. Otherwise 7.2kv or 14.4kv or whatever that primary was would have blown a hole through the bird.
Wow, cool that the bird survived! I'm surprised after that shock and big fall. You can even see a spark when he got shocked.
The zap sound was added in post and is a clip from one of my openings.
Glad he survived too, didn't know about electrics .
