Not here. We don't bother with all that confusing mess.

I had no idea that Mexican Folklore taught that owls were witches.

So is this just an innocent bird dancing to the groove or is it an evil bird who's mocking the worship of God? ( I'll let u decide 🤷)

Who?

The consensus is that this is pre AI. It def seems legit to me

Anyway, I don't think we give birds enough credit for their intellect & awareness

Experienced a big "ow" moment last week. Installed a used stereo amplifier in my system to replace the other used one which no longer allowed any setting to be changed. It didn't matter what button you pushed, nothing would happen, except the power. The remote broke years ago.
I connected my mixer to the phono input, not realizing that the amp had an internal phono preamp.
Powered up Sonar, loaded a project, hit play and nearly blew the speakers and my ears!
Ouch and oops. Never gonna do that again. Knocks wood.

If you want to troubleshoot it, the most likely problem is one of hte buttons is stuck down internally (inside the switch itself, or a plastic bit from the panel has jammed between the button and the top of the electrical switch), or the ground (or other common wire) to the panel is broken or has a poor solder joint.   Have had both of those cause this type of issue on various front panels of assorted "dead" thriftstore and yardsale finds over the years.

When I wrote 'they don't do anything when pressed', they actually do. Click the CD button, the radio comes on. Push the DVD control, the TV input is activated. It's all random, you never know what you're going to get. It's a 25-year-old Denon, and the JVC I replaced it with is of similar vintage, but the buttons work. If I soaked it in contact cleaner for a few days, it might start working again. 😁 I have a newer Denon in the living room that could work except for the lack of RCA inputs, only 1 (!). Seems like everything needs to be HDMI these days.
Saving for a new receiver.

Given the age, a faulty power supply to the system MCU or other logic is most likely.  Extra noise in the low-voltage logic supply (usually 5v, sometimes 3.3v) from failing capacitors in the power supply PSU not filtering properly.     That is usually a simple fix, replacing any of the electrolytic capacitors in the PSU itself, a few bucks' worth typically. 

 

Sometimes they show obvious signs of swelling or leaking, sometmes they look perfectly normal but have simply aged out as electrolytics have a limited lifespan--typically guaranteed for a certain number of hours at a given voltage / temperature depending on ripple current they experience (whcih is a lot in many PSUs, at elevated temperatures, decreasing the potential lifespan). 

 

Less likely, it could the ground issue, but probably not the same way.  In this type of failure, it would be more likely that they use a serial data from that panel's own MCu to the MCU that does all the major systems control.  The serial data in these situations is usually I2C (IIC) and if it is not all on the same PCB then a faulty ground or signal could cause this type of problem.

Been gone a while.

Motherboard crashed, backups were corrupted, had a recording session where the engineer screwed it up (everyone deserves a bad day), but things are recovering.
