I have two of these and they a dirt cheap way to achieve this:

Plug your receiver into the control port and when it turns on any of the green ports will turn on too.

Depending on the logistics, a power strip with "switched outlets" will work. Basically, the "master" lamp plugs into the "control" outlet and the "slave" switch plugs into one of the "switched" outlets. This is assuming that you can run extension cords so they can both plug into the same power strip.

I have one of these for that purpose. Have my inuke subwoofer amp and cable box plugged in so they only turn on when the receiver is on.

Are you powering up from a full shutdown? If so, you could enable the 'power on after power failure' in the bios and use a remote like the Harmony home control to switch on the outlet that the computer is plugged into. You'll get some bonus vampire power savings when the computer is off too...

You could also do a similar thing with a smart power strip that has a control outlet and a switched outlet (like this) so that your HPTC receives power when, for example, you turn your TV on.

Or if you want to get goofier, you could hack a wireless doorbell to work as a power switch for your computer.

Also, it sounds like you just need to bend the contacts in the case's power switch connector to make better contact with the mobo pins.

I'm going to assume that this computer is an HTPC, and that it doesn't need to be powered on unless the TV is also powered on, and that the TV/receiver are used exclusively for the HTPC.

The way I solved this had nothing to do with Linux config at all. I just use a smart power strip. It detects when the HTPC is powered off, and then also powers off the TV and the receiver. And then when I turn the HTPC on, the power strip turns on the TV and receiver. Probably not the type of answer you were looking for, but it's low tech, it works, and it saves energy. Make sure you use hibernate (or power off) instead of sleep.

This isn't the exact power strip I use, but it's an example of what I'm talking about: https://www.amazon.com/TrickleStar-Outlet-Advanced-PowerStrip-Joules/dp/B00JPDYYSM/ref=sr_1_3?ie=UTF8&qid=1505688796&sr=8-3

Like this or this?

That's interesting.

I just realized my original comment may have been misunderstood.

The "sense" socket that I described is not actually switched off at any time. The idea is that whatever is plugged into that socket gets continuous unimpeded power so that the IR detection is powered up and you can use the remote, at which point the board's current sensing notices the extra power draw and switches the other sockets on. And to clarify, the TV goes in the sense socket, the backlight power supply goes in one of the switched sockets.

For context this is the cheapest one I found on Amazon, just to identify what one looks like (it labels what I'm calling the "sense socket" the "control socket"): https://www.amazon.com/dp/B00JPDYYSM

I'm also very curious about what you said about the TV. It sounds like you may have gotten those two buttons to push out of the service manual, and already done that digging. What's the actual error code? That's fascinating and I wonder why it's happening.

Finally, if you do decide the relay solution is the way to go, you may end up appreciating posting to /r/electronics - finding 12V that's only energized when the rest of the TV is on sounds like a small rainy day project :P

"When you turn off your [PC], the power supplied to switched outlets is removed" (The PC is plugged into the 'Master' outlet.)

One example

Neat idea. Here is an example.

A power strip with the switch wired to the cabinet. If you want to get fancy, you could get a smart power strip that'd shut everything off when your RPi shuts down.

Look for a master-controlled power strip. It's a normal power strip except that one outlet is the master, and when its power consumption goes above a threshold then it turns on the other outlets. That way when the TV is off as the master, the other outlets are off. When you press the remote and the TV goes on it uses more power, triggering the strip to turn on the other outlets. They are readily available and work really well. I have one for my entertainment center and one for my desk. https://www.amazon.com/TrickleStar-Outlet-Advanced-PowerStrip-Joules/dp/B00JPDYYSM

I use this. $13. Has adjustable trigger.

You could also buy a smart outlet strip. There is one control plug that is monitored. When you turn that device off it shuts off the other plugs and vice versa. TrickleStar 7 Outlet Advanced PowerStrip, 1080 Joules, 3ft cord https://www.amazon.com/dp/B00JPDYYSM/ref=cm_sw_r_cp_apa_5mwHybH5NFFHT
