Will do.
Also tried swapping out the power cord, hoping it was something that simple. Wife clarified, she was listening to the radio when it suddenly cut out. Tried turning the keypad back on, tried other keypads, nothing.

My wife called me this morning to let me know that our whole house audio system was down. She tried to power on one of the keypads and it didn't work, so she went downstairs and tried a different one to no avail. When I got home I tried power cycling a couple of times, no change. I pulled the fuse and tested it, the fuse has continuity. I unplugged all the keypads and sources from the back, let it sit for a few minutes unplugged, plugged it back in and still no response. No LED's, no clicks, it's dead. Haven't had a chance to open it up yet to check for any obvious damage. It was hooked to a cheapo power strip, and none of the other devices appear to be damaged. I did switch out one of the keypads about 2 weeks ago. The keypad was in our master bathroom and the humidity took it's toll over the past 8-9 years. It still functioned, but you had to press the keys 1-10x to get it to register. The replacement keypad had zero issues for the past 2 weeks. Here's a link to the installation manual: Manual
I can't seem to find board schematics yet. Any help would be appreciated.

It was an issue called "Calendar Error":
Calendar error is either a bad Clock/Calendar chip (VERY unlikely), a bad 32.768khz crystal (likely) or no +5v on the chip when powered up (VERY likely). The "no +5v" is caused by corrosion on the board from a leaky battery. Crystal can just be a dead crystal or one killed by a leaking battery. I've also see that message come from gouged traces on the bottom of the board. Calendar Error is also known as "Stuck on Green Screen" when starting. Both signify a calendar problem.
In my case it was a dead battery. I desoldered the old rechargeable battery, desoldered a resistor for the recharging circuit and installed a coin battery holder and battery. Fortunately it wasn't the crystal or the calendar chip. Total time of repair: about 15 minutes.

It was the main board. Bought a replacement off of Ebay and now it's back up and running. Did have an issue with a cheap HDMI cable and it not showing a picture, but after switching that out with a better one everything is great.

Definitely screwed up. Q5506 was the original one and was bad. Replaced it with the correct one, and now......no display. Grr. Time to walk away for a bit. Frustrated.

I was hearing a few clicks from where the TV is, maybe every 15 seconds over the course of a couple of minutes. Went to investigate and the TV had turned itself on. It was plugged in, but definitely a surprise. Unplugged it for now, but noting the new development. Hopefully I'll have time to pop the back off this weekend.

Finally back home after a long weekend. I'll get the meter to it this week and see if I screwed up or not.

While I was cleaning up, I found a pair of finals. Now I need to double check my work and make sure I didn't put the bad parts back in.

I responded to one of his ads on a different site. Sold out at the moment.

Was hoping to set up an outdoor theater for a family reunion for the kids. Nothing special, will only be used 1x.
Thanks

Are we at a stand still until I can pop the back off?

No hurry. With family coming over this weekend (and next weekend) and a trip out to visit more family at the end of the month, my weekends are booked for a while.

Checked the remote. I can see the IR in the camera's screen.

I've tried three different remotes: The one that came with the TV Logitech HArmony 676 A Vizio remote from a 37" TV.

Didn't work. TV does not respond to remote.
