Dead Combination Meter (I think)

First, I've been lurking around here whenever I needed to learn, or fix something, but now I have an issue that needs a more personal involvement. I love my prius, and have made converts out of my family, who thought that priuses (Prii?) were gimick cars!

But first, some details:
2008 Prius, touring model, I think. About 189k miles, so well used.

And the story:
I finished a 70ish mile trip from Cushing to Norman, (Oklahoma, if that matters) last night, and the car worked like normal. I drove it about 2 miles to a friends house this morning, and it worked normally, but 10 minutes later, I get in it again, to go grocery shopping, and my HUD or combination meter, or whatever it is you call the electronic display that shows gear, gas, speed, mileage, check engine light, etc, does not work. The window that controls the temperature, and shows the energy/consumption data also works, but is showing no data, aside from current battery level. I turned it off, and went about my day using my friends car (getting a late thanksgiving meal together for friends). Tonight, I get in it to go home, and the car will start, the check engine light will come on for five seconds or so, but the display will not turn on. The state of the passenger airbag will display, but nothing else will. No rearview camera display either, when in reverse.

It would also fail to turn off normally, requiring holding down the power button into the safe mode accessory mode, and pulling out the keyfob.

I've been lurking here whenever I have an issue, and found several threads detailing my issues. I would provide links, but my account isn't old enough, which I don't blame.

All of the threads place the blame on either faulty fuses, or bad combination meters.

My post here, is just to make sure that this is the current fix. These pages are all seven or so years out of date, and the last one mentioned an extension of warranty for this fix, and I was wondering if this was still valid, or what the current fix for this is.

And, if it's legal. I'm a college student, and this is my first car, I grew up thinking that messing with the odometer was illegal, and I read that getting a new combination meter would set the mileage to something other than what it really is...
