I had always heard never to do this because it can damage your equipment so now I'm pissed that he did that. What kind of damage can it do and what should I look for next time when using it? OR is it mainly you aren't supposed to do this because it can damage your hdmi connectors?

Not recommended you can actually cause a short on your hdmi board and fry an input or output on it due to this most manuals stae to turn off all equipment when connecting or disconecting cables for this reason exactly
I was careless a few times and suffered losing an input on my avr due to it after getting a very expensive repair done seeing as how no one will fix your hdmi board but jus rip out the old and install a new one i asked what caused this to happen? this was the #1 suspect from repair facility and after searching online i found a few others that experienced the same problem and were told the same as well may or may not be true but jus to be safe i turn everything off from now on

So did your HDMI port just not work at all or did it work but had artifacts and stuff?

I rip them in and out all the time, but today I saw a spark when I went to plug one in. It was like a white flash the HDMI is hooked up and working now, but I'm really going to be more careful from now on.

I really don't like HDMI, I think it's far too finicky. I love having one cable for everything but that's it.

no the other ports worked fine but the 1 port was basically dead as if nothing was connected at all no sound no pic no anything!

I would power everything down before switching HDMI connections and here's why:

I used to switch connections without regard to powering everything down until one day I could not pass any of the audio/video through my receiver's HDMI ports. Running component cable would provide video and analog out connections worked fine, but I always thought it was my my Blu-ray player. Switched the player to another set and it confirmed the problem was in the receiver. Since the receiver was under warranty, (Thank goodness for the 2yr Pioneer Elite warranty) I took it in to an authorized Pioneer repair facility. About 6 days later the receiver was ready to be picked up and they had to replace the HDMI board and a few other things. Told me to be glad it was under warranty!! Asked about switching HDMI connections while receiver/devices were on and they said it wasn't recommended, as it could end up shorting out your HDMI board.

Needless to say, you don't have to tell me twice and I now power everything down before switching connections.
