Shocking!!!

I went to make an adjustment on my Anthem AMV30 the other day and got a small static electricity shock from touching the metal face plate. The unit shut it's self down. I waited a few minutes then turned it back on, everything works fine.

The next day, remembering what had happened, and thought I would ground any static electricity by first touching the metal face on a Carver amp that is on a shelf with other equipment, but not hooked up to anything. ZAP!!! I got static shock of a lifetime! The Anthem shut it's self down again.

I waited just like the night before, turned it on and everything works, but the sound from my DVD player (video works fine)! It was sitting on top of the Carver amp. The Anthem is now showing no signal from the coaxial cable, so I switched to a optical cable. Still no sound, or signal on the Anthem.

Two questions; 1. has this happened to anyone else? 2. If (or should) I use the chassis ground screw on the back of the Anthem to a ground, will this help with static electricity discharge when I touch metal faceplates?

Sorry for the long post, but I feel now I feel like touching something metal in another room before touching my gear. Help!

    You sure it was static?

    I doubt a ground lead will help, your components are already grounded to the wall socket through the power cords. Unless your using a cheater plug...

    No cheater plug. I am now touching a metal screw on a light switch before touching the gear, sometimes getting a mild shock, but eliminating any built up static.

    I usually ground out my personal built up static before touching my live gear.

    If you have a wool rug,thats not too good as wool builds up static like crazy.Make sure your cables are not touching the carpet also.Grab your nuts before touching your gear.

    Could it be a slight voltage build up on the chassis? And discharging when you touche?

    Take your shoes AND socks off...problem solved. The carpet feels nice between your toes, and you wont build up a charge walking around.
