How safe is it to lift the ground on my projo?

[Claude D D]

Hey guys,
I have a ground loop hum in my system when I hook up my multi channel outputs from my DVD player to my Rotel RSP-1066(also if I run a s-video cable from my projo to my 1066)
The projo has the 3 prong plug with the ground.When I temporarily plug the projo into an old surge protector with the ground pin broken off the system is silent again,no hum.
The question I have is how dangerous is this to do on a permanent basis? Or is there any safe way to ground the projo internally or other??
Help :?

Claude, I have heard of others breaking off the ground pin to eliminate hum, but it was usually their receiver or amp. I honestly don't know what danger this would be to the PJ, but the things cost so dang much money that I myself wouldn't take any chances. I only ever had a hum problem once and discovered that some cables were in contact with the power cord. Once I moved them apart the hum disappeared.

Thanks for the input George.The cables are fine,that was one of the first things I checked.It may take awhile but I will eventually get it figured out. :?

Personally, I wouldn't by-pass the ground. If something wiggled loose inside the projector and touched any part of the metal on the projector case, the next time you touch the projector could be your last. At the very least, you'll have very frizzy hair.

With electricity, I say bite the bullet and get the help of a qualified electrician (even at their ridiculous hourly rates).

I'm less worried about the equipment than I am about your saftey.

Thanks Gordon,I feel the same way.A dedicated circuit may be installed in the not to distant future.
Seeing as I only have the problem when I want to listen to a SACD and I only have 4 SACD's it's not a real big deal.I just hook up the multi channel outs from my dvd/sacd player to my pre amp and unplug my projo.Then disconnect the multi channel out and plug the projo back in to watch movies or listen to regular cd's.Luckily I have very easy access to the rear of my gear.

How's your cable management Claude? You might try disconnecting and reconnecting following basic rules laid out by me in Home Theater section a while back. Group power cords, video, audio, etc...
