[RFI] computer screen rfi

[kostas sv1dpi]

I used to have RFI problems with old CRT screens but I have never seen 
an RFI problem with LCD screens. I was suspected the screen' PS but it 
is strange not to have a problem and only when I run a piece of software 
to have RFI.

Yes I have read a hundred of times Jim's RFI tutorial and this is really 
good.

But I need to find first where is the problem and I will find the 
solution with RF chokes to solve it.

The common sense says that Cortland who speaks for a problem in 
computer's internet access hit the nail! I couldn't see that and this 
the next thing I will try...

I will inform you when I find it. I hope to do it in my next visit after 
the Christmas day...

Tnx to all for the answers. Merry Christmas to everyone with peace and 
health
