My computer monitor is a refurbished 22 inch screen NEC Multisync FP
1350 I bought from tigerdirect.com earlier this year but tigerdirect's
quality control SUCKS! When my monitor got here there was a piece of
broken off thumbscrew broken off in the right side of the port where my
fifteen foot computer to computer monitor cable attatches to that port.I
cut a little piece of plywood and cut a little notch in it and I
fiberglassed it by the side of the port and I used a plastic tie to
secure that side of my cable to the 15 pin port.
I didn't feel like packing my monitor up and sending it back to
tigerdirect so I fixed it myself.

It's a step in the right direction, but I'm going to wait. A few years
ago I bought a small laptop with a ten inch screen. Within a few
months, it had five or six dead pixels.

The computer was still completely usable, but seeing those dead spots
started to really bother me. A CRT will either work or not work, plus
the colour rendition in Corel Draw and Photoshop is still superior to
the LCD. That's important to a lot of people

I like the smaller depth of the LCD screen and the much lower power
consumption, but I'll be waiting for a year or two yet before committing.

A CRT can get dead pixels (phosophors) but it's more rare than LCD's.
CRT's usually die a slow death as the cathode emission gets weaker with
age. This makes the screen get dimmmer and less focused.

I have a Sony Wega 20" in the room adjacent to the computer/radio room. The
interference generated by this tv being turned on (my wife watches it all
the time, unfortunately) is mind boggling, especially on the 41 and 31meter
bands (7 & 9 mhz on my Icom R71A receiver and longwire antenna. What
exactly did you mean when you said you installed a "powerstrip" behind the
tv? The Sony 20" tv is plugged into a hefty surge protector. Plugging into
the wall outlet directly vs into the surge protector outlet strip does not
affect the massive amount of rfi it generates on the aforementioned bands
(wipes them out completely). Any suggestions? Please define what you mean
by "powerstrip behind the tv." Any help would be much appreciated. Thanks.

Our large (ish) screen TV wipes out everything from longwave to about
25.200 MHz. I devised a brilliant workaround by installing a powerstrip
behind the TV, to enjoy blessed silence. Other appliances I've known
and hated (for the RFI they generate): Microwaves (even when not
cooking), VCRs (Horrible hash-generators), thermostats, battery chargers,
and almost every PC printer I've ever owned. I think Part 15 should
be better - enforced.

Congratulations, though, on your new - found freedom from the noise beast!

Well, Dick, it's basically an extension - cord - box thingy with an "on/off"
switch.
Sadly, I don't want to climb into the back of the TV because it's still
under warranty.

I can definitely commiserate with you, though, because my experience is very
similar
to yours. I found that building and installing a rotatable coax loop did
wonders to
eliminate the noise, due to the fact that the loop allows me to "null" the
noise. I
was considering getting an MFJ antenna "noise canceller," but after building
the loop,
I decided that would be a waste of time.

Replace the TV with an LCD display. The Horizontal oscillator
operates a literally watts, and that nice saw tooth wave form
generates a very generous supply of harmonics. The problem with most
TV's isn't conductive as much as radiated..

True, that works but isolating the RF is elementary. Bad building practices
are no excuse for ditching CRTs. I myself like the the resolution and
clarity CRTs can display. Were talking about junk not bad technology.

I also have a Wega flat screen (CRT) near my receiver (Drake-R8B). The
television does seem to put out more RFI than the one it replaced, but
it's not a problem because of the antenna system I use. Here's why:

Zenith tv sets SUCK! I have always had good luck with RCA tv sets.

All them new cars look the same too.It used to be many years ago we
could tell the year and make and model of them old cars from a mile
away,, even at night time.
