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. ......D-Day Larry |

Glass CRTs are fast becoming unavailable, and that is one "solid-state" trend I heartily support. 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. mike 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. -----------== Posted via Newsfeed.Com - Uncensored Usenet News ==---------- http://www.newsfeed.com The #1 Newsgroup Service in the World! -----= Over 100,000 Newsgroups - Unlimited Fast Downloads - 19 Servers =----- |

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. Dick Bremerton, WA "Stephen M.H. Lawrence" wrote in message nk.net...

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.

Thanks. | | Dick | Bremerton, WA 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. 73, -- Steve Lawrence KAØPMD Burnsville, Minnesota "If a man wants his dreams to come true then he must wake up." - Anonymous --- Outgoing mail is certified Virus Free.

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.. |

Dick Bremerton, WA 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.
