Smithers III" A good CRT, like one with a Sony Trinitron tube, will blow away any LCD or Plasma panel for picture quality when it comes to black level and color reproduction. That's why those are still used by photo/graphics artists. We have some high-end Sun CRTs at work next to a bunch of flat panel LCDs and the difference is stunning. Steve For years we had a large, 3-gun JVC color monitor that was in the house when we bought it. The previous owner had spared no expense on video equipment (that was current at the time) and the monitor was designed specifically for commercial use, not as a consumer product. It wasn't a television. It had a separate tuner for that. It had the most spectacular picture I had ever seen. Unfortunately it finally died and was transferred to the scrap heap. The single gun Trinitron design was very good, but if you get close to it you will see a very noticeable characteristic of that kind of display ..... similar to the "screen door" effect of LCD projector display images.

"Steve" wrote in message .. . On Fri, 01 Feb 2008 12:19:52 -0500, "Reginald P. Smithers III" Why would someone prefer the LCD or the better Plasma models? Power consumption, heat generation, picture brightness, operational lifetime, reliability. Another big reason is that even if you go by the rated spec for Plasma length of service, that doesn't include burn-in. I use my LCD TV as a *big* computer monitor and also for playing games with the PS3. LCD does not suffer from screen burn with static areas of bright screen. Plasma does. Steve, please don't think I am arguing with you or against LCD, but your information is dated. Newer plasma displays are not permanently affected by screen burn. If used as a video game monitor for hours and hours, they may develop a temporary residual image, but it goes away in a short period of time. The older plasmas *did* have a permanent screen burn problem and the owner's manuals warned against using them for extended periods of time with static images like video games or watching in a non-wide screen mode. That is no longer true, but the reputation remains. BTW, my daughter with the two boys has a 3-4 year old plasma and the boys use it for hours and hours (too much) playing their various video games. There's no evidence of screen burn on their set. It depends on the video game and whether there are thicker white static bars, ones where the automatic pixel shift that plasmas use to help prevent burn-in can't compensate for. Yes, plasmas have gotten better wrt burn-in than they used to be. It's still an issue though. They're now about as resistant to burn-in as CRT's are. But you can still burn a CRT or a plasma depending on how you use it. You still should take some measures to prevent it. Not so with an LCD. For some good and recent info, see he http://www.plasmatvbuyingguide.com/p...tv-burnin.html Their conclusion is that burn-in should not be a major issue for the average user if you take steps to prevent it. But it can still happen. Power consumption is an issue, although the difference between a large screen LCD and a large screen plasma is not a huge issue. 100 watts or less difference. CNET did a comparison and the average plasma power consumption was 350 watts compared to 222 watts for LCD. That's 57% more power, which may not mean much if you don't use your set a lot. But could be significant if you do. When you normalize for the size of the set, LCD uses an average of 0.29 watts/sq.in. while plasma uses an average 0.35 watts/sq.in. That tells a better story for plasma since the sets are generally larger on average. Of course, those are just averages and actual numbers for real sets vary greatly. I still maintain that the plasma, when adjusted properly, produces a better quality picture than a properly adjusted LCD, and I just spend an hour or so re-confirming that. The new LCD is very nice. The older 50" plasma is better. Both are Samsungs. The difference is really only important to nit-pickers, like me. It really depends on what you watch. If you watch a movie with a lot of dark scenes in a dark room, then I think a good plasma is noticeably better. For types of programs where you don't have a lot of dark scenes or if your viewing area is well lit, the overall difference between plasma vs. lcd is less than the sample difference between even two sets of the same model. One thing though, don't get fooled by the huge "dynamic" contrast ratios that some LCD sets are touting. Only if the entire scene is dark can they reduce the bulb brightness to help with the poor black level. When there's a bright and dark part on the same scene, they can't do it. I notice that with my Samsung. When the whole scene is dark, it can make the black level darker. But if there's a large range of brightness on the same screen, it can't. But a plasma can. As far as I can see, that's really the only main advantage of plasma over LCD. Frankly, since I picked up, carried into the house and installed these TV's myself, the biggest advantage of the 46" LCD over the 50" plasma is that the LCD weighs about half that of the plasma. :-) Hopefully you don't have to move them very often.

The main thing you'll see with a trinitron display vs. other crt types (other than the obviously different phosphor pattern and the much better and brighter picture and better detail) is that the trinitron will have 2 very thin horizontal lines across the screen at about 1/3rd and 2/3rds of the way down (or up). Those are support wires for the aperature grill blocking the electron gun. I used to use a Conrac commercial CRT display for a computer monitor and a TV. It also had no tuner, weighed a ton, and looked pretty good for it's era. Not nearly as good as the Sun monitors with the flat screen trinitron tubes I use now. Man they're good. Steve |

I was about 15 years old, interested in electronics, and kept busy building speakers and amplifiers out of old, dead radio or TV carcasses. The old timer ran a small, old fashioned TV repair shop in Bethany and kept me stocked with old chassis and components, much to my parent's chagrin. Saved him from having to take them to the dump, he said. One day I decided to build a couple of crossover networks, so I visited his shop to get some tips. He stopped what he was working on, rummaged around behind his desk and pulled out a book on electronics and circuit designs. He made me sit there learning the formulas and doing the calculations for low pass, high pass and blocking circuits until I could tell him the value of the inductors, capacitors and resistors required to build the crossover networks with various frequency response curves. When he was satisfied that I understood the design theory, he then went to his parts bin and gave me the appropriate components. Pretty decent guy. Eisboch |

I had my Novice license and as it happened, I knew enough to get into trouble. While building a simple CW transmitter, I ran into a problem and my Dad wasn't around to help, so I took it down to the TV shop. I knew he was a ham because he had a tri-bander on a tower behind his shop. I walked in with it and asked if he could help me troubleshoot it. He asked a couple of questions, then did the exact same thing - pulled out the books and made me do my own trouble shooting with minor instructions from him. That was the start of a long relationship with the TV repair shop. By the time I graduated high school, I had learned a lot from him and had enough time and knowledge to pass the Master Technician test for the state of MA. Not to mention advancing in the radio hobby. Not a lot of mentoring like that around today. |

Building stuff at the component level has gone the way of horse drawn carriages, for most people. Oh .... you'll get a kick out of this. Last night some of the family were over and we were teasing Mrs.E. about her obsession with her horses. I used your line about horses being at the end of their evolutionary cycle and were basically worthless. She was quick with her response, telling me to go track the price of a barrel of oil over the past couple of years and I'd be wise to learn how to ride. Eisboch |

Hey Krauseter, just curious. You mentioned your gun earlier. How did
you get it. If you completed the application accurately, you would not have qualified for gun ownership. Do you have it illegally? It's his wife's gun! Ahh, the Dr-Dr. A gun totin' mama! |
