Channel logos and screen burn
So this is a little off topic but after getting my newly acquired PTV up and
running I noticed there's a faint logo burned into the upper right corner of the screen. I haven't watched TV much in a long time but flipping through channels I was shocked at how many of them display a static logo, this must cause a lot of damage with all the CRT projectors and plasma displays out there now. Is there any movement to get the FCC or other relevant organization to regulate this ridiculousness? Even if they'd move the logos around periodically it would be sufficient. Is there anything an ordinary person can do to avoid this? I'm worried that someone will leave this thing on a channel with a logo and burn it in further. |

Channel logos and screen burn
There is a lot of bitching about the problems on alt.tv.tech.hdtv, AVS Forum
, and similar forums where videophiles lurk, but no movement that is organized in any effective way that I can find. The problem is that any attempt to regulate it runs right into the 1st Amendment. Also, most people who realize the potential for burn in also know that it is rarely a problem unless one is running the contrast as high as the manufacturers set it at the factory and one leaves the same channel on for many hours. Anyone trying to get the best performance out of a set will be turning the contrast way down anyway, unless they use it in direct sunlight. Just vary the viewing and don't run it in "torch mode" and there will likely be no problem with burn in. Other problems are caused by leaving OSD onscreen constantly.

There's a lot of debate on this issue here in Europe. Some broadcasters (eg Five) have been successfully persuaded to lose the logos. http://logofreetv.org I doubt there's much chance on your side of the pond, though. Mike. P.S.

You must be driving the contrast control up at "spotlight" level. The
station logo is supposed to only be at about 7% to 10% level. At normal contrast levels, this should not be a problem. Our sets are on many hours of the day and evenings, and there are no burns from these. All the stations out here have this. -- Greetings, Jerry Greenberg GLG Technologies GLG ========================================= WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm Instruments http://www.zoom-one.com/glgtech.htm ========================================= "Leonard Caillouet" wrote in message news:94Abb.9434$AH4.4839@lakeread06...

Channel logos and screen burn
My parents got a projection TV and within months, the FOX News logo was
burned into their screen. They keep the set on several hours a day, but I was under the impression that it would take years for screen burn-in to occur on modern TVs, not months. what gives?

Channel logos and screen burn
Subject: Channel logos and screen burn
From: Sam Goldwasser Date: 9/23/03 9:20 AM Eastern Daylight Time Message-id: Turn the brightness down. Actually, the contrast or picture (whatever they call it) is the most critical. Most manufacturers ship the TVs with this control cranked to full on default. The reason for this is that consumers viewing these TVs alongside competitors units judge picture quality by contrast (like cranking bass and treble to full on audio). On my PTV (which came at 100% from factory), the "picture" level is best at about 20%. There are two benefits, it won't burn in, and the CRTs will last twice as long. John |
