Author Topic: Did I damage my HDTV? Claude S. Ayakawa Film God Posts: 2738 From: Waipahu, Hawaii, USA Registered: Aug 2002 posted 05-03-2010 07:16 PM                        I do not know why but I forgot to turn off my HDTV after watching a movie and retiring for the night. When I discovered it was still on, it was almost twenty four hours later when I was ready to watch another movie. After noticing what I had done, I turned off the set for about an hour and the first thing I watched after turning the HDTV on again was a movie on DVD. I was not paying too much attention to the picture quality when I was watching it but did notice something very strange when I switched to HD television broadcast. Instead of a bright picture with nice contrast when I had tuned to HD programming, the pictures on all the channels was flat with no contrast. Suspecting something was wrong, I switched back to video and played my Blu-Ray copy of AVATAR and the picture quality did not look as bad as HD broadcast but it did not seem to l look as vibrant as the first time I played the disc. Do you suppose I had damaged the television after I had left it on for almost twenty four hours? -Claude  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 05-03-2010 10:02 PM                        LCD or plasma? What was on the screen when you left it on? If nothing (no image) then it seems extremely unlikely for there to be any damage. If a static image with actual content was left on that long, you could have image retention. But that doesn't seem to be what you're describing.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-03-2010 10:37 PM                     LCD sets can run almost indefinitely. The only thing that will go bad are the florescent back lights. And that normally takes a very long time.... 100s of thousands of hours typically. Plasmas are fine for the long term if nothing is left on the screen.

This is different from burn-in, but similar in effect. You see it on computer monitors all the time, even high-end ones like Apple and Dell. Granted, they usually need to age for a while before this begins to happen. If you can find a pure black or pure white image and put it on your screen for an hour or two, the problem should go away if it is an LCD.  |  IP: Logged Bruce Hansen Jedi Master Film Handler Posts: 847 From: Stone Mountain, GA, USA Registered: Dec 1999 posted 05-04-2010 07:22 PM                     Is it possible that, at some point, some settings were changed or reset? There have been a few times that I have "miss-handled" a remote, and had it do strange things. Maybe you thought that you had hit the power button, to turn off the TV, but hit the reset button instead. Do you know what your settings were?  |  IP: Logged Claude S.

The only time I use the remote is when I switch from HDMI to cable TV. I watched THE NATURAL starring Robert Redford on Blu-Ray ladt night and the picture quality was gorgeous especially the scene at the train when Rober Redford struck out a celebrated baseball player almost at the beginning of the movie. This is my favorite scene in the film when everything is back lit by the setting sun. This scene is made even more memorable by the gorgeous music. -Claude  |  IP: Logged
