When the lights are off in my room & Im watching the set I can see a transparent hole in the center of my speaker grill that emits light from inside the TV-is this normal. I have the 507. For a short while I had the 467 & I dont remember this
I tried taking a pic. Its not very good becasue I had to do it in the dark, but you can see the light. The hole is shaped like a kidney-the smaller inner curve part wrapping around the bottom of the chrome light indicator on the grille. If you look close at the pic you can see the chrome center at the top & barely make out the kidney shape
I think the grille is removable... maybe you can pull it off, tape up the hole, put it back on. Besides the distraction, you could be looking at unfiltered UV light for hours which could be burning the same spot on your retinas (worst case scenario).
I see some light coming out of my front grille as well (5065), and even more out of the rear onto the wall. All of it looks ambient, not direct, and I was not concerned about it until now. When I get home I will take a closer look, and try to block the light from coming out of the front.
All the bulbs emit some UV light... it's pretty high, around 20-30% or so.
UV light of that intensity is VERY bad for your eyes, if you stare into that very 100W lamp for a few hours you'll find yourself permenantly blind. A small pinhole isn't as bad, obviously, but if it's hitting the same spot on your retinas, it could be.
Duvetyne is a black, light absorbing cloth that you can buy to line the inside of your RPTV in order to cut down on ambient light, which should thus lower black levels and in some cases perhaps even helps with internal reflection issues.
Different displays and different technologies respond better to this treatment. For instance I noticed a bigger difference in my Hitachi CRT RPTV after using Duvetyne than on my DLP.
To put it in quantifiable terms, using Video Essentials, before I used the Duvetyne I had brightness set at 45... after using Duvetyne I was able to set it at 43. If I didn't already have the Duvetyne that difference would hardly seem worth the effort, but since I have plenty on hand it was just 30 minutes-worth of work.
Also, as with any other in-home tinkering of this sort, it should be noted that opening up your RPTV to install Duvetyne would likely void any warranty on your set. When i needed work done on my Hitachi I went through the process of taking it out and then putting it back in again after the work was done.
I've been looking at the benefits of this duvetyne thing (and velvet and super-black krylon, etc) and it seems like the benefits are darker blacks and improved color saturation.
So, what I don't understand is the difference in your brightness setting. In theory, if the black level was deeper, you'd be able to actually raise the brightness and keep the black levels the same (after duvetynning). Why would you drop - or be able to drop- the brightness levels after the treatment?
