    The only complaint I have about this set is that I have to watch most of the broadcast stations in the Theater 1 or Theater 2(Ex. E.R.) mode in order to eliminate the grey or black bars and prevent any burn-in. I have ordered the Digital Video Essentials DVD in hopes that I might be able to adjust the overscan enough that Theater 1 will not crop off the top of heads.

    I have read a great deal on some of the forums about burn-in and there seems to be some confusion. The majority state that you need to eliminate the bars, then some say if it is part of the broadcast( such as E.R. 16:9) then you won't get the burn. Other are changing the bar color from grey to black. Some are saying the Black bars are woarse than grey bars as to the severity of Burn-In. Since there is so much confusion I am just keeping the bars off all together.

    In addition to Broadcast Stations I also get the bars watching DVDs which are 16:9. The black bars are on the top and bottom of the screen. I either have to zoom in on the picture(DVD picture option) if I want to watch in HD format or switch to one of the 3 Theater settings to get rid of the Bars. The heads again get cropped.

    Is it possible to adjust the TVs HIT so the heads aren't cropped and still maintain a decent proportioned picture?

    Out of the Box Service Setting for my TV. As you can see I have some Functional Descriptions but most are not there. Any additional Descriptions would be appreciated.

    The bars MUST be grey - this is a half tone setting and averages the wear of the CRT over time. Black will cause the areas of the tube that are used to burn at a faster rate than the areas that are black, so accelerating the screen burn.

    As for the question about height the answer is no. DVD's that play back with bars top and bottom of the screen are mastered with an aspect ratio of 2.35:1. Your TV is 1.85:1, thus why you get the bars. I have the UK version of that set - the 51WH36, and I don't find the bars are that intrusive. The only answers are to either put up with the fact that most broadcasts are not Widescreen and many DVD's are 2.35:1, so there will be bars, or adjust the picture to get rid of the bars and accept it all looks a bit odd!

    For clarification, On DVDs which have the black bars on top and botton, that would be considered "areas that are Black"(part of the picture(DVD))? "areas that are Black" is not the same as the Black Bars? From this I am deducting that since the DVD Black bars are part of the picture it would be ok to watch the dvd with the black bars and not have to worry about Burn-In. Is this correct?

    My owners manual gives me the impression that any bars or logos ect. left on the screen for a period of time(doesn't state how long) will cause burn-in and is not covered by the warrenty. The only time figure I get is that if after 15 min there is no picture movement the set will shut off in order to prevent burn-in.
