    I have been servicing TVs for years. One thing I learned,
    when I see a picture, I can usally tell if the picture tube is getting "soft"
    (below normal emission). When I see this in TVs that are not very old,
    I will check the picture settings (via menu), and sure enough, almost every
    time, the "Contrast/Picture" and/or "Brightness" is turned up full or almost
    full (high). I always reduce the settings and tell the customer. Most
    times, this is the default setting from the factory, and you know what that
    means? Shorten the life of the TV requires replacement sooner.

    I generally turn all my monitors and TVs up bright and the contrast on high
    too. The only ones that dont seem to need it for a decent picture are

    Actually you can adjust the bright and focus from the flyback

    I find that if I buy a monitor or TV, the focus can always be tweaked
    just a little bit at least to get a sharper picture. Sometimes this
    adjustment can be made without opening up the unit, but not usually.

    Anyway, the bright can be adjusted quite a bit from the flyback as

    The only thing I'm concerned with is the CRT. Sometimes you can see
    that it has a bit of a green background and there's nothing you can do
    about ti. Sometimes it's due to it's age and how much it's been
    used...and sometimes it's like that right from the manufacturer.

    Here's an interesting thing I found while fixing a monitor the other

    I notixed the manufacturers label was peeling off the CRT. It's said
    it was an LG CRT, but had a Hitachi manufacturers label right
    underneith. The company who made these monitors was called
    "Hi-Vast"...and are likely no longer in business. The FDA were after
    them for a few reasons as well....anyway. I'm just saying this to
    illustrate the point that you might not get a "NEW" Monitor or TV even
    if you buy it as new. Best to stick with a manufacturer with a good HR
    dept. ;)
