    thanks, I'll try that tomorrow, remember, I do not have a remote..

  • sutherh Jun 17, 2009

    no, I just see on your reply you suggest using the info button on the remote. Again. I'll try it tonite and thanks . I'm hoping to use the other info on this site to try and turn down the green component of the colour.



    There is also a bright, almost flourescent blue splotch on a section of the screen. Are either of these a sign that the bulb needs replacing?



    I read there is a class action lawsuit in the USA for these Zenith/LG units. Do you know it these suits apply to Canadian purchases as well?

  • sutherh Jun 17, 2009

    I tried the < arrow on the volume and pushed the menu, nothing happens, the volume just goes down. Pushing it after the menu is selected just toggles the menu on and off.

  • sutherh Jun 18, 2009

    the worst part is the green hue, do you know what is causing that ??

  • sutherh Jun 18, 2009

    60,000 hrs, you mean 6,000 don't you? This is an LCD rear projection, not a flat (thin) LCD.



    What about the green hue? Is that a bulb thing or something else??

  • sutherh Jun 19, 2009

    Thanks, I guess I can't get to the service menu with-out the remote.

You buy remote in your unit just click below;

The life span of the lamps. Flat-panel LCD screen displays have a lifespan approaching 60,000 hours. The lifespan of an LCD display is generally longer than that of similar-sized plasma displays. Some manufacturers even claim that their LCDs can last upwards of 80,000 hours when used continuously under controlled conditions (e.g., in a room with "standard" lighting conditions and 77° temperatures throughout). Just how realistic such claims are is debatable. After all, whose living room has no windows and remains at a perfectly comfortable 77 degrees year-round?
In any case, the pictures on LCD displays will show some "wear" because they are generated by powerful lamps, which, like any lighting appliance, will dim over time and with use. The picture you see will dim ever so slightly as the lamp itself dims.
Therefore, the most important thing to consider when it comes to the lifespan of your LCD TV is the actual lifespan of the light source in your LCD. LCD TVs last as long as their lightsources do. So, the lightsource in your LCD monitor is the critical component of your LCD display unit.

Hope it may helps:

    It is the main board cause the green hue because it is the controller.The main board hosts the video chipset, and manages all inputs.If it is faulty, the picture can color green haze, picture freezing or picture blurry or too blue tint also, this can be the problem.This part is the first suspect, since it covers most video functions and manages all inputs, however more parts must be tested. Maybe there some components parts is cold solder. The switch and control chip are the usual suspects because the switch experiences lots of electrical and thermal stress and the control chip is a complex IC. Also possible is a defect in the circuit board such as a cold solder joint. A cold solder joint is where a lead of a component is not soldered at a high enough temperature and results in a bad electrical connection which can respond to physical shock and thermal stress. A solder joint may also be broken or cracked because the unit or bang was dropped or hit. Look on the front and back of the board along the defective circuit to see any components that look like they are not soldered effectively or the solder connection is cracked or broken. A cold solder joint looks dull and/or bulging unlike the smooth and shiny normal solder joints. This must resolder again to be tightten and pass current smoothly.

IIf its LCD or plasma the blue spotch is beig caused by dead pixels and replacing the lamps won't solve this problem. Its no way to fix dead pixels.

Hi.
just power on the set and held the volume down (-) button in combination with one more...and kept moving down the line (was either TV/Video, Menu, or OK)....

or else try this step

Originally I got in by holding the Volume down (-) on the TV ONLY along with pressing the "INFO" button on my remote 3 times. Oddly, I believe it came on by just pressing once..

thank u

    hi..

    i am giving u the possible number of solutions to access ur service menu without a remote.



    If you misplaced your Remote Control you can still access most settings via the MAIN MENU screen when you press both CH UP (8) and DOWN (9) on the TV set.

    hi..
    Assuming that you have not experienced a failure in a circuit, your television needs to have the colour adjusted properly. Green hues are a very common problem - the green has been factory-adjusted to make grass look good, but it makes people look slightly nauseated. This is one of the many reasons why the NTSC system, used in Canada, the US, and Japan, is called Never The Same Colour.
    There are a number of controls that can be used to adjust the contrast, brightness, colour, and other parameters of the television picture. These may go under different names on different televisions: colour may be called hue, for example. This control can be accessed via the remote and adjusted as needed. However, most televisions come out of the box set up the wrong way for home viewing. They are configured by default to show a punchy image in a brightly-lit showroom. This can be adjusted, with care, and with some practice.

    However, there are alternatives...

     use a calibration DVD : "Digital Video Essentials" from Joe Kane Productions. There are other, similar, products on the market.

    The Video Essentials disk includes an RGB (red, green, blue) filter that is used with the test signals to calibrate the picture's colour balance. Most televisions only provide a single colour control - the colour or hue adjustment previously mentioned - so it is almost impossible to accurately calibrate all of the colours properly. Almost all televisions have a slight bias, usually to the red or green. With the right tools and a little work, the results can be quite impressive, particularly if you take the time to make all of the adjustments.

    thank u.

    Someone pressed 'a button' on the remote - now there is no yellow on the screen - yikes - lots of red and green! How do I fix this?


    Go to the menu screen and look for picture options and then look for color or Hue on the menu, this will allow you to change the hue and correct the color balance. I have a Sony and there is a yellow button on mine and it changes the settings to what they call Cinama scene and when I press this it makes the picture darker and more yello. Mine is a Sony and yours may be different.

    Need to access service menu/mode


    To access the Zenith service menu: Hold down the menu button on the remote control until the menu disappears. Then type in 9-8-7-6-enter. This should do the trick. Be careful what setting you change. I would recommend writing them down before you change any. Hope this helps.
