No color on TV; screen cycles from widescreen to normal
The color on the screen began to shift to black and white; now it's only black and white. Also, prior to that, the screen seemed to zoom in, but now I wonder if it was switching between widescreen and normal modes. Any ideas? I tried checking for loose connections, but no luck. Thanks, Loree

This problems are a very tipical of the coded pixels on the LCD screen panel passes through the board that call the T-CON decoder board to causing this problems.Vertical colors lines display on the LCD screen panel happen by itself.Yes.The T-CON decodering board it is dying and shorting out.This T-CON decodering board sit in the middle at the botton of the LCD screen panel.Replacing this T-CON decodering board will solved this problems,if does not the LCD screen panel itself it is shorting out,than the tv it is not worth fixing,because changing the whole LCD screen panel itself it is not practical and the cost will be the same as a new tv itself.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decodering board for the replacement.
Keep in mind that not all programs and show are in widescreen format. When set to normal, you will get those black bars on the sides because the program is sized for the older TV's. Some TV's will have a zoom option, but that will cut off some of the top and the bottom of your picture.
Until everything goes widescreen, you are stuck in normal with those black bars or widescreen with the fat people.
I hate distortion in my TV image, so I am perfectly fine with my TV on normal.

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control. 4.14.2 Viewing Modes Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3). Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom. Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles. Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.
Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode will return to widescreen.
Check the aspect ratio of your widescreen DVD. I'll assume that your flat panel TV is widescreen, which would mean it has a ratio of 16:9. Some movies are even wider than that (i.e. 2.35:1), so it would be normal for you to see black bars at the top and bottom. Look for a WS DVD described as 16:9 (usually shown on bottom on back). This should fill your TV screen and not distort the image. If you still see the black bars, you will need to check your DVD menu settings for widescreen aspect, and supply more info on the DVD player and TV.
Go to Best Buy and see if they have your same Model on display and change the aspect ratio and see how it is. If it's normal there then to me it sounds like a software up-grade might be in order. It might just have a software glitch.
I have a similar problem with this monitor, i always after connecting having to go to the "screen Position and Size" setting in my ATI FireGL. and shift the screen 1 pixel, and the color and resolution turn ok, it is manual step, but better than no fix
