Manual zoom button, (w & t) doesn't work. also, indicator bar on screen isn't visible.

CHANGING THE SCREEN ASPECT RATIO: ( From Manual )
The TV can display images in four different modes: Wide, Zoom, Panoramic, and Normal. Each mode displays the picture differently. To change the screen aspect ratio:
1. Press the MENU button on the remote.
2. Use the Arrow buttons to highlight the Wide icon. Press OK.
3. Use the Arrow buttons to highlight your desired screen mode and press OK:
• Normal preserves the content's original aspect ratio. Since the 4:3 aspect ratio is not large enough to fill the TV's screen, black bars are added to the left and right of the display image.
• Wide stretches a 4:3 aspect ratio picture to the edges of the screen. Since the picture is being stretched, the display image may appear distorted. If the program is already formatted for widescreen viewing (1.85:1 or 2.35:1), then black bars will appear on the top and bottom of the display image.
• Zoom expands images with black bars to fit the screen.
• Panoramic expands the display image to fill the screen.
images may appear wider than intended.
If you are watching widescreen (1.85:1 or 2.35:1) content, black bars will still appear on the top and bottom of the display image. This option is only available when the TV is displaying a 480i/480p source.

check the touch screen flex

Your TV remote control (not the cable box remote control) would have to have a button that would allow the changing of the TV screen sizes. My Sony TV control has a button called, ' wide', and when pressed will change my screen to either, full, wide zoom, and zoom. Only zoom gets rid of the black bars on my TV. If no button, than the screen size will be determined by the broadcaster.

I have the same watch. I've figured out how change in and out of 24 hour time.
1. press and hold "ST/STP" until the month/day screen is visible.
2. while holding "ST/STP", press "MODE". A 'p' visible below the month/day indicates 12 hour mode. The absence of a 'p' indicates 24 hour mode.
Manual for 4-button version is here, but all the directions are applicable. https://www.armitron.com/images/upload/XNAPE01.pdf

check the resolution of ur screen.

Hi: Check you screens format button to change screen sizes, this button may also be labeled Aspect. Seems you are in ZOOM Mode, these buttons can also be found on cable boxes remote as well try pushing them to see if screen size change. If this does'nt help then do this with the TV in off posistion. Press the Display key on your remote, Then the Five key, then the Vol up key, then press power key. This will turn set on in service mode, you will see service options do not do anything but press the number 8 on remote and hit enter. This will rest tv to factory settings. All video setups and parameters you have set in user menu will result back to factory and will need to be redone. TV should shut down on its own and come back on on channel 3.

I had a similar problem, and I fixed it with my new Sony flat screen by going into the zoom mode and then menu on the tv remote. You can then access settings such as horizontal and vertical and change them so that your screen can adjust. The only way you can access those settings is in zoom mode.

Toshiba have a zooming utility. Here are the controls for it

Press and hold the "Fn" key and the "2" key to zoom in, and press and hold the "Fn" key and the "1" key to zoom out

You will have a button on the _original_ remote that says Format, Aspect Ratio, Zoom, Size or just AR. It will cycle through Normal, Stretch, Partial Zoom, Zoom, Gray Bar, or the like. You are not in Normal but in one of the Zooms. Stretch is used to make 4x3 movies fill a 16x9 screen, may not be desirable. Zoom is used to fill the 16x9 screen with movies that have been letter boxed. Gray Bar fills the sides of a 4x3 picture on a 16x9 set with gray to "avoid" burn in. Use normal except zoom on LB. -Ken

Sound very much like you are in 16X9 mode with a 3X4 signal. That is not uncommon. Do you lose any information, top or bottom with a HD signal? Bink.
