Television screen does not display entire image -- for example, sports scores and news ticker items are partially "cut off" (particularly on either side of screen). I've searched the menu for a corrective setting without any luck.

Re: TV Screen Does not Display Entire Image
Most likely it has a horizontal width control on the inside of the set on the main module. It is usually to the right side of the set near the high voltage transformer. I advise caution unless you understand the operation of the tv and the components near the control.

Call a television engineer. Don't try and fix it yourself it always ends badly and more expensive. Could be a board, a component on a board, a bad connection, or blown capacitors. The course is 2 years full time education.
It may be the internal backlight that is failing. When the display has failed but still has power, take a flashlight and hold it close to the screen, move the flashlight all around the screen and check if you can see anything. The display will be dark, but you should be able to make out the image that is there with the flashlight technique. If you can see an image on-screen, then your backlight has failed and you will need to replace the monitor. Weather or not you see an image is not a critical issue, but a tool to verify if the backlight is off or some other issue is causing the problem.
Note, it may be difficult to detect an image on the un-light display, for example if you have a dark image as your desktop background. So make sure to fully scan your display (top to bottom, and left to right covering the entire screen) with the flashlight technique in order to see any image on-screen.
I might need a little more detail to solve this problem - I suspect the problem is an incorrect setting on your cable/satellite receiver (assuming you are using one), but let's start with the TV.
Firstly, switch the TV on and select a channel where you can see the ticker. Then press the "FORMAT" button (above the red REC/CONNECT button) on your Mitsubishi remote control. This will change the screen aspect ratio and the current setting will be displayed on screen. Each time you press the FORMAT button the screen size should change.
The screen aspect ratio settings for your TV are STANDARD, EXPAND, ZOOM, STRETCHED and NARROW. Press the FORMAT button repeatedly until "STANDARD" is displayed on the screen. If the ticker is still cut off, you need to change the aspect ratio setting on your cable/satellite receiver.
Please note: If the TV will only allow you to select STANDARD, this is not a fault.It simply means that the aspect ratio cannot be changed on the TV because it's displaying a picture from an external source, i.e. a cable/satellite receiver.
You should then look for a button on the front of your cable/satellite receiver or the cable/satellite remote control marked "FORMAT" or "ZOOM". When you have located this button, try pressing it repeatedly until the ticker is both fully on the TV screen and the picture covers the entire screen.
If you don't have a FORMAT or ZOOM button for your cable/satellite receiver or you are unable to set the picture size correctly, leave the TV set to STANDARD and then reply to me with the brand and model number of your cable/satellite receiver. I will then be able to assist you with finding the correct picture settings and give instructions on how to set these correctly.
I hope this helps - please post back here if you need further assistance.
This is applicable to Bell Television Services (Canada) I solved the problem myself after two calls to both Zenith and Bell Television satellite service. On the bottom left of the Bell remote control there is a * (STAR BUTTON). Press this * button and within two seconds you must press the channel change button up or down. This will do two things. One; it changes the channel; and also changes the ratio of the satellite signal. There are three satellite signal ratio settings. Try this when you are tuned to a TV channel such as BNN (Canada) (Business News) or The American channel which has a stock ticker usually displayed along the bottom of the TV screen. Select the ratio (setting) that allows the stock ticker to be displayed......hope this helps.........Jim McP
