Mitsubishi produces a wide range of large-screen TVs, both newer flat-screen models and older projection models. The technology has changed, but the basics remain the same, which can be a huge help when problems arise. You can troubleshoot most large-screen Mitsubishi TVs by following a few basic steps sufficient to root out a number of problems. With these steps, you can resolve issues easily without having to exchange or get rid of the TV or take on the expense of a repair service.
Mitsubishi big-screen TVs include a master reset button, which lets you erase your settings and restore the factory settings. This often solves basic problems, though you will need to reprogram the clock and channels when you are done.
For newer flat-screen Mitsubishi TVs, simultaneously push the Guide and Format buttons. They're located on either the front of the TV set or to one side. For older projection Mitsubishis, press the Menu button on the remote, followed by the 1, 2 and 3 buttons. The Reset screen will appear on the TV. Push Enter, which resets the TV, followed by the Home or Menu button again.
Mitsubishi has installed power savers in many of its large models, which cut down on the usually high energy consumption. If you're not aware of how the savers function, they can delay the TV's ability to turn on and prevent attached items, such as speakers or VCRs, from functioning when the set is turned off.
For projection-screen TVs, press the Menu button on the remote, then scroll down to the Energy Mode option. Set it to Standard instead of Low, and the problems should be corrected. For flat-screen TVs, press the Menu button on the remote, then go to the Setup option, then the Energy icon. Set it to "Fast Power On" instead of "Low Power," then press the Enter button. The Menu button allows you to exit the menu once you're done.
Mitsubishi big-screen TVs utilize a 16:9 aspect ratio, matching the wide screens of movie theaters rather than the more square 4:3 ratios of older TVs. Depending on the TV show you're viewing, that could result in a distorted image or an image with cut-off edges.
To fix it, press the Format key on the remote or on the set itself. It will cycle through your various image options. Stop when you find the ratio that best fits the show you're watching.
