Mitsubishi TV Problems and Troubleshooting Repair Guide

Below are some common problems with Mitsubishi DLP televisions and some troubleshooting you can try before calling for service on your TV.

Restore Factory Settings

Many problems on Mitsubishi DLP televisions can be fixed by restoring the unit to the default settings. If color innacrruacies appear reset the PerfectColor/PerfectTint by pressing the Menu button and using the right arrow key to highlight "PerfectColor." Press "Enter," then "Reset" to restore the factory settings. If you are experiencing audio or video problems from an incoming source press "Menu" and use the right arrow key to highlight "Reset" to reset all inputs to the factory settings.

Reset the television controls

If the component settings do not fix the problem, there are two other methods of resetting the television. Press "Menu" and type "1, 2, 3" to bring up the Reset menu. By pressing "Enter," all of the settings of the television will be reset to the original manufacturer's specifications. If the television will not turn on or off, a full system reset should be performed. On the control panel of the television, press the System Reset button. The television will turn off and the green LED light will flash quickly for about a minute. When the light stops flashing, the TV should turn on.

Remote Control Problems

If the power button blinks five times after using the remote, the batteries are low and are in need of replacing. Also, check that there is no obstruction between the remote and its receiver.

The Fan is Always Running

It is normal for the fan to get louder after the television turns off. The projection television is dependent on a lamp which needs to be cooled so it does not burn out prematurely so when the TV is off the fan operates to cool the bulb down and extend life. The fan will also run if the temperature where the TV is located in the room is too warm.

Replace the projection lamp

Ensure that the bulb is cool and the television is unplugged. Use a Phillips-head screwdriver to remove the lamp compartment cover. Unscrew the lamp cartridge on the rear of the television. The lamp cartridge screws do not actually come out of their chamber and simply loosen the lamp assembly. Remove the old cartridge and insert the new one. Secure the lamp, then replace the cover and screw in tightly.
