Mitsubisi tv makes clicking sound to come on and then goes right back off

There might be a shorted capacitor in the video amplifier section. You can locate it through the physical appearance of the capacitor it is blown up. Replace it with same value but you have to get first the voltage output across the capacitor it must be within the voltage capacity of the capacitor. If the voltage output is higher, there is problem with the voltage regulator in the power supply section.

If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.If you hear strange noises like buzzing or humming noises it could be the color wheel which is a little disc that has a gamma of colors and spins at high rpms.When the light of the lamp goes through it creates the colors on your tv.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on. For parts you can find them in partstore.com shopjimmy.com or discount-merchant.com God bless.

A DVI cable does not have an audio connection, along with the DVI you still have to run an audio line from the device (DVD player, cable box, satellite receiver) to the TV. HDMI contains both audio and video.
