Question about Televison & Video
My display is fading in horizontal chunks that line up with where the LED strips of the TV should be. I've noticed the top left rectangle which was well lit has also faded within 24hours of first noticing the problem. Is it safe to assume replacing the LED strips will fix this or could it be a problem with some other part?

There is a cold solder connection on the display device, on the display driver board, or on or in the power supply that supplys the display voltage to the driver board. The only way you can repair it is if you have some soldering experience and or some electronic troubleshooting skills. If you go in and start poking around, and you poke at the wrong thing, It will smoke on you, as solid state electronics are very unforgiving when it comes to shorting out something, even if its for a blink of an eye!!! If you really like the unit, take it into a repair shop, as it should'nt cost to much to repair. If the units 3 to 6 years old, Maybe its time to think about upgrading to a newer unit??. Good Luck

I had a similar problem with my InFocus LP600 although my black stripe was straight up and down. I am guessing this is caused when the unit is bumped or dropped. This is not an easy fix unless you have a lot of experience with small tools and parts and you may need an extra set of hands. I found some tiny alignment screws under the lamp cover and hidden beneath a peel-off 0.5" x 2" black plastic strip. The screws are located between the bulb assembly and the main projection lens and are oriented 90 degrees apart around the light projection path. The trick is in getting the projector to temporarily function with the lamp cover off -- it has an interlock tab on one edge that pushes on a microswitch when closed. We turned the projector upside down but raised on some slats for heat dissipation, gently held the interlock switch in with a small screw driver, and plugged in the power cord. After pushing the power switch to get the image, I adjusted the tiny screw that is angled towards the front of the projector and the stripe dissapeared! Since your stripe is angled, you may need to adjust both alignment screws. The screw heads are very tiny torx bit types but I was able to use a 3/64" (.05") allen (hex) wrench that came in a set of cheap jewelers type tools that are widely available. Be very careful while operating the unit with the lamp cover off as there are very hot surfaces and exposed wiring.

Why does my sharp Aquos TV go out of resolution everytime I turn off the Wii game that is hooked up to it? Then I can reload Optimum cablevision- all I get is the program guide. Help

I did a little research on the Texas Instruments Website and here is the answer.
Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
