How Do I Get Rid Of Spots On A Dlp TV Screen?

If its external spots that you have on your DLP TV screen, there is a special cleaner which can be bought from most technology shops and even large supermarkets such as Wal Mart. It is advised in the owner's manual that only this cleaner is used as other cleaners or water may damage the screen.

However if the spots  are on the inside of your DLP TV screen, the wisest thing to do is to get in contact with either the company you bought it from or the manufacturer. Most companies and the manufacturing company will simply swap it for a new TV if it is still under warranty. However if your warranty has ended and you don't wish to pay to have the spots removed you can remove the back of the TV and gently dust the mirrors inside as dust on the mirrors are what cause the spots to appear, however you must be careful as TV sets store electric energy inside them and can cause electric shocks when being repaired.    

Digital Light Processing (DLP) is a trademark owned by Texas Instruments, representing a technology used in some TVs and video projectors. It was originally developed in 1987 by Dr. Larry Hornbeck of Texas Instruments.

DLP is used in DLP front projectors, small standalone projection units, and DLP rear projection television. DLP, along with LCD and LCoS, are the current display technologies behind rear-projection television, having supplanted CRT rear projectors. These rear-projection technologies compete against LCD and plasma flat panel displays in the HDTV market.

The single-chip version of DLP and 3LCD are the two main technologies used in modern color digital projectors, with the two technologies being used in over 95% of the projectors sold in 2008. DLP is also one of the leading technologies used in digital cinema projection. In March 2008, TI announced the initial production of the DPP1500 chipset, which are micro projectors to be used in mobile devices. Availability for final products would show up in the market early 2009.

You must take the panel off the back of the TV and delicately clean the mirrors inside. The dust on the mirrors are what causes the dark spots on the screen.

Use a cheeze cloth with warm water. Squeese all the water out of it before you use it till it appears almost dry.

As far as internal problems, contact the company via the owners manual. It's probably still under warranty. If you have your receipt, you could take it back to the store. Some places will even make an even trade, without a receipt..

The big problem with do it yourself tv repair is, a tv stores power even after it's unplugged, making a dangerous situation. I would guess your problem is a little more than dirt. Call in the professionals, even if the warranty is up, the company will usually fix the set for less, than any other.
