NEC V260XG temperature error


The most common cause is dust inside the projector that leads to overheating & auto shutdown. If you have an air compressor you can use the blow tip accessory to blow as much dust out as you can without taking apart the projector. You may get by using a can of compressed air available at Walmart, etc. electronics section. Concentrate on vented areas & where you can see or hear any fans. Do this outside so it doesn't make a mess. If you know how to take out the lamp there's usually close access to the main cooling fan through the lamp compartment, blow air through there & it will follow the right path to exit correctly without blowing dust all over the inside.

After projector is on for a lilttle while the pic flash an changes to blues an greens...just changed the bulb an it has did it again..


hi,
first of all check the tint setting on your projectors picture menu.
if not get the correct color then, your projector is a dlp projector that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for counting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same.
i have added a video how to clean the color wheel . not the same projector.

ok

My panasonic hdtv seems to have developed a yellowish tint to the screen


Sounds like the polarizing film is burnt on one of the three colored lenses that are located next to the projector itself. In order to fix this this it is necessary to remove the ballast and projector units, then disassemble the projector housing to expose the lenses. there are green, blue and vermillion (reddish) lenses. the vermillion lense is the one that causes the yellow tint after it has been damaged.
searching for the pt-43lc14-k service manual (the 'k' version is the more complete one) will provide you with daigrams and such.
I am currently undergoing this repair myself, thus far we have disassembled the television and are waiting on new vermillion polarizing film in order to complete the reapir. Good Luck, it isn't too difficult. Just take lots of digital camera pics (for screw location and sizing) and you should be fine.

Slight color changes on both sides of the screen


What you have , sorry to say is burnt CRT's this is caused by watching tv in the 4.3 mode , which shrinks the pic on both sides. so now the phosferous on each crt is only use in the center, that leaves the outer edges fresh and as new
There is no way to fix thin outher than replacing the crts sorry

Black squares or rectangles over picture


It's the closed captioning. The reason it doesn't go away when you press the "caption" button is because there are four option for closed captioning: Text 1, Text 2, Text 3, and Text 4. The fifth option, which has no designation, is the "off" option. Using the remote, just click on the "caption button until the option has no designation.

Mine was a large black rectangle in the middle of the picture. It's not like Nina3's problem.
