    I will try one. The original cable is a new 50ft gold plated DVI cable just as an FYI. I will report my findings soon. Thanks.

Had tv fot about 7 years, at top center of screen an area has appeared that is yellow in color. How can I fix problem?


If it's a 3 tube projector, the front of some of the tubes are cooled by an oily substance. this oil is replaceable. If it uses a light bulb, the bulb can be dimming, the color wheel may need to be cleaned as well as the lenses in front of the light. The DLP chip can also be going bad.

My tv has black splotches or pools on the bottom


If the splotches are a shawdowy black and look like mold growing between the Lens, its most likely dirt or water spots on the bottom of the large mirror. I cleaned mine and missed a few water spots on the bottom of the large mirror and the splotches (spots) showed on the screen. Other than Dirt, or water spots, There is nothing else that I can think of that would cause this. Unless the Someone has cleaned the screen and it soaked up between the lenes. But it Takes about 30 minutes to disassemnble, give it a good cleaning and put it back together.

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.

Yellow splotches inside screen?


Hi. I would need more info, it sound like you have damage the screen's, at this point no warranty would cover it, you can try. The problem is the voltages between screen's acking causing the smear on your screen. If it is a rear projector lcd then it is the engine, or obto some call's it.

I hope this helps
