Buy the ee prom color correction tool. This is a small electronic color wheel chip reprogrammer. It costs approx.$100. but the only thing it is a difficult tool to locate. Check google for ee prompt correction tool for a parts number and call your local store.

Re: Panasonic dlp tv

I just had that problem I had green spots everywhere. When the repair guy came out he changed the bulb, this did not fix the problem. Then he changed the entire system and this worked. But he had said before he ordered my new system that there was an easy software solution for it. Call a repair guy.

I have colored spots appearing on my screen when the TV is on. The spots are 2 to 6 inches in diameter and always appear in the same locations at various places on the screen. The first spots I noticed...

the light engine (optical block) is failing. there are lcd panels and light filters in the light engine. the problem your having is that they over heated and the image is burnt into the lcd or light filter. my be caused by a failing fan or just it's life span. the lcd panel or light filter are done for. you can keep calling panasonic and bug them over and over and they may send you a new tv. sony sent me one after 5 phone calls. i had the same problem. hope this helps.

I have a 1994 zenith big screen the picture is showing really dar

It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

Color of the picture is faded/green

Hello Jdillon917,

I understand what you are saying, however the devil is in the details in reference to your problem. Let me explain, DLP Televisions use what is called "Color Wheel Technology". A wheel made up of primary and secondary colors spin at a synchronized rate with the Luminance Video signal and this along with the changing of the mirrors of the DLP processor creates the color that you see on the screen (This is a high level description, but it covers what is happening). Now what you are experiencing can happen if the sync between the signal to the color wheel and the DLP processor is off center, if the color wheel is out of alignment, or if the signal to the DLP is drifting. The bulb "light" is working but something happened to interfere with the sync between the color wheel and the DLP processor. I would suggest getting this looked at by a DLP qualified TV technician, because of the nature of this problem. In addition I would request that you have the technician do a certified alignment after the problem is taken care of.

I hope this helps,

Thank you,
