I have a phillip magnavox big screen tv it works fine but the color is too dark i think i need a picture tube

If its the one indicated here or one like it :

The picture tube type (CRT) rear projection tubes require annual cleaning.

With set off and back removed locate the three large black lens atop the chassis--hard to miss them.

The are the red, green, and blue tubes and are your light source for the picture---------if dark and they are dirty or dusty the picture will be darker and not as sharp or clear as it once was..

spray some glass cleaner on a paper towel and wipe them clean.

Do not touch anything else in set and do it with set unplugged.

put back cover on and see if picture is noticeably improved; if so do it once a year or more if in a dusty place.

Let me know if you have questions.

I have a magnavox 55 inch screen model nu is 6p5440w102. Picture is dark tried to lighten but wont brighten up anymore.

This is an older set------with back off you will see 3 large black cylinders with lens---these are the red, green and blue picture tubes.

Clean the lens with a lens cloth or paper towel with glass cleaner sprayed on the towel.

Annual cleaning of them is suggested as dust or dirty lens will cut down the brightness---this happens gradually over time and will make the picture darker and somewhat dull looking.

I do it with set on but you should UNPLUG SET and just look to see if dust on lens.

Simple and takes only a few minutes.

Let me know what happens.

If this is an older rear projection TV as the model number indicates, you can unplug and remove back cover.

Inside you will see three large round black lens---these are for the 3 picture tubes: Clean all the dust and dirt off of them with either a lens cloth or a paper towel with glass cleaner sprayed on the towel.

The lens are the light source for your picture and if dusty the picture will gradually become darker and some what blurry looking.

hope this helps you.

Problem with the Philips Magnavox 9P6034C 60 in. Rear Projection Television, had TV for 16 years. Picture gradually got darker and less clairity

the projection tubes do wear out over time and there is no fix but to replace them. you might first check to make sure the lenses and mirror are clean, do not use compressed air to clean as you may force dust between the lenses. if the picture is darker at the edges or a different hue then the coolant is likely contaminated and needs changed

Poor picture quality. Picture also tends to curve

The curving is caused by bad digital convergencr chips (2) located on large signal board. They need replaced along with blown pico fuses and the convergence resistors. Chips are huge compared to a regular IC. 2" x 1.5" and they will be bolted on fairly large heatsinks. Cloudy picture is most likely the coolant needs replaced in the picture tubes. This needs to be done approximately every 5 years.

Screen is getting darker

The most likely cause is the blue and green tubes need to have the cooling fluid changed. After many years the blue and green get clouded with algae. The red tube won't have the problem due to the red spectrum kills the algae before it has time to grow. 

The way to replace the fluid for is to completely remove each CRT from the set, remove the drain plug, drain the fluid out the tube, disassemble the lens, give it a good cleaning; then reassemble; add fluid; and reinstall in set. If you check with the site they are working on a kit that includes the fluid and photo instruction guide.

60" Philips Magnavox Projection TV Red Screen

You can also check to see if you have bad fluid problems, by looking down in your crt's with a flashlight when you unplug your set and see if you can notice any particles that should not be there. Look at all three and see if there is a difference. It should be clear, if not then you need to change fluid and clean.
It sounds as if one of the picture elements (there are probably 3 for R-red G-green B-blue) has gone bad and it is most likely the green one. Sad to say it will probably cost you more to have it fixed than it would to buy a new TV. Most places will not even look at a TV for less than $85 or so, then they will add parts and labor... if they can even find parts.
