CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

need to cahnge the coolant in the Blue CRT thats a very common problem with phillips in the blue and green CRTs

Chad, sounds like "FROGGY" coolant to me, Philips brand tv`s are infamous for this problem usually the green & blue tubes, you can confirm this by removing the back cover (carefully it`s heavy and has a large mirror attatched to the inside) turning tv on and look directly into the red lens, you will see a clear image, now look into green & blue and there probably very cloudy. Bad news is this is a very long, dirty, job and very diffiicult for a layperson, if you want to attempt it you MUST buy the service manual (any tv shop can order it for you) I would also advise you to NOT buy philips fluid as the **** they sell will become cloudy again (I use RCA cause it works and it`s cheap) good luck if you attempt it, I would advise you to calll a tech, video-tek

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

sounds like the Convergence ICs are getting ready to go. Does it appear as a outline almost 3D? If so its convergence if its more like a glowing halo its coolant in the blue CRT that needs changing.
