Question about Projection Televisions
If the coolant is cloudy or has debris floating in it, the coolant will have to be changed and the lenses and crt face will need to be cleaned. Coolant can be ordered from any electronic distributer

If you are getting the same problem with both TV monitors it could then be assumed it's an input problem to the TV monitor. If you are using a digital output from your receiver it could be the cabling. If you are using an analog output from your receiver it is probably coming from the receiver.
Digital video processing does have issues with darker scenes.
Can you try another video source seperate from the receiver like a DVD or better yet an analog VHS, if you still have one. Good luck and let me know.

SOURCE: colours are blurred and very red
Yes, the cooling fluid in the blue and green picture tube assemblies has become contaminated. Thats why the red is predominating. The contaminated growth cannot grow in red light and that is why the red is not affected. The only solution is to have the blue and green tubes pulled and disassembled and cleaned and new fluid installed. This is not a simple job. Most reputable shops charge around $300 to $500 for this repair.

One thing you can try is turning off the TV and then unplug it for 30 seconds or so. Then plug it back in, turn it on, and see if the problem has cleared up. If you're lucky, the problem may be solved this simply.
I know this might sound odd, but you could also try unplugging your Cable/Satellite from the TV for a while and watch some DVD Movies or something like that. I've heard of this fixing issues like the one you are having. I'm not sure why it works, but I've seen many situations where it does fix the problem.
If the above doesn't work, it is possible a wedge that centers the yoke around the picture tube has deteriorated and fallen out. That would effect the color purity. You could check to see if this is the problem by removing the rear cover of the TV set and looking for a wedge that could have fallen. It should be laying in there somewhere if this is the case. Also, it never hurts to do a thorough inspection while you have the rear cover removed to see if you notice anything else out of the ordinary.
NOTE: MAKE SURE YOU UNPLUG THE TV FROM ANY POWER SOURCE BEFORE REMOVING THE REAR COVER!
This could also be due to problem in the red cathode section in your TV.
The following could be checked as they are possible reasons for this problem:
I hope this helps! If it does, please be sure to leave me a good rating and some feedback. I would greatly appreciate it!
