Question about Philips 43P8341 43" Rear Projection Television

1 Answer

Changing coolant instructions

Yes, please set up a link on how to change the coolant in these things properly. The more information that I get, the better. I had bought a service manual online, but it does not show how to change the coolant. It has a whole bunch of pages that give circuit board drawings, part numbers for everything down to a nat's ***, and how to take the TV apart. But yes, please set up a link and hopefully a better service manual that acually shows how to change the coolant. By-the-way, is there a particular coolant that this TV needs, or can I get away with using some coolant that says that it works for all models?

The tv vision is red, green, yellow, orange, very very blurry, and it is not possible to watch the television. How could I fix it?


Please do us a favor and rate this solution after reading.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Common Problem #2) 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.

Changing coolant


I would recomend the service manual as they explain how to change the coolant, then re-align everything once your done. I would change the blue and green. Red never seems to have an issue with the coolant . I believe it has to do with the color spectrum. You wont need any special tools. The service manual will explain the safe way to discharge the CRTs as they can store energy till they are properly discharged. I will psot a link where you can get the service manual emailed to you if you would like. I work for that site and the service manuals are great, cheap prices and they offer free tech assistance. I am one of their techs. Let me know if you would like the link.
