I need to change the flyback of my TV Philips of rear projection model 50P8341. I do not Know how to remove the damage flyback. First, I tried to remove the anodes that are connected to each of the three...


Leave the CRT's alone!!!!! You will ruin them. The red wires come out of the Fly-back. Pull the rubber caps up and then with a twisting motion pull each red wire out 1 at a time.

Colors on my TV seem to be washed out. Convergence is adjusted OK, brightness/color/tint settings don't seem to make a difference. I seem to have bright halos around all light colored images.


The fluid in the picture tubes needs replaced. It is a job for a professional. It usually costs about $250.00 for the job. You might say it's like giving your set an oil change.

Help i need the factory color settings form my Philips 50P8341 50 in. TV


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.

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.

How would you replace the coolant for a philips 50p8341 50 in rear projection television


you have to remove the picture tube, drain the fluis through the drain plug, then take the lens cap off, clean out all the crud, then fill it up with new fluid, don't try to do it while it's still in the set, you could spill fluid on the board and cuse major damage, also, if you remove the tube, usually you will need to re-adjust the convergence of the tubes, usually only the blue and green tubes need this, pretty major repair, i don't recommencd doing it yourself, but getting a qualified repairman to do it.

To get a new remote call a local TV service company or you can order directly from the manufacture. The cloudiness of your colors are caused by possibility of two things or both: 1) The mirror and lenses inside your TV need cleaning (use window cleaner & soft cloth) spray liquid onto cloth, 2) The fluid in picture tubes need to replaced. To replace fluid (ethylene glycol) take tubes out of unit, drain fluid, clean fluid chamber, add new fluid. How you can tell if fluid is cloudy? Take off screen assembly look into each light (red, green, blue) the picture should be clear. The red tube, light, is normally okay, so use as referance.

Your Red CRT may be on its way out. Try turning down the G2 screen control on the red CRT just a little. That should help for now. A new red tube wil be a reality in the future.
