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

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.

you need to reset your convergence, if you have the original remote, is there an auto convergence button, if not go to the menu and do it manually, align the colors and the lines will go away

Philips 50P8341 switch blinks 6 times stops and repeats 6 blinks

I have a philips magnavox and had two problems that I recently fixed using kits from I can't say enough about their kits and help. Without them I would have never been able to fix my TV set myself.

The first problem I had was the TV was looking 3D. After doing some homework I found out that this is a convergence problem. I bought a kit, followed the instructions, and to my amazement fixed it myself.

After building my confidence with the 1st repair I decided to get their CRT fluid kit. This kit fixes the dull video,red video, or bright/halo looking video. If you have a magmavox set that is more than 5 years old your tv has this problem already. It happens on every set. As before I bought the kit, followed the instructions, and now my video looks factory new. Once again I wanted to say thanks to the team at Tv Repair Kits for putting together kits that the average joe can use.

One of my colors are not registering with the others.

you will need to get convergence done to correct the color alignment and the warped look , those are the exact signs of the convergence IC's failing
will you be trying to do the repair yourself or will you be needing to call an electronic repair shop?

Sounds like the blue convergence IC s bad. They are relatively easy to replace if you can solder they cost around 10.00 each and you should change both the red and the blue.
