Phillips 55pp9401 red and green not converging even after using itellesense

I have the 55pp9401 and the red and blue are not converging over the entire screen even after I use intellisense.  I really would like to repair this tv myself.   I do have some skills in electrical work and have a lot of common sense.  Could you advise me of what to do or is it way to complicated.
thank you

Television phillips les couleurs sont moins claires

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.

My phillips 55pp9401 looks orange and purple , heres a picture of what it looks like, i tried the intellisense and it does nothing.

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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....

Intellisense button

If the model number on the set is 55PP9401/55 you have an interesting set----this model says Philips but was made by Hitachi---they made them for Philips for one year while Philips was gearing up to produce their own sets---very good set and is better than the Philips sets that came after it.
It uses (if it is this model) two STK-392-110 CONVERGENCE IC's----both need to be replaced and the set adjusted---no need for an original remote---with the set engaged in the convergence adjustment mode( there is a micro switch on the front of the main circuit board) A HITACHI REMOTE CAN THEN BE USED TO ADJUST THE CONVERGENCE. Hope this was helpful.

installing a convergence repair kit will usually repair that issue. You can get the phillips DPTV305-DPTV345 convergence kit at the following link. It contains the parts and a cd with instructions.

Converging green?

jaymz, you can`t move the green, the green tube is always mounted in the middle and is not adjustable from the convergence menu. red & blue should be converged one at a time on top of the green, once you have accomplished this the crosshatch grid will be white and that means your done :)

Philips 55PP9401 Green Out?

This is a PP15 Philips Chassis Designation.
It's based on the DP15 Hitachi Chassis w/ Different Micro.
Hitachi DP15 Model: 53UDX10B
It's most likely that the convergence amps have failed and if you have little experience in electronics I'd STRONGLY suggest you take this one to the shop.
This set takes two STK392-110 Ics and it's recommended you upgrade those to the STK392-150s for greater reliability.
They make a nice kit complete with all conv. Ic's and all (6) resistors and complete instructions. Tritronics carries them part # X480295 (Jt22053 Repair Kit).

Philip Model 55PP9401

The Green is Standard, meaning it is what you should lign the red and blue up with. But if it's not true in shape there is something wrong with the green.
