We have a Philips 60pp9401, 60' rear projection tv. The images looked like they are layered. How do we align the colors without the original remote control? Using Intellisense.

Red color outline and double vision


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....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

There are three colors on the screen all make it blurry


the three colors in your screen are off alignment due to a color convergence failure. Usually due to damaged convergence power amplifiers(mounted on heavy looking metal heat dissipators)located in the D board. Replacing them usually takes care of the problem, sometimes there is further problems that arise from this failure some pico fuses located in the G board(power supply).

Hi,

The most common problem with all 3 tube rear projectors is a damaged convergence circuit. The Samsung TVs are easier to repair than many others and the numbers that break down is not excessive. For every Samsung with a convergence problem there are a large number that did not breakdown. The fault is caused by bumps or noise in the AC power, not the TV design. This usually produces colored outlines around heads, etc.

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

This requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.
