I have a phillips 60 in rear projection tv model #60PP9401. and it is exhibiting the appearance of double vision, can this be fixed economically

Projection TV sets have two very common problems oulined below.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.
  • No Audio/Video - TV Makes Chirping Sound
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from that includes replacement coolant, photos. instructions, etc

Looks uneven almost like 3d

The lenses might have moved out of line - with power off give a gentle tap to the side of lense suspected of this problem. (power off) then switch on if there are changes then you have found your problem.

good luck

Phillips 60pp9401

This set uses two convergence packs that go bad and take with them a resistor or two. You will need a repar shop to get it fixed. If it's over 10 years old, I would suggest getting a new HDTV set as these sets can start going downhill fairly rapidly past this age. If that's not an option, the repair could run over $350 IMHO.
