Get a multimeter at RadioShack or other electronic's store for about 7 10 dlls the check the resistance for example if its 2.2 will measure 1.1 if its attached to the chasis ans so on if its a 6.8 ohms will mesure 3.4

How to adjust the convergence setting in a phillips model 60pp9401 tv

Use your remote and goto the convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

I own a 60PP9401 60 in. Rear projection tv. My red convergance was way out of line. I placed tv in the shop a while back,cost me $300 to get it fixed! Got set home, red still out of line,but not as bad. My...

This set has an advanced menu for adjusting the convergence and what may have happened is the shop adjusted it (It is done with an original Philips remote) and then not SAVED THE ADJUSTMENTS INTO THE SET'S MEMORY.

I can if you have the remote get into the menu and adjust and SAVE the adjustments. If the set is HD the convergence will have to be adjusted two times, once in regular and once in HD.

Let me know if you have questions.

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
