Blue convergence problem with Philips model 46PP930217

After reading numerous posts I have concluded that the convergence chips need to be replaced. I have the required part number STK 392-120. The problem is I can't find the chips inside the TV. I need a schematic or some one with with some knowledge to tell me where the chips are located.

Your TV most likely has one or more possible problems.

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.

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 www.TvRepairKits.com. 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.

No picture, no sound, error code 7


Sounds like one of two problems

1) Convergence chips are shorted....One quick test is to desolder and remove both STK392 chips....then power the set on. If the tubes light up the chips were shorted. You can get new ones from www.TvRepairKits.com

2) Another possible problem is a bad HVG - AKA the flyback.

Try the convergence chip test first. Note: On some Philips sets you can just unplug cable "1516" instead of removing the chips.

For instructions on how to find/remove cable 1516 visit the website listed above and click on their tips page. On that page click on the "Magnavox DPTV3xxx Checks" link.
