Philips Convergence for 55PP8620/79

Hi, You have answered a lot of Q's on TV convergence. My colours are all over the place as well so I guess I will need a convergence kit. Can you tell me the correct parts to get please. Also my tv has a 2.5 inch square box marked SANYO which has 6 tuning controls on it mounted in the centre of the frame above the circuit boards - is this normal? It is the only SANYO part in my Philips tv that I can see. The tv has been repaired before and I'm thinking they used a SANYO part instead of the Philips. I'm in Western Australia.

Yes the box marked sanyo is the focus and screen control box. All stk Convergence ICs for rear projection TVs are made by Sanyo, which was the origional producer of the STK series Convergence IC. You need the convergence repair kit for the DPTV series rear projection which consist of two STK392-120 ICs and 11 6.8 ohm 1watt metal film resistors. You can get the repair kit for your model at the following link , they do ship to Austrailia however they do have an international shipping charge which must be purchased for orders outside the north American continent,. They also probide free installations instructions with pictures and free tech support. Heres the link.

We no longer have the remote for model 55pp9401 and we have a convergence problem what can we do


Here's the Philips support URL for your TV:

Here's what Philips FAQ says about your convergence procedure:
Question How do I adjust convergence (align colors)? Answer Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

Press the INTELLISENSE button on the remote (under the flap). During the convergence process DO NOT press the INTELLISENSE button again and DO NOT move the Projection TV.

So, I think you're going to need to order a replacement remote.
search "replacement remote" at http://www.philips.com

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 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.

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

You probably have a problem with your convergence board. Try resetting the convergence manually on your TV - go to Philips website for instructions on doing this if you have lost the Quick Start Guide. If the manual convergence fails, then your convergence board needs to repaired or replaced.
