20 Most Recent Philips 43PP9202 43" Rear Projection Television - Page 3 Questions & Answers

replace the convergence ic. the IC# is STK392-120, replace this two ic at the same time. then put some silicon grease on the back of the IC for better heat transfer. some will work on replacing just 1 IC but I would recommend to replace both per philips advise. hope this help. regards, cebuwano.

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.

Solution #1

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.

Solution #2


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.

It sounds like the main filter board is defective as thats the power supply board for your model.

two STK392-120 convergence modules that usually cause the beeping. So I changed them both again, but I also found two open 7.5 ohm resistors are in the general area of the convergence modules, and I replaced them as well. I also replace 1 swollen capacitor that was probably going to blow in the future but not really a problem yet.

If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. Please note that there are potentally dangerous hogh voltages present inside hte set even when unplugged.

Keep us posted on your progress.

You will have to go into Service Menu to realine convergences and What was the STKs numbers you replaced/ and did you go with same part number?I think i have service code for this set will have to look thur my files.

Tint would be the control that will control the color balance, but this sounds like it may be deeper then that. Turn your color all the way down so that you have a black and whit picture. If the picture is still yellow then you have a problem with the blue picture tube.

You may have to do the full convergence alignment for all three CRTs, as outlined in the service manual for your model. Do you have the full service manual for your set which outlines the alignment and convergence proceedures?

You have a convergence problem. Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

Solution: 
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix. 

Try "hiding" the remote from the set so that the TV cannot "see" it. Hope this little trick helps...accordianman

If you are not able to adjust the convergence using the remote you need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Example: RED moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com 

Common problem when the convergence chips short out. Goto www.TvRepairKits.com and get their "chirping set" repair kit.  It includes the parts and instructions to repair the set. 

This is a common problem with this model. The convergence circuits have shorted out causing the HVG to chirp.

Goto the site www.TvRepairKits.com and get their "chirping" tv repair kit. It will fix the no audio+no video + chirping problem. 

If your set is making a high pitch sound or chirping sound you can get a repair kit from www.TvRepairKits.com.

It will fix the no audio + no video + set makes chirping or high pitch sound. 

Goto the site www.TvRepairKits.com and get their "chirping" TV repair kit. It will fix the problem of the dead set with high pitch sound or chirping sound.

On these sets, if your not experienced with this problem I would not try, but you could get the the part yourself and replace it. Call PTS 1800-844-7871 and ask to speak to a tech and he or she could tell you what you need and how to put it in. I just repaired a 51pp9202h/17 and would not want to do another. It has many boards in it and depending on the problem you could only buy another board and replace. Mine went black, I could hear audio but no picture. Thought it was the convergence board but it was the SSB the one with the Flyback on it. So after replacing almost everything I just bought another and its fixed now. So hope this helps

May not be the chips. Try this: go to remote and press 062597 then status to get into the service mode. The menu after that is easy to follow. Hope this helps

Go back recheck where you solder and connections.

Some how instead of posting this to another persons problem it posted here.Hmm Oh well you said you replaced STKs what was their numbers and you may need Service Code also to Realine convergences

You should have used 180s for replacement,and check all low ohm resistors near ics.And alot of time when you replace them you have to have service code to be able to Factory converges and realine.Need help let me know.
