Question about Philips 55PW9363 55" Rear Projection HDTV-Ready Television
I was given the TV knowing it needed to be fixed. Did some research here and figured it was the convergence chips/resistors. I ordered the kit, replaced everything (very simple) and the TV was working.."good". I knew that i was going to have to re-converge the colors the best i could but i could not get them perfect. When i got them the best i could the color was still off. I think the blue coolant needs to be replaced because that is the color that seemed to be missing the most. The green is very good. Well, when i started adjusting the colors on the focus block i think i blew something on the red crt board because the red will not come on at all now. I might have adjusted the color to high. So, now i need to order a new crt board and change the blue coolant.
I don't know how to change the coolant. If anybody knows i will be greatful.Also, should converging the colors be "easy" with the convergence screen or does it need to be done by a professional?
I changed oil also...If you can read and have eyeballs to view the included pix from www.tvrepairkits.com its a pretty easy fix. Im only a little tech-savy and it seemed to be ok. Just be careful when removing/replacing plugs for the oil inlet...my green plug "feet" cracked and had lil oil leakage when it warmed and expanded the fluid causing a short in the middle board. In seach of PN-1F10991 now, lol.

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
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 directiRed CRT board not working. Blue seems to be going - 2c07611.pngnvergence 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.

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.

Had the same exact problem after replacing the coolent fluid in blue and green
i found that the red picture tube socket needed to cleaned with electronic cleaner
and ran some sand paperon the picture tube prongs and make sure the prongs are all straight before you plug the socket back in
seems to be working ok so far

Converging the unit is pretty simple,but changing the fluid is a pretty challenging job if you have never done it before.Adjustments on the focus/screen pack are unecessary for a convergence job or even a fluid change.As a servicer I see more televisions ruined by individuals that try to fix them.I figure that you have about $75.00 in parts invested in this unit already and it`s still not fixed.If you order the fluid you are looking at another $30.00 so you are $105.00 in the hole and the unit may still be unrepaired or unrepariable.I repair these units on a daily basis and in my area I charge between $225.00 and $275.00 for this job.When the job is done the unit has a like new picture.If you want to invest in a television that someone gave you I figure that letting a professional do the job will benifit you in the long run.Make some calls and find a service center that is confident in doing this repair.I know that there are some shops that won`t change fluid due to it`s difficulty level.I fix these units all the time and it is well worth it to my customers because they end up with a like new set.As you may have researched the problems that Phillips projection units have are very common (convergence amps,and fluid).After these problems are corrected you can easily get another few years out of the unit.Good luck.

SOURCE: convergence problem
Part # STK392-040 X 2 Do not use generic-they won't hold up.
I use Panasonic brand with no recalls------wholesale cost about
30.00 each. Always replace both at same time = more efficient.
After replacement, alignment may be needed = let me know.
Please rate this solution...................T.

Thats a very strong possibilty the phosphorus may be burned off the CRT face. Does the blue project when powerd up and looking in from the raer of the set? Look into the blue CRT lens while its playing If you can see a clear picture I would think that you have some open resistors in the blue circuit, If you cant see a picture its time for a CRT. If you need a CRT let me Know I have a good source for them Used.

The KP51WS510 has the two STK392-560 ICs on the D board ( Brown Board laying flat on the left side) you will see the large heat sinks with the fins on it. The ICs are mounted to the heatsinks. In that model you will need to check the 6 Pico fuses right next to the heat sinks, and there are also 2 additional pico fuses on the G board ( where power cord plugs into) that will also need to be checked.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.
