Question about Philips 55PW9363 55" Rear Projection HDTV-Ready Television

4 Answers

Red CRT board not working. Blue seems to be going also.

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?

    where is your "area". The shops around me want $50 just to tell me what's wrong and then they'll"go from there".

    Thank you very much for your help.

    My local shop just told me he wanted $100 each to change the fluid. Does that sound about right? He also said that is doing a "house call". I saw the kit at tvrepairkits.com for $50 for the 2 bottles and I think i'm going to do it. It's worth a try. I'm now on a mission with this thing!

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

  • 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 directiRed CRT board not working. Blue seems to be going - 2c07611.pngnvergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #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.

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.

    I am in the South Texas area.As a shop owner/operator I can only make money if I repair your set.Shops make more money repairing sets rather than giving estimates so most shops want to actually fix your set.The problem that you have is now you have another problem as well as the original problem (no red).You have money already invested in this unit and I assume you`d like to get your money`s worth.I can tell you that if you did turn the red screen control up too high on the screen/focus pack, the unit would simply shut down and not cause any damage to the red CRT or CRT module.A shop that charges an estimate fee requires this due to estimate refusals.Basicly it`s a way to prevent people from dropping off junk that they can`t get rid of and to weed out the serious customer prospects. It takes time to go through these units and give an accurate estimate especially if someone else has been in the unit. The $50.00 est fee should apply to the final repair cost should you decide to go with the shop est, if not it goes towards the time invested in looking at the unit.Let the shop know that you have educated yourself with what may be wrong with the set, and let them know up front what you have done to the unit and how much you are honestly willing to put into the repair.Like I said they can only really turn a profit if they fix your television at a fair price that you agree to.You are already out some money and the set is still not repaired.We can guess at what may be wrong with the unit,order some parts and still not get the unit fixed.Or you can spend 50 bucks more and know what the problem really is and make a solid decision.Use this thread to keep me up to date as to what you decide and what the shop tells you(should you decide to take it to them).I can let you know how much parts should cost and how long it should take to do the actual job. Hope this helps and please rate my information.

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.

SOURCE: The Blue has developed an arc on the top and bottom

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.

SOURCE: Sony KP-57WS500 convergence drift

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.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Screen turns blue and suddenly tv shuts off....red light on front blinking


The Blue CRT is the most likliest cause and will need replacement.You can verify by removing the Blue CRT drive board if the set powers up and stays on you will know the Blue CRT is causing the shutdown.

Blue CRT issues?


Yes the puddle is related to the Blue CRT coolant leaking. You are most likely going to need a new Blue CRT drive circuit board and quite possibly a new Blue CRT if the CRT got too hot from not haveing a sufficent supply of coolant. You can get replacement CRT drives and CRts at the following link.

Blue Screen and TV shuts off


Here's a shortcut to what the blinking codes mean.
http://www.somelifeblog.com/2007/08/sony-tv-led-blinking-codes-what-does-it.html
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)

I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)

After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256. Here: http://store.tv-repair-service-salinas.com/8-733-649-35.html

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.

SD-643HD5 64 in. Rear Projection TV


I had the same problem which was caused by a bad solder connection on my Green CRT driver board. The fix isn't too difficult if you've had some soldering experience.

1) Determine which CRT is going out (Reg, Green, or Blue). Looking at your convergence adjustment screen will help.
2) Unplug TV
3) Remove the front panel
4) Locate the driver board attached to bottom of the bad CRT.
5) Locate the two large heatsinks on the driver board, each has a transistor attached to it.
6) Touch-up the three solder connections on each transistor. Adding some new solder helps.

How to replace red crt on 52" RCA


When a red crt goes out and wont light its usually another reason such as a transistor or even faulty CRT pc board that causes it since the set powers up the other two tubes. Go to this link and leave them an email and list the model number and tell them the symptoms they will help you out with it, they are real good with the RCa sets. If the red tube was shot it would cause the set to go into shutdown or throw red retrace lines across the screen. Heres the link,

Blinking red power light - set will not turn on


Were the pale blue lines real thin in a slight diagonal from bottom to top of your screen? If so you either have a bad component in the blue drive, Blue CRT socket or your Blue CRT is shorted.Try removing the blue CRT socket and trying to power up your set for a moment without the blue socket attached to the tube. Be sure the CRT socket doesn't touch any components when you try this. Let me know if the set starts up without the blue.

Red CRT is dim....


Yes I did. You will need to get a service manual for this TV set to trace the voltage coming from the sweep power supply. If this is a problem that is new after you replaced the convergenbce4 board, you for sure have a broken wire or connection somewhere in the set. Have seen this happen may many times after a novice repairs a TV set. Good Luck
