Question about Philips 9P5534C 55" Rear Projection Television

1 Answer

The picture has faded, and is getting harder to see

The set is almost 8 years old and I have never had the crt's replaced, I have cleaned ot the inside of the cabinet but that has not helped. I was wondering is this may be a simple repair or if I should even bother.

Your set more than likely has contaminated CRT fluid.. you should really take a look at this:

Not a clear picture


CRT projection televisions need periodic maintenance to maintain a clear picture. Typically, to maintain a sharp picture, they require cleaning and alignment every two or three years. If the television is being used in an environment where there is cigarette smoke or other smoke sources, the optics inside the television can become dirty and cause the picture to blur. Additionally, CRT focus and alignment wander over time, or physical CRT alignment can be knocked out if the set is bumped or dropped. All RCA CRT projection televisions have an "alignment" or "convergence" adjustment in their adjustment menus, which are fairly simple to use. The convergence feature is usually accessible from the main menu of the television. Check your User's Manual for the procedure to touch-up the convergence adjustment and see if you are able to achieve a sharper picture. If the optics in your set have not been cleaned for several years, or if it is in a smoky environment, the picture will be blurry and usually a brownish color, In any case, since the set is several years old at this point, it's likely due for a cleaning. This is best done by a technician, and mostly involves physical cleaning of internal lenses, the refractor mirror on the back of the chassis, and the back of the opaque display screen. An adjustment of CRT bias controls and individual CRT focus adjustments will bring further improvement in the image sharpness and clarity.

Large green wavy lines faded in background for 2 months. Then once turn on slowly fades to solid green. Turn off for 10 minutes turn back on, good picture for 3-15 minutes, then fades to solid green....


The Green CRT has shorted and will need replacement. You can verify the problem by removing the Green CRT drive board from the green CRT dont unplug the wires just slide the board off and let it hang suspended then try powering up the set if it stays on without shutting down then you will no its the green CRT for sure. You can get a green CRT from www.tvrepairworld.com

AKAI PROJECTION TV 54" - 6 YEARS OLD, DULL PICTURE


PLEASE BE CAREFUL WHEN DOING THIS PROCESS!!! YOU WILL DESTROY YOUR CIRCUIT BOARD LIKE I DID IF YOU DO NOT TAKE YOUR TIME OR ARE CAREFUL!!
What you need to do is clean the CRT coolant inside the TV. Here is a forum that I SHOULD have read before doing mine:

CRT COOLANT REPLACEMENT AND CLEANING

I was lazy and not taking my time to take care in not dripping any CRT coolant and some got on my circuit board, ( I felt confident since I had changed the Blue CRT 2 years prior) and I was only able to see about 1 hour of the best viewing my TV has ever given me since it was new, it looked like a miracle had happened. My TV was "dull" as the best way to describe it, colors faded, kinda fuzzy. I briefly researched into it again to refresh my memory then jumpted right into not really taking any precautions. I got lazy and didn't take out the CRT's like I did the first time with the Blue CRT and paid the price for it. Let me tell you, theirs nothing worse than getting a perfect brand new like picture only to loose it and hour later because of carelessness. Take out the CRT's, take your time, label everything and take pics, the reward is WELL worth it. Oh ya, you can use Mineral oil instead of the coolant that they sell at stores. Its not conductive, and dose'nt damage the circuit board if u spill a little. I used Baby Oil the first time I did it and when I went back to change the green CRT this time around it was still crystal clear, no discoloration in the Blue CRT I had done 2 years prior. I hope your results come out better than mine did!!

Color fade on phillips 9p6034


Your TV most likely has one of two 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.

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.

Picture is getting dimmer


Yes! CRT's do go weak with age and use. It is very possible that the CRT's are the problem.

The service tech can take voltage readings of the power supply, and biases to the CRT's to know if they are actualy weak.

From your description, I would thing very strongly that the CRT's are the problem.

Screen tuens blue them tv turns off


NOT GOOD NEWS... IT SOUNDS LIKE YOUR BLUE CRT IS SHORTED. THE ORIGINAL PART IS N.L.A.(NO LONGER AVAILABLE) THEY DO MAKE A GENERIC REPLACEMENT, BUT I DON'T THINK THEY ARE AS GOOD AS O.E.M.
YOU CAN TAKE OFF FRONT OF T.V. AND ADJUST THE SCREEN DOWN ON THE FOCUS BLOCK. IT IS THE BLACK BOX WITH 6 ADJ. ON IT 3 ARE FOCUS. 3 ARE SCREEN . TURN THE BLUE ALL THE WAY DOWN , THEN WITH THE BACK OF A PLASTIC OR RUBBER SCREWDRIVER HANDEL YOU CAN TAP ON THE NECK OF THE CRT, NOT TO HARD. SOME TIMES YOU CAN CLEAR THE SHORT OUT OF THE CTR. IF THIS WORKS LET THE SET WARM UP FOR 10-20 MIN. THEN TURN THE COLOR ALL THE WAR OFF, THEN SET THE BLUE LEVER UNTIL YOU HAVE A GOOD BLACK AND WHITE PICTURE. BE CAREFUL NOT TO TURN IT UP YOU CAN DAMAGE THE CTR IF THE LEVEL IS TO HIGH. ERROR 8 IS A.K.B. ERROR THAT MEANS THE CRT'S ARE DRAWING TO MUCH CURRENT.

Picture tube fluid


Magnavox are good at fluid breaking down especially blue and sometimes red. Yes you would have to be very carefull not to waste on boards, because of set CRT's are tilt this mean when you open it will start to leak. The best bet if you are willing to try yourself is to prop up set somehow to make crt's level and when you take lense off you can look underneath and open the bottom lense cover up and expose the old crt fluid and then you will need some type of suction pump to suck out the old fluid. Once you have old fluid out then you can clean inside crt and make sure you clean good. Then replace with new fluid and go in reverse and clean all that touches crt. Hope this helps!
