Question about Philips 7P5441C 54 in. Rear Projection Television

1 Answer

Colors off We just received this tv as a donation to our program. There was a green haze around everything in the picture. We cleaned the red, green, and blue bulbs, the mirror, and the screen but it was obviously not the reason for the issue. We are a not for profit organization and don't have money to have someone fix it. We'd like to do it ourselves. We cannot adjust the colors and I can't find the cross hairs to adjust since first turning the tv on and attempting the 1st time setup. We'd appreciate any help. Thank you.

To find the cross hairs, you need to go into the menu, and find the convergence. In the main menu you need to select picture and then go to more and you will find the convergence. If this does not work to fix the problem with the color, you may have to have the coolant changed.

I have a Phillips TV Model No. 46PP93 0217. The


Projection sets have two very common problems.

The first common problem is convergence


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. This is called convergence.

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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Excessively bright whites...has a haze around any white items. all other colors are fine.


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 white,dull, red/orange, etc. You may even see white halos around images.

Here is a photo of a set that needs the fluid changed.

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

Blue haze on the lower part of rear Projection TV


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.

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.

Greenish haze on my Samsung HC P4741W


If you purchased it new then this clearly should not happen - if it is second hand and therefore older then the red tube could be burnt out. The convergance may simply require allignment if the set has been knocked about trying to get it to its final resting place - this would need a tech on site to set it up.

54" Projection TV


Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

Yellow haze


The blue filter is burnt out. A very common problem in Zenith DLPs. There are 3 color filters, 1 blue (a pinkish color), 1 green (a grayish brown) and 1 red (it is red) they give you your colors for you picture. This is a simple fix.

Green dot in middile of my screen


The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.
