Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

Blue color is now green and oranges are pink

The color on the set is off bad, but I'm not sure of the reason.  The focus and picture are still great, but the color has a very pink hue in the light areas and all things that should be blue are green.  Why is this and can a normal person fix the problem?

The funny thing is that this has been the case for a couple months, but for a few days in the middle, the TV 'magically' fixed itself and the color was fine.  It is now bad.  Perhaps a poor connection?   Please help.

I have a 60" projection tv philips magnavox model #9P6040 C104 PTV843. The color looks bad, the picture looks orange and red. What do I need to fix it and how much will it be.

You have one of two problems based on your description.

1.) Go to a channel that is in black and white and turn the color on the set all the way off.

Examine the screen and picture from several feet back----if the picture is mostly red and looks somewhat yellow in the main part of the screen you have a GLYCOL problem.

These sets have on each picture tube a sealed unit full of Glycol to cool the face of each tube (set has a red, green, blue picture tube)

If you find the yellow/orange look with the color off you most likely have bad Glycol in the blue picture tube---it never happens to the red--bacteria gets into the glycol and eventually there is no picture coming from (in most cases) the blue tube.

Loss of blue will leave you with Red and Green--mix those two and you usually get a orange/red affect.

There is a way to also confirm this with your eyes--it involves getting the back cover off of the set and holding a small mirror (with the set turned on--you have to be careful not to touch anything)

If you look in each lens you should see a fine picture--one red, one green and one blue--if as I suspect the blue tube is contaminated it will not have a picture and will look like a blue floodlight.

IF THIS IS NOT YOUR PROBLEM--GO into the customer menu and select convergence--what you are looking for is will red and blue adjust or not--are they skewed and will not move.

If this is the case you have a convergence problem--I can tell you what is involved to fix in either case.

Let me know what you find--I am here to help people.

Screen blury,very pink,green edging on picture almost colorless!

This would be a convergence issue you can run the convergence setup that is in your user manual if that does not work you are going to need service.

Double picture and colors are neon green and pink

Your TV most likely has fone of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, 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. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.


TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

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

Arched pink lines across screen. Now green and pink double stacked wording.

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

Philips 50P8341 50 in. Rear Projection Television most of the color is red

Usually if you remove the speaker grill in front there is a convergence panel that can be carefully removed. If you look inside you should see a small rectangular block with six controls. They are labelled focus and screen, and red, blue and green. Adjust only the screen controls very carefully and slowly. I would recommend reducing the red slightly brfore raising the green and then blue until the picture looks acceptable. Be sure to center the on screen controls before starting.

Faded colors

If the picture is dark or messed up too bad, the magic focus will not function, are all the primary colors faded? RED GREEN BLUE? You might have a bad CRT, would call a service man to check out.
