The color in my TV seems to be going out.

First it was all red screen now it looks almost as if were a black & white TV. I just got a new TV and was wondering if getting my old one fixed is worth the trouble?

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen is bowed or warped.

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. YoThe color in my TV seems to be going out. - 578ba6c.jpgsee halos around images.

Phillips Magnavox 9P6040 C104 tv color adjustment help


If you turn color off and stand back and examine the screen---if it is not black and white but yellow looking you have bad Glycol in the blue picture tube which is quite common.

Easy way to know for sure is with set on and rear cover removed peek with a small mirror at the three lens---don't touch anything with the set on===each tube red,blue, green should have a picture with the set on.

Likely you will find the blue one looks like a floodlight with little or NO image/picture.

The model indicated is a older rear projection set.

If you go to a program that is black and white and turn the color off the screen should be something close to black and white.

There is a way to adjust the red screen down but it takes two people.

If you want to know how and what is involved let me know.

My Hitachi 51f510 projection tv just started to have a problem with the color. It appears that the tint is red/pink and I have no control over it.


For me to help you (I think I know what is wrong and it is fairly simple to correct) I need to ASK you something.

If you turn the color all the way to zero and go to a channel that is in black and white, what color is the screen?

If it is red or redish a simple adjustment will correct this problem.

Is the picture with color down to zero on a black and white channel (old movies) red looking?

Before you rate this information, let me know what you find. I am in California and will be available for a while.

Hitachi RP CRT Gone Red On All Inputs!!!


I want you to do a simple visual check of something that will tell me what the problem may be.

Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.

You can also turn the COLOR in the customer menu all the way off and look that way.

What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.

Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.

If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

If this information told you something you did not know and helps you rate this solution as I do this here for free.

My color seems to be more green than should be and I have tried to reset the color with no help


You have a focus/screen control box Find it and adjust the R/G/B screen drives When you first start Go to Menu turn Color off then with a mirror adjust the picture as close as you can to a black and white picture R/G/B screen drives, the little control box you are looking for will have 3 controls on top for focus and 3 controls under them for screen drives to each tube red,green,blue after you have adjusted to a black and white picture then go back and turn color on.

My lcd is in black and white or reverse color. Can that be fixed?


How do you have the cables connected to the TV? If you are using the RGB cables (Red Blue Green cables) they can be bad and just give you certain colors and make it seem like black and white. The easiest way to fix it is to get new cables from Wal-mart, Best Buy, Circuit City or any other electronic store. If you are using the Aux cables (Yellow, White, and Red) the Yellow cable may be cut or crimped so you have limited color. If you are using coaxial cable or the cable that connects to the cable box the same problem may be there. The cable may be bad and may be in need of replacement. If it isnt the cables then the color scheme on the LCD TV may be out of wack. You can fix that by going to the picture settings and changing it from there.

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
