I have red green and blue lines thru the screen

Its possible one of two thing have occurred, you have maladjusted the G screen control on the high voltage screens and focus assembly. Turn down (counterclockwise) all three of the screen drivers. Adjust each until a light appears in the each lens, red green and blue. Go slow or lines will appear if set too high. If all three lamps stay lit after this adjustment the look at your screen with color level down to zero using your remote and the picture menu. Adjust the three color drives to get a good black and white balance appearing on the screen. Now adjust the color level from the picture menu back up to normal range.
If you still get green diagonal lines after this adjustment then I would suspect that the green lens has a heater to cathode short in the tube.

Does the picture look like this?


If so I believe your CRT liquid coolant has gone bad and needs replaced.
How to diagnose bad CRT Coolant:

Note: This problem will only affect the GREEN and BLUE picture tubes. The RED CRT is never affected, because the wavelength of the red light does not promote this algae growth
General Symptoms: Washed out, blurry picture, red portions mostly OK, GREEN images have halos, BLUE portions of images may have halos or be missing entirely.Turn the color level control all of the way down and remove the screen and/or the cabinet that contains the mirror. (different for different models) Do not turn the set off or the color level control will reset to preset levels. Look directly into the picture tube lens while the set is on. First look at the RED CRT. Observe the scan lines in the picture. These same lines should also be present in the green and blue picture tubes.
After looking at the RED CRT for comparison, look into the GREEN or BLUE CRTs. If it is contaminated, it will look like there is a layer of film that you have to look thru to see the picture. There may also be swirls and other various contaminates forming. If it is not as clear and sharp as the RED CRT, it is contaminated, and you should change the coolant fluid. IF you wish to tackle this I will supply more information and instructions. This task is medium to hard for non trained people.
Let me know if you wish to get the instructions on changing the fluid.

If the glycol is bad, there is a easy way to tell:

Remove the back cover and with the set on use a small mirror--put it over each of the three Lens--red will never be bad this way.

What you want to see is a green picture on the green tube and a blue picture on the blue tube.

If instead of a picture either the green or blue look like a floodlight with no picture--the glycol is contaminated.

What happens is bacteria grows in the blue or green glycol--never the red--for some reason it does not like the red color.

Usually the blue will be the one first affected---picture will have a yellowish look over most or all of the screen (turn the color all the way down and stand back at least 10 feet and look at it,

Changing Glycol involves some important things---this stuff is like antifreeze bit ten times more toxic.

If you find yellow and want to know what is really involved respond to this posting and I will assist you.

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

Looks like you are using Component cables. There are five cables. The first three cables are Green,Blue and Red. These are the ones that are molded next to each other and are the Video signal cables. The other two cables are Red and White and they are the audio cables.
First to correctly hook up these cables you need to Connect (Match) Color for Color. (Green to Green, Blue to Blue, and Red to Red. To tell if you have correctly connected the Video cables is to look at the screen. If the picture looks ok (Normal with no colors missing then you have connected the video cables correctly). If you see a missing color meaning red, then switch the Red cables. The picture should be ok now. The remaining two cables are the Red and White cables. The "Red cable" is for the "Right" audio input and the "White" cable is for the "Left" audio Input". If all is connected correctly then you should have a good picture and Left and Right audio.

It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

This is what is known as convergence. a projection tube ussally has three picture tubes.. red green blue. they all have to align. the concave picture indicates complete loss of convergence or convegence power supply. First question on these sets Do you have the convergence option in the customer menu under setup. if you do not this is a indication of the common "FL231 fuse problem" and inexpensive simple repair. I have wrote and artilcle on this under my tips and trick section. If you do have the option then next does autoconvergence work. in you case i would not think it work. under blue and red manual convergence does the crosshairs move. if not then this is indication of convergence power supply board. if they move at all this may indicate a convergence amplifer problem.
