You would need the service manual in order to change the picture tube properly as there are dangerous voltages stored inside the tube also the tube would have to be set up properly as well. You can get the service manual for your model at the following link. They will email it too you right after purchase. Heres the link.

Well David, it sounds like you need to unplug and open back and try to stick your head up in set and look down into CRT's tubes, you may have phopser damage on one of the tubes, you will need to turn on to see it just be careful not to touch anything electrical

My tv is a jvc av-56wp74 it looks like 3Dwithout the glasses the colors dont line up


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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 a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

It is worth getting an estimate. From the symptom you explained, it looks like the horizontal output transistor became defective.

Blue screen


It sounds like the cooling fluid in your picture tube(s) has become dicolored - this can be seen if you dismantel the unit and view the picture tubes directly - they will appear foggy - replacing the fluid can be a time consumming and expencive task.
