This is a problem with the CRTs(picture tubes) or the coolant chamber(s) of same. The cost to replace the affected parts with be quite high. Expect to spend $400-600 to replace the CRT(s)

What causes the yellowish hue in the centre of the screen


There are several different types of projection sets: some use 3 picture tubes, red,green,blue--if this kind of set is what you have the coolant used in the blue tube is bad-----this type of problem leaves red and green which = yellow.

Most common in Samsung, Philips, Magnavox type sets.


If it is a newer set without picture tubes (a dlp style set) yellow in the middle of the screen would denote a damaged optical light engine.

Let me know brand, model number, date made----all are on back of set.

Can't fix the color - really blue or really yellow.


Probably Blue CRT shot. Put tint back to center and turn color level to 0. Should look good black and white pic. If blue CRT shot, will look yellowish; usually more yellow around perimeter.

is the blurry all around the picture have different color like a smear of red, blue or yellow?
if it is i think the posistor of your tv is not working. it is the one who activate the degaussing coil around the picture tube the prevent color miss-landing upon opening your tv set.

RED CONVERGENCE SCREEN PATTERN BOWING AND CAN'T ADJUST


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
