The color projected is a darker tone than what it should be, almost appears to be too much blue instead of true color. It will work fine for a while and then the color problem appears after a while. Have replaced the bulb with a new Sony bulb. Problem still persists.

This is usually caused by a defective CCD image sensor and can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired qualified service technician.

I have a PT61SX60 forsale. It works too. Anyone want it?

that means that the phone needs to be unlock by the network provider

I replaced two convergence chips the resistors were all fine. This took care of the 3D look. I also replaced the coolant in the blue and green although it was the blue which was badly contaminated. The picture is now clearer than before but I am unable to get color. I can see vibrant colors when I pull up the TV's menu. I can see the colors in the convergence menu as well but no color in the picture. The color controls only make the picture brighter or darker. It is sepia in color not black and white. What could this be?

sounds like the blue convergence or the Blue CRT needs a coolant change. If the picture apaers 3d its the Convergence. If the color seem abnormal or not true tones its the CRT coolant

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Good Day;

More then likely your 2005 MODEL has a bad "LIGHT ENGINE". Call an Authorized Service Center and have them give you an estimate, then call MIT's and try to get them to give you a "CONCESSION". It's costly. Good Luck, big IRISH.

What kind of computer are you using and what are the connections to the projector. 

Crt coolant needs changing in the Blue and Gree CRTs red usually isnt affected.

call tech and suggest to balance your screens ..they will know the procedure.
