Replace the Blue convergence IC, But you should consider replacing both of them, because if one has failed then the other is likely to sooner or later. They are large Black IC's mounted on a Metel Heatsink. I believe on this model the board is in the middle of the unit. Before you replace check the solder connection on the Ic's first you might just have a few cold solder joints, if not then replace both IC's

What you have is a convergence problem.
There is 2 modules inside your set that aligns the colors to have the same geometry and superposed .
It is a common problem in rear projection tvs ,
You don`t have to worry about your blue tube , i`m sure it is perfectly fine, it just needs to be aligned through the convergence circuit.
Most often the problem is with those convergence modules that are faulty and need to be replaced.
Hope this will help good luck

The blue is caused by the RGB gun alignment. Green is a fixed gun and Red and Blue are adjustable. In my Mitsubishi, the guns are motorized and can initially be adjusted (course) with the remote. There are more detailed adjustments that can be made if you purchase the service manual. I paid approx $19.00 on line 3 years ago and it is a complete manual. Unfortunetly I don't remember the site. To do a complete alignment, there are steps to take: starting with entering a code using the remote to enter the setup. To make a long story short, I had my tv aligned 3 or 4 times over 5 years under the extended warranty. After watching the tech, who was good, but under time constraints, it was clear that most anyone could do it if they could read and follow instructions.
