hello 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

Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Most likely there are electrolytic capacitors in the power supply, video path, and scan amplifiers that are starting to fail from age. This is common in many of these sets. In consideration of the age of the set, this may not be worth having it serviced.

Possible bad solder connections in convergence circuit or vertical deflection circuit. This happens in alot of equipment. After warm up, expansion of joint pulls connections loose. Recommend not running like this, could cause component failure.
