I had the same problem on a 36" Hitachi TV about 7 years old. After reading comments on this and other pages I went and bought a soldering iron not knowing what I was going to do with it.
After trying to find a loose connection with the power off- with no success, I then tried with the power on. Not the smartest move, but I was able to find the problem.
If you follow the colored wires (blue, green, red, yellow) from the back of the tube they will come together at a connector that plugs into a card at the bottom of the set. That connection was no secure. Since reseting that connection I have had the clearest picture since puchasing the TV new.
I am sure it is obvious that I don't have an electronics background, and I don't have an explaination as to why this worked. I just know it did. I hope this helps someone.
