Having problems with your BenQ Value V772 17" CRT Monitor ?

My Benq monitor model V772 turn yellowish occasionally

\015 Hi, I have a Benq V772 monitor, several days ago i was getting a vertical line which was about 5 cm wide on left side of the screen. When i knock on the monitor it becomes ok, I though it was a dry joint, so i soldered suspicious components on the pcb which is attached to the tube. Now my screen is turning yellowish from time to time. When i knock on the screen it becomes ok. Can anyone help me please\015
