Your tv could have one of several faults. None of which are to be tackled by anyone except a qualified engineer due to the electric shock hazard.the first problem could be the crt (tube) the second could be the componets on crt base circuit board ie resistors or ic. With a tv 9 years old it may not be economical to carry out a reair.
Did the ngineer say that it was problem with convergence pcb ?
To be honest the lil git hitting the screen is more likely to damage the screen than convergence.
Try going in to the menu then convergence & adjust red & blue to try & get the crosses white with no coloured halo around.
Post on here with results your model of tv is pretty straight forward I work for an indepedent tv repair shop the manuals are easy to get hold of thats if he even needs one.
I have a samsung 42 in plasma television which is three years old, it has a blue flickering light to the right of the television, sometimes can see some at the top in the middle, hope you can help with this problem, is it repairable.
With the set being 12 years old, I'm sure the picture tube is near the end of its useful life. You probably have a defective semiconductor, either an IC or transistor that has gone up giving you no color, but with the green picture, it is not likely worth repair.
