i know this is a old problem but in case anyone in the future here has this problem, the problem lies in your convergence board ,mainly the stk`s are shot ,you can buy new STK`s for around 15 to 20 dollars and then will need some one to take old ones of and resoldering the new ones on.
anywho if you have this problem unplug or remove your convergence board and then turn on tv and you will see a picture, all colours will be out of convergence but when you put the fixed board back in colours should realign, or you may have to realign a little yourself.
only reason i am posting on this old problem is because was just given this tv samsung hcn473wx/xac for free and decided to fix it and it now works well.

These are both CRT type TV's(3 picture tubes drive the image) with different screen sizes and the CRT's are not interchangeable
