The convergence ICs are usually the problem there are two of them STK392-040 which need to be replaced and possibly the 4 150 ohm 1watt and a couple of the 3.9 ohm 2 watt resistors this is a fairly easy repair if you can solder. You can get replacement parts at the following link and they provide free instalation instructions with pictures so you can do the repair yourself.
here's the link.

You have bad convergence ic's. You can take the convergence board out yourself and take the part to a repair man to have him replace the ic's. I've had it done twice on my tv, it cost about 200 bucks.

It seems your TV Samsung HCM4215W has problem in convergence board and need to be replaced.
You can get that board from Parts Store on $76
If you have bit electronics knowledge and know how about tv repair, you can replace it by yourself or get help of local tv tech person.

Ghosting and distortion


You can buy just about anything you want on-line by searching.
 The convergence amplifiers are large, 2 inch x 3 inch IC's that
 are mounted on the largest heatsink(s) in your tv.Some Samsungs mount the convergence amp board up high,above the
main chassis (easy pull) or down low on main chassis.The part
number is Stk392-040.Change both for reliability.I use panasonic
brand  = never had a call-back failure yet.Reset alignment after
changing IC's. ..........T.
