Chances are the horizontal output transistor is blown.
Easy fix if you know what you are doing.
Dangerous, possibly fatal task if you don't.
CRT's can store a large amount of energy for days even weeks after a TV has been sitting unplugged. A 27 inch this voltage could be in the range of 25-30KV, yes 30,000 volts
So if you do not know what you are doing then take it to a shop.
