faulty philips lcd

hello, i am new to the site and looking for advice on repairing my faulty lcd. the tv is a philips 17in. PF 4310. Recently the screen has not been working properly. we are getting a series of coloured lines running from top to bottom of the screen on the right hand side, the lines run from the extreme right hand side to about 6 cms into the screen. this sometimes changes from coloured lines into a black block down the same area. the tv is unfortunately out of warranty but is only a couple of years old. does this sound repairable or am i realistically looking at a new tv
