Probably a long shot but do any of you reckon this TV Unit would fit for the 26" R74? Its a mount job.

got this tv about 3 years ago and it's been perfect until tonight when I've noticed a fine vertical red line approx a third from the left. Anybody any ideas what this may be or how to fix it or is it likely to be a costly repair?
