OK. Just had to make sure. If that were the problem it's far easier to cure than mucking about in the service menu.
Looking online it seems there are quite a few complaints about the overscan on your model. Reportedly, adjusting the horizontal and vertical screen size in the service menu will throw off your RBG convergence, so be prepared to recalibrate that as well in the service menu.
