I have a four year old R51 model. A few weeks ago the screen went dark all of a sudden, but you could faintly see a image was still there. I took it in to a local repair shop and they said I needed a new LCD. But after replacing teh screen the computer had teh same problem within the week. When I took it back they said it also needed a new inverter and that the bad inverter had broken both my initial screen and the first replacement. Is that possible? Thanks!
