My 3 year-old Sony Vaio laptop has developed a problem with the screen. I think the backlight has pretty much died - when I boot up the PC everything seems fine, then the screen starts flickering and by the time the desktop appears it is extremely dark. Almost black - too dark to see the cursor. If I connect it to a separate monitor, the image on that monitor is fine. Opening/closing the screen, or flexing/twisting it doesn't do anything. I did some Googling, and it seems the problem may be with an inverter??? Does anyone know if fixing this sort of thing is quick and cheap, or is it likely to be longwinded and expensive? If it costs too much to repair, I might pick up a cheapie monitor and use the laptop as a desktop replacement instead. Any thoughts?
