When I bought this thing, used of course, three years ago, it seemed like the perfect machine for my vintage gaming ambitions of that era since it came with everything included; boxes, docs, external drive & cable. This year, throwing that weird 192 error at first and now the backlight seems to want to go out at random intervals; when I start the computer it will stay on for at least a few minutes, sometimes it will stay on for hours, and other times it is anywhere in between. I thought that these things it was either the lamps or the inverters and failures were persistent in the sense that once it was dead that was it; none of this back to life for short spurts... am I wrong?
